Review: Bose Soundlink Mini II - lots of improvements and still on top?

The original Bose Soundlink Mini was released nearly 2 years ago and managed to change the current portable Bluetooth speaker market completely. While most compact portable speakers prior to the Soundlink Mini pretended to sound good with phony claims like "the JAMBOX delivers shimmering highs and thumping lows that you can literally feel - the richest sound all in the palm of your hand" 
or even more exorbitant the Beats Pill which cost exactly the same: "the Beats Pill produces powerful sound [...] enjoy soaring highs and deep, booming bass" it was finally Bose to show what kind of "thumping lows" was really possible to squeeze out of enclosures that small. The Soundlink Mini was not perfect though and many complained about the "thick" sound and still seemed to like their Jamboxes more. Others complained about the lack of handsfree or USB-charging. But the huge success and what probably became the most popular portable speaker on the market, the Soundlink Mini managed to sell more than 10 million units according to some sources. Recently the Soundlink Mini II hit the market and it seems as if Bose didn't try to revolutionize this model but rather improve on numerous aspects in detail.
Let's see if they managed and if the Soundlink Mini II is really worth an upgrade.

I already made a review of the original Soundlink Mini when it was released but the review was still in German and I never prepared any English review of it. Therefore I decided to catch up with the Soundlink Mini II now. Although there is lots in common between both models, the Soundlink Mini II has nevertheless many new features which first appeared with the Soundlink Colour. I will try to treat the Soundlink Mini II as a completely new speaker, but I will also try to point to the most important changes compared to the original model as far as I can for all those who play with the idea of replacing their old model with the new one.

The Soundlink Mini II comes within a slightly shorter box than the original. The original Soundlink Mini box had a hidden extra compartment at one of the sides containing the necessary EU-adaptor for the power supply that had foldable US-contacts only. But obviously many owners didn't notice this compartment at all and complained about the missing adaptor rating the speaker with 1 star only at With the Soundlink Mini II everything is inside a single box now. The speaker is still on top warped into some cellophane with all accessoires and manuals below inside a kind of drawer-compartment. The speaker comes in 2 colors now, black or "carbon" and thanks to the Bose Experience Center in Vienna I could borrow the grey or how Bose calls it "pearl" version. I would have preferred the carbon one though, as I personally think that this one looks really gorgeous. I think that even the old silver/grey version of the original Soundlink Mini looked better than pearl, but carbon is really eye-catching now.

It seems as if the accessories are matched to the color of the speaker. The carbon version should come with a dark power supply as well as dark charing cradle and dark USB-wire. With the pearl version all accessories are light grey.
As you can see the Soundlink Mini II comes still with an own charging cradle, but this time the charging port was moved to the back instead of the side. You do not need to use the cradle at all and can attach the cable also directly to the speaker, but I found the cradle to be really useful as you can simply place the speaker inside when it needs recharging without having to hassle around with any wires, or looking for the correct side of the USB-connector.
The biggest news is that the Soundlink Mini II can be charged through MicroUSB now. This was maybe the major downside of the previous version for many owners. With the included power supply which offers 5V @1600mAh it takes slightly more than 3 hours to fully charge the speaker. I am not sure how long it might take from a 500mA USB-port. The new charger has no foldable contacts now and it is not as flat as the old one, but I wouldn't see that as drawback as you can really charge the speaker from any USB-port now.

Designwise not much has changed compared to the predecessor. Appart form the different color they still look pretty much the same, but the new one has the edges chamfered now. This little details does not only feel much better than before, but it also give a more refined look, together with the rubber seal of the speaker at the grille-side it looks much more coherent now.

But also the side ports are not simple holes drilled into the aluminium body, but rather an own unified element. These might be small details, but they are definitely a big improvement. I think that the old version looked and felt already great, but the new one especially the dark version even tops this.

The top control area remained the same but was simplified with less buttons. The aux and mute-buttons are missing now, instead both volume buttons frame a new center function button. This button has many functions and can act as track-control, something the old Soundlink Mini didn't have, and it can also control the built-in handsfree which was also missing before.
For controlling music playback double press will take you one track forward, while tripple press will take you back. A short press will either start or stop playback. You can either start calls by keeping the button pressed (and activating Siri) or reject calls and even jump between calls etc. Lots of functions possible through a single button.

At the bottom of the speaker you can still find the same big rubber foot that absorbs any unwanted vibration of the speaker well. Underneath this foot you will find the battery, attached by 4 torx-screws just like before. The battery is still of the same type and delivers 7.4V with 2330mAh, but I was quite surprised that it is not that easily exchangeable as before, because the contacts are soldered through a wire to the circuit board now. You might still be able to swap batteries with some tinkering but it is not a one-handgrip procedure as it was before. A pity and not quite logical, as a user replaceable battery is always a big plus for any portable speaker, now if this feature has been cut, a big advantage over most other speakers was robbed with the Soundlink Mini II. But Bose will hopefully have their reasons for this step.

Apart from that not much has changed with the general appearance. The Soundlink Mini II just feels like the old one with the same weight and heft, just slightly more refined thanks to the chamfered edges and a slightly different structure of the anodized aluminium body.
It feels much more solid and premium than the JBL Charge 2 for example, which doesn't feel cheap but gives a bit of a toyish impression when directly compared.

The Denon Envaya Mini is even slightly smaller than the Bose, but longer at the same time, overall cubature is more or less similar between both. Altough the Denon feels extremely well made, the Bose just gives you that extra feel of having something expensive in your hand. But I would not hesitate of tossing the Denon into my rucksack, while when I did with my Soundlink Mini the speaker grille immediately got a dent...
The new Sony SRS-X33 might have become smaller than the old X3, but it is still larger than the Soundlink Mini II, and won't give you any premium feel either.

On looks alone the Soundlink Mini II is extremely good looking and seems to be well made. But I wouldn't want to use it in an outdoor enviroment without any additional protection. It is not rugged in any way, although the silicone sleeves available as extra might help a little bit, but the front and back grilles will still remain totally exposed and are quite prone to scratches or dents. Neither it is protected against water or splashes and I would rather avoid using it at the pool where it might become wet, while the Denon Envaya Mini should be perfectly protected.

The most obvious changes compared to the old Soundlink Mini appear when you turn on the speaker for the first time. A voice will guide you to select the correct language and after setting your language it will tell you that the speaker is ready to pair. The voice prompts are exactly the same as in the Soundlink Colour. Of course you can also disable them, and although I don't like this speech-synthesizer voice much, it really helps if you intend to use the speaker with many different Bluetooth sources. The Soundlink Mini II is the next and only speaker after the Soundlink Colour which allows for an easy and comfortable pairing of multiple devices or switching between them. The Soundlink Mini II supports multipoint pairing to 2 devices at once, when the first device stopped playback the second device can start playback immediately, they cannot take over playback or steal it from the other device as it is possible on the JBL Charge 2 for example. Still pairing works so much better on the Soundlink Mini II than on any other Bluetooth speaker I have tried so far. After powering on it will tell you the current charging status of the battery and then it will automatically connect to both recently used devices with the voice telling you which devices are currently connected. If you want to connect to another already paired device instead, you don't need to dig into menus to disable Bluetooth on the first devices or brake the connection in some other way, by bringing the devices out of reach (don't laugh, this is how my mother always dealt with this problem) but simply press Bluetooth-button on the speaker again and the voice guide will tell you the next device in its list. If this is not the device you want to connect to, press the button again as long as the disired device is called then after some seconds the speaker will automatically try to connect to this device. If the device is not present or reachable the speaker will tell you that it cannot connect and you can repeat the whole thing with another device.
It might appear logical and simple, but only Bose really figured it out how to make the whole Bluetooth-pairing and connection procedure as simple and hasslefree as possible. I was already quite excited about this feature on the Soundlink Colour and decided to replace my mother's Soundlink Mini with the Soundlink Colour, as she always had problems with connecting to the right device, either the Soundlink Mini connected to her iPad instead of iPhone or it didn't connect at all.
With the Soundlink Mini II Bluetooth connections finally become as easy as with the Soundlink Colour and much better than on any other speaker I have tried so far. The Denon Envaya Mini, the JBL Charge 2 etc, they all might support multipoint pairing, but they never connect to 2 devices at once on their own, besides they always try connecting to the latest devices only by simply ignoring any other already paired device. The only way to connect from other devices is to dig up the menu and select the speaker manually from the list.
The Soundlink Mini II can remenber up to 10 different bluetooth devices, which is plenty and thanks to the unique switching ability you can cycle through all of them with a simple button-press.
The only drawback with this cycle-mode or switching-mode is that you will lose your multipoint connection to both currently connected devices. If you are for example connected to your iPhone and iPad at the same time, but instead of the iPad want to connect to your Notebook and start cycling through the whole list, as soon as the notebook is finally connected both iPhone and iPad won't be connected anymore. You will have to reconnect the iPhone again manually from its Bluetooth menu. This is at least what I have experienced.
On iOS devices volume control is mirrored between speaker and player. You still get all 100 volume steps when controlled directly through the speaker, or you can also control the volume through the volume buttons of your iPhone and will get 16 dedicated steps. Fortunately volume control is rather linear instead of what JBL is doing with the Charge 2, where the first steps manage to double the loudness until the jumps become finally smaller above the 5th step.
Another feature inherited from the Soundlink Colour is the ability to disable autopower off. Some owners seem to use their speakers in a stationary way. But the old Soundlink Mini shut off on its own after 30 miuntes regardless if it was running from battery or AC-power. Now with the Soundlink Mini II you can disable autopower off if the speaker is connected to AC-power. It will still power off though if running from battery and it would power off anyhow when the battery became empty...
So good news for all those who want to use the Soundlink Mini II as a kitchen radio permanently turned on or even as an alarm clock, although what a big waste this would be to use it just in that way.
Battery life is claimed to be improved with up to 10 hours (vs. 7 hours of the old one). As both still use the same battery any real changes must be rather based on some internal optimization. To see if there is any difference I let both play at their maximum volume with the same playlist to see when they will turn off. The Soundlink Mini II managed to play for exactly 3:25 until it turned off on its own, my own Soundlink Mini played for 2:55 hours. Just keep in mind that the battery of my Soundlink Mini is close to 2 years old, so there will be probably some loss of capacity, with this taken under consideration I am not really impressed with the battery life of the Soundlink Mini  II, it seems to still be hardly any better, the improvement is less than 20% despite having a completely fresh battery to begin with.

Now let's check the most important part namely if the sound has changed in some way compared to the previous model. First for all those who have not heard any Soundlink Mini so far, although I really doubt there will be anyone, let me give you some details about the general sound quality. If you are used to the sound you get from a Jambox, a JBL Flip or some other similarly compact speakers, the Soundlink Mini II sounds much more full-bodied. As long as you don't crank it close to maximum you really get the impression as if you were listening to a much larger speaker. Although both are tuned slightly differently, the Soundlink Mini II sounds pretty similar to the much larger Soundlink III which is no bass-slouch either, it is just when the Soundlink Mini starts struggling at levels above 70% that the Soundlink III is still going strong, but at normal levels I sometimes even preferred the sound of the Soundlink Mini. That being said the Soundlink Mini sounds more mature than many other even much bigger speakers including such models like TDK A33, B&W T7, I am not even mentioning the UE Megaboom here etc. You just have to be aware of the limits and that the sound starts to deteriorate at higher levels with some stronger bass reduction and noticeable dynamic compression.
Despite having quite a pronounced presence-region above 2kHz the upper treble area is rolling off much too early resulting in a muffled sound as treble above 12kHz has a very steep cutoff. If treble extended higher the sound would be perfectly in balance together with the obvious bass-boost, but as it is now the Soundlink Mini II simply sounds too bass-heavy most of the time as if it was playing behind some curtain. It is still acceptable, as long as you keep it aimed directly at you, but listen from some angle and there will be no treble at all albeit the presence region below will still give you the impression of some clarity which many might confuse with real treble. The Soundlink Mini sounds clear even off-axis, but it is totally missing any upper treble sparkle. You probably won't hear this when you are over 60, but any teenager will notice the tendency of the Soundlink Mini II to sound dull. Many will prefer the stronger treble boost of a Sony SRS-X33 or JBL Charge 2. The Bose Soundlink Mini II might appear even clearer sounding than the Denon Envaya Mini, although the Denon extends much higher, but the Denon has no obvious boosts, it is tuned relatively flat, while with the Bose I have the impression as if the boosted presence area is there to compensate for the missing upper treble.
The Soundlink Mini II doesn't sound bad and I prefer it much more over a speaker that has no bass at all like the UE Boom or the JBL Flip, it is just that it could get away with some better treble extension. This would make it sound much more balanced and pleasant to listen to than it is now.
Let me give you some details about the changes in sound compared to the old version or if has changed at all. Yes it has changed indeed, but the changes are hardly noticeable. You won't hear any difference if you don't have both devices in front of you for a direct comparison. Anyone who hoped for some improvement in treble or whatever will rather be disappointed, it is still the same sound you are getting here. The only thing Bose adjusted is that they took away a little bit of bass. The new Soundlink Mini II does not sound that overly bloated as before, but the difference is really marginal. It is maybe a 2dB reduction over the entire spectrum up to 500Hz. There is more reduction at lower levels and less reduction at higher levels. Many complained about the sound being too heavy and thick at low levels and Bose seem to have this corrected, although I really think that it is still very heavy sounding with the bass having a tendency to drone out the mids. The high amount of bass wouldn't be such a problem as it doesn't have any resonance and reaches really low, you get some response well below 60Hz at low levels. Bose seem to apply a kind of loudness compensation as the bass is boosted more and more at lower levels and reduced at high levels, this makes the speaker always sound full and mature, the problem is rather that the bass becomes a bit uncontrolled at levels above half. Despite the slight bass reduction with the new model there is still some distortion and droning noticeable with particular recordings. Something you won't get from the JBL Charge 2 or the Denon Envaya Mini which play the same songs much more controlled. I cannot list the Sony SRS-X33 here as this distorts even more than the Soundlink Mini II, and sounds really much worse than either of them if higher levels are considered.
While there were quite big changes in sound with every generation of the bigger Soundlink models (Soundlink I, Soundlink II, Soundlink III), Bose didn't really change anything this time. The bass reduction I am hearing might also be some sample variation between different units or simply the missing of any "burn in"-period for the new model.

Let's see how it performs from the measurements. Here you can see the entire volume-range of the Soundlink Mini II with 10 steps between each measurement.

I picked up 3 measurements of the Soundlink Mini (grey) and Soundlink Mini II (black) to compare both directly, the lowest one was taken at 40% the one above at 75% and the top one at their maximum volume. As you can see they still measure pretty much the same, the only real significant difference is the overall louder bass oft the old Soundlink Mini, any other differences could be also caused by slightly varying placement for both speakers or simply the result of a stiffer cone suspension of the newer unit
Of course you will be interested how the Soundlink Mini II fares against all the other current contenders, therefore I measured them all at around 70% of their volume, where all of them are already starting to apply some bass reduction.
First let's compare the Soundlink Mini II with the Sony SRS-X33 (red). You can see that the Sony has similarly deep bass as the Bose, but the frequency dip in the upper bass region is starting to become pretty obvious at this level, at the same time treble extends quite a bit higher on the Sony:

Compared to the JBL Charge 2+ (green) the Bose shows a louder overall bass which is reaching even slightly deeper, but the strong bass and treble peak of the JBL is clearly visible and manages to give the JBL even a punchier sound especially at higher levels where the JBL retains more bass than the Bose. What's not visible from this measurements is that the JBL has no distortion at this level yet, while the Bose already shows more than 20% THD close to 80Hz:

The Denon Envaya Mini (blue) measures relatively flat and doesn't have any of Bose's boosts, but the bass of the Denon doesn't quite reach as deep, still the Denon will give you a much more natural and realistic sound than the Bose and it has better treble extension as well.

I also prepared a short video demonstrating the most obviouis changes between the old Soundlink Mini and the new model but also differences in sound if you are able to discern any:

The Soundlink Mini II is definitely a big improvement over the old model in many aspects, it just doesn't improve on sound. If you already liked the sound of the Soundlink Mini, you should love the Soundlink Mini II as well, especially in regard to all the new features included now. It you didn't like it so far, it is unlikely that you will like the new model, as both still sound pretty much the same. Nevertheless the Soundlink Mini II will probably still remain the market leader for portable Bluetooth speakers and in reality it is a great speaker with all necessary functions built in: It can be charged through USB now and it has handsfree included as well. Bose doesn't do things by halves and everything they included into the Soundlink Mini II works really well and much better than on most other competing speakers. I really love the easy and reliable connection to many different Bluetooth sources. We can argue about the sound quality, but I wouldn't call it bad, it is just that it could have been improved or finetuned a bit within the last 2 years. Obviously the selling success so far showed Bose that the main part of their customers are already satisfied and they decided not to change anything. If you like the heavy Bose tuning and still don't own the old version go out and grab the new one, as it is an excellent portable speaker, just handle it with care and don't throw it into the water, but on sound quality alone you will be definitely much more satisfied than with anything UE is offering so far. If you already own a Soundlink Mini but were longing for some more hifi-like sound tuning, you might still want to wait a little bit until the RIVA S appears, because from what I heard so far I think this will be finally the portable speaker all of us audio geeks were waiting for. Alternatively both JBL Charge 2 and Denon Envaya Mini are worthy alternatives, the JBL Charge 2 with a more punchy sound and better battery life but also the ability to charge external devices, while I would call the Denon Envaya Mini more natural sounding than both the Bose and JBL. It all depends on the music style and on your taste.
It is great to finally have the choice between such high quality portable speakers and Bose led us the way to this. If not the Bose Soundlink Mini, we would still be satisfied with a Jambox or UE Boom paying 200$ for that junk without being aware that it could become any better...

  1. Hopefully this isn't a double post; Google problems :)

    The user manual specifically states:

    "A fully charged battery provides approximately seven hours of use at maximum volume. The rate of battery discharge varies with the volume setting."

    Do you have a representative/contact at Bose that can be asked about this? I would call it extremely inaccurate at best, misleading/deceptive marketing at worst. 3:25 is...well let's say less than 50% the battery life stated. :)

    That said, waiting for mine to ship and will of course test as well! Thanks for the great reviews as always!

    1. The battery is just 2330mAh, it would be very unrealistic to get 7 hours out if it at maximum volume. The JBL Charge 2 has 6000mAh and plays for 6:30

    2. I don't disagree on the battery rating, but this did not stop them from making a rather poor statement; having worked in marketing, my experience is that you shouldn't make empirical claims like this, especially if they are that far off base :) Legally, "approximately" usually means something like "very close to an actual accurate answer in mathematics". Just be very interested in how they would speak to that claim. Anyway, it is merely curiosity; obviously someone's satisfaction with the speaker and battery will be subjective to their own experiences.

      My carbon ships tomorrow and will test against the Envaya Mini, but also still excited about that Riva S. Does the buying cycle ever end? ;)

    3. B&O states 24 hours for the Beoplay A2 and it died after less than 1 hour at maximum volume. I prefer testing them on my own than trusting some vague claims.
      The RIVA S could be really a perfect mix of all of them. It has a nice treble extension better than all of them with a nice neutral sound like the Denon but at the same time punchy deep bass a the Bose but not as bloated and it still sounded perfect at maximum volume without any hints of distortion or compression while the Bose is not really enjoyable at levels above 80%

    4. I was going to make a comment about that, that the Bose shouldn't really go over 80% anyway :) And I agree one should test themselves, I just dislike on principle people making poor claims :( It's one thing to say "up to", but another to say "approximate".

      And Riva is a great company, probably the best customer experience I've ever had. I do trust their claims and dedication :)

    5. I had a dispute with some other Youtube reviewer because he claimed the Megaboom would play for 12 hours at maximum volume. I tested mine and didn't even reach 4 hours. As he insited in his 12 hours but I had already sent mine back and couldn't do another test, I thought I might have god a dud or something... but 6 hours at maximum volume like the RIVA Turbo X is already pretty good, 12 hours would be classleading and the battery inside the Megaboom just doesn't seem to be that great.

    6. sorry, he even claimed 17 hours at maximum!

    7. The Turbo X at max+turbo for 7 hours would shake my walls down! (Unfortunately that's when it also sounded best, at high volume.) Glad to hear from your review that they tuned for lower/mid volume on S, and battery should reflect that. Darnit, now I just want them to ship!

      I still really like the A34, but after a while the bass does start to stress your ears (unless the battery dies first).

      Can I ask, do you use any bass heavy tracks (like freely available Girl Talk) when doing your sound and battery testing (not on video)? I know you are limited in what you can use on YouTube due to content licensing, but a lot of what I hear like (Freesia?) is more nuanced and less dance/rock which tends to be what plays at loud volume at parties around here :) Just so I can understand what other kinds of music you test, to help interpret your reviews. Maybe a Spotify playlist you could put up? (Plus I kind of like some of the music you are helping me discover!)

    8. How long does your A34 play at higher levels? I had a A33 at home recently again in order to record it for my database and the battery was already that weak that it didn't manage to play for 1 minute at low levels.
      Currently I use a mixed playlist of Konstantin Klashtorni for my maximum volume tests:
      This is more a relaxed Smoothjazz, but his tracks are mastered pretty fat with lots of bass and are also quite loud. I usually put them in my cellar and let them play until they die. I can still hear the music upstairs with the louder speakers, and if I played some heavy rock or dance stuff I would probably get annoyed pretty quickly ;-)

  2. It’s interesting that the measurables, as well as your Youtube sound tests, seem to have an overall lesser degree of bass. This is because a friend of mine got one and his appears actually to sound…bigger. Does it handle lower actual frequency than the original Mini does?
    I also am of the opinion that all of us audio guys know that to expect a reference level sound out of Bose is impossible. That’s not Bose’s M.O. Bose is in the business of creating the most pleasantly listenable sound in small packages, and they have a general sound signature which is designed for the greatest variety of ears. If you like the Bose sound signature, you’ll like most of Bose’s products. I do like that sound signature, and I sometimes think there is some active processing because…well, outside of the bass, everything I play through it appears to sound linear. I certainly disagree with your claim of lost highs, unless you happen to be sitting behind the speaker rather than in front of it, at which point you’re facing the bass driver anyway. Measureables not withstanding, I have never complained that the bose could sound, in any way, dark. This is no different than some old boom boxes I’ve seen from companies not named Bose. Speaker placement is important.
    The interesting part of your review is that things you consider problems, I consider features. The only way to pair to two devices would be to pair them on startup, or repair from the device end for instance. As a blind user, I like this, because it gives me absolute control over what goes into the speaker and what doesn’t at any given time. Especially given the fact that if I’m paired to my phone, I still want my laptop to be able to talk to me. If both are paired and one isn’t able to interrupt the other, then is there a way for it to signal that one is playing and for the other device to just play through its own speakers, or does it just go to null and you have no idea. We’ll certainly find out.
    Same with the Bose’s extreme directionality. I remember being at a barbeque with my SoundLink mini, which was not the primary source of music. I was sitting at a table with my Grandfather and we were listening to a game on the mini, at a moderate volume so as for every word to be heard clearly over top of the gathering. Those outside the speaker’s direct fire could not hear this, and I saw that as a marvel of engineering that something could be so intelligible, yet directional at the same time. The SoundLink mini isn’t designed to be anything more than a personal listening speaker…I have used it very well to do more than that, but in very controlled environments where I could use the room’s acoustics to help out the speaker’s shortcomings. Classroom presentations come to mind, although if I were doing that regularly, I’d buy something larger.
    And one last point…The RIVA X…How much will it cost? That’s kind of the kicker here, as Bose’s product is cost competitive with its class. Will the RIVA be the same?

    1. There might be also some sample variation playing a role here. My own Soundlink Mini sounded considerably clearer than all other units I have tried. The tested Soundlink Mini II seemed to be on par in clarity, but had less bass. As my unit is close to 2 years old, they might have changed manufacturing in the meantime etc. I had also noticed a difference in sound between various Soundlink I units.

      Regarding lost highs: The Soundlink Mini has some boost above 2kHz, this can mask the missing treble above 12-14kHz, because in fact it is non existing with the Soundlink Mini. I hear well above 16Khz still, although over 40 years old, but I hear that the upper treble part is simply missing with the Soundlink Mini, it becomes even worse off-axis.
      When I heard the RIVA S it was a night/day difference with the smoothest treble I have heard so far from a portable speaker that small. It extends way beyond 18khz without any narrow peak like the JBL charge 2 for example which has a strong metallic character.
      The RIVA Turbo X is 349$ everywhere, the RIVA S is aimed at 249$ how I was told, but with an own carrying bag included.

  3. Did you not find the sound cuts out a lot?

    I bought the soundlink mink II yesterday and unless it is within a metre or so of the paired device without anything between them it will cut out. If left alone in a room it will play quite happily but if you walk past it will cut out. If it's less than 4 metres away and you're vaguely between it and the paired device it will cut out continuously.

    Just wondered whether anyone else has had this problem or if I have a dud one?

    1. I just returned an exchanged Soundlink III, due to the audio cut out issue. After a great deal of troubleshooting, I isolated the issue to wifi. If my iPhone and iPad were connected to wifi and I used the Internet or Pandora, the sound would cutout and change pitch, but would return to normal. If I turned the wifi off on both devices and used the cell signal on my iPhone, I could not duplicate the issue. I have a couple of videos (audio only) and a voice memo recording of the issue.

      I must say, I am pretty disappointed in Bose for this issue. I am searching for another speaker. The comment that I am replying to is steering me away from Bose, which hurts, as I really enjoyed the audio quality when the speaker worked properly.

    2. It's plain easy. WiFi and Bluetooth are using the same 2.4 GHz freq and in modern devices, for cost cutting, power management and size reason, they use the same antenna and modem for it.
      This is why I can't get good wifi speeds when I use a bluetooth speaker with my laptop or phone, and this can cause interferences and likes...

  4. Ok, this is news to me... I noticed my Mini II suddenly wouldn't turn on after sitting a couple of days unless I plugged it into power. (Battery was still fully charged, it notified me.) Weird, I thought. Then it did it again just today.

    I called Bose and they said that was "Shipping mode", and it was designed to protect the battery by shutting it completely off after 48 hours. They also say there is no way to change this mode. It seems very odd that this isn't talked about more widely if in fact this is standard behavior. Surely tons of people are like me and just leave the Mini sitting somewhere in the house not plugged in for a couple of days? Just wanted to see if anyone here has experienced this behavior. The rep on the phone even said "yes I know it can be inconvenient, like if you leave the house with the speaker and don't bring a power cable and won't be able to use it". Seems like a pretty big design flaw?

    1. Oops, a quick edit. I see the manual does say "24 days of no power". That's a bit different than the 48 hours the rep claimed.

    2. I encountered the same issue somewhat inconsistently. When I left it unplugged for a couple of days, I could usually turn it back on, but there were a couple of times when it would not turn on just after one day. Very strange and annoying. The last straw for me were the indicator lights (battery and bluetooth connection). They did not turn on no matter what I did (when unit was unplugged). I ended up returning it today.

    3. They replaced mine and the new one seems to be working fine as long as it's left with some power in it. See the comment below about being at 10% or less (which somehow I missed in the manual, unless it wasn't in the original one they uploaded) and it being more aggressive about going into shipping mode. I don't mind it so much if it's only at 10% or less, since I'd need to charge it almost immediately anyway.

    4. I am having the same problem with mine mini 2. After couple of days of no usage, It would not turn on unless I plug it to power. It still has battery 70% or more as it notified after turning on. I guess some units do not care about 10% limit and just goes into shipping mode after 2 days of no usage.

      How is your new one? Have you tried not using it for 3-4 days and see it turns ON or not. If you did not have this problem in new one, I think I will ask Bose for replacement.

    5. It has seemed fine so far; I will let it sit for another couple of days and see what happens and let you know. Ping me back on here if I don't remember to respond :)

    6. I tried to do this test by not using it for 4 days. On 5th day, it worked well. Not sure whats happening. But in last 2 months, this has happened with me two times. So there is something. It is going in battery protection mode when it should not.

      I don't want to get it replaced if new unit will have same problem.

    7. Had that issues since I purchased it 2 months ago.
      I had a long chat with Bose regarding that but they are not admitting anything.

      Manual states that should only happen after 24 days and/or when the battery is below 10%.

      So either the clock on the Bose MCU is running fast or the A/D (Analogue to Digital) is defective, or software bug or software feature.

      If software bug/feature Bose should consider changing it.
      If it was hardware then it makes sense they are stating it's going into "Shipping Mode", no where in the manual states anything regarding shipping mode.

    8. please try update the firmware

  5. From the bose Manual:

    "When the system is unplugged and unused for three days with a remaining charge
    of less than 10 percent, it enters battery protection mode to preserve battery
    power. To reactivate the system, connect it to AC (mains) power (see page 10). "

    Your Bose Soundlink Mini II's A/D function is not working. My BSM II is the same.
    Talked to Bose and they said it's a "shipping feature", more like covering their asses...

    1. See comment above :) The replaced one seems to work fine so far, but did do the 10%->shipping mode thing on me it seems. I don't guess I mind TOO much since I'd plug it in if it was at or below 10% anyway. Having seen what happens to lithiums that get completely discharged, I guess this is an ok compromise. Still waiting on the JBL Xtreme to be my likely replacement anyway.

  6. Hello,

    I believe the bass is more, because it's designed to run in an open space.Try it out and see for yourself.

  7. "Handsfree" what really it means? And also is this same as other bluetooth speakers that can be turn it on or off by using the paired smartphone? If it is then, it's a good feature so I don't have to get up from bed to turn it on.

  8. soundlink 3 or sounlink mini 2?

  10. The lights on my speaker (battery indicator + bluetooth) turn off and do not turn back on.
    I've noticed this when the battery is below 50%.

    I'm hoping this is this a feature to save battery however I am curious if anyone else's speaker does the same thing?

    1. This comment has been removed by the author.

    2. Same happened to me but it still has 70% of the charge, i wonder if its a feature that can be disabled because its pretty annoying not having the lights when i still have a lot of charge and am not interested in saving battery. I just plugged it in for about ten minutes and now the lights work, really wierd, hope it doesnt happen again. Oh and mine is about 2 weeks old and haven't even finished the first charge of the battery and haven't even taken it off my desk.

  11. Just the same as you. After one week of perfect working, lights turn off even on the base/cradle. The speaker connects with all the devices perfectly, but no lights and no voice battery load percentage warning as it used to when switching on/off. When I switch on the device only says ready to pair. On the cradle no lights so I don't know if it's charging or not.

  12. Bought soundlink mini 2 for a month ago. It worked fine until two days ago. Battery went below 40% and I tried to charge the thing over night , but it wouldnt do that (no matter if you use the platform or bose itself for charging). Instead the battery charge decerased and now only the red light is blinking. Other have had same kind of problem. Is this some kind of product bug?

  13. is it very difficult to replace the battery on the mini2?

    1. I don't think it is meant to be replaceable by the end-user, as the wire is soldered to the speaker.

    2. I don't believe it's soldered. If it is then it has to be a manual job because of how it's assembled and we all know manual labor is expensive so they want to avoid as much of it as possible.
      Most likely it has a connector at the battery end and it's very easy to disconnect (at the picture cable is positively soldered at the speaker end). You're not just confident enough to go actually unplug it ;)

      They can have various reasons to replace the old connector with something with an intermediate cable. Perhaps they've had a great deal of warranty claims because of solder fatigue because the old way potentially put stress on the circuit board where the connector is located. The easy way to deal with it beside making sure tolerances and assembly and user handling don't put too much stress on the connection is simply to relief stress by using an intermediate cable.

  14. Thanks for sharing it. Actually i had no clear concept about it but now i am clear about it. Also i want to know more from your next blog. Thank you.

  15. Your blog is so nice and informative thanks for share. Nice post! I really like this one and I am happy that I stumbled upon this page while looking for some other information.

  16. I have the same problem: two days off. 60% load and will not start. Dammit!

    Amazon speak of an update with a new firmware. There is a link, but do not report how it is installed. A fucking disaster. I'll get in touch with BOSE-Spain. And I will report.

    I also had twice the problem led off. I disconnected the Aux cable, reconnected, press power and everything returned to normal.



    2. This comment has been removed by the author.

    3. Thank you! But weeks ago I downloaded the firmware, however, there is no instruction on how to install it. Nobody tells you how to do it!

      BOSE-US no information on how to install the firmware.

      BOSE-Spain have no idea of the existance of this firmware.

      Definitely, a disaster of post sale service.



  17. Bose-Spain tells me I should carry the Bose Mini II to official technical service BOSE.

    I do not install the firmware, it is the technical service which is responsible for the "repair".



  18. I recently purchased this speaker. I prefer crisp treble of Charge 2 but simply the design and build quality of Bose is much better for me. And got it for £114 So I think good price.

  19. I have teh same problem here in Germany: 5 days off. 60% load and will not start. Did tehe firmware update help or have i to send the speaker for repairing?

  20. I sent mine to repair and after 3 weeks they gave a new one.

  21. Alex, I also experienced LED off altogether. The strange thing is that if AUX is connected, if I unplug and plug back AUX jack, everything returns to normal. I also happened via Bluetooth, and, as Jack not had a hand, put it to charge an instant, and everything returned to normal. This half dozen times I happened since I bought ...

    Regarding the update, I have not dared to do it now, even though it seems easy to make. But I am afraid that something goes wrong, then the BOSE look even worse ...

    However, the speaker is sensational; I think it sounds better than the video of the test, but much better : the bass, midrange and treble are more detailed and have more presence than on my recordings of the test videos.

  22. Awesome review thank you. I was given the SoundLink Mini II as a gift and I would vary between loving it and thinking wow -- it's really flat as you described above. I am closer to 50 than 60, and my ears hear the issues at high frequencies.

    Being an audio buff myself, I had to delve into this and discovered what the major issue is with this speaker and why I like it at times and not others.

    It had wickedly bad off axis response at high frequencies. Not just a bit bad .... wickedly bad. Hold it in your hands pointed at yourself and rotate it. Anything beyond about 15 degrees off axis and you notice a serious drop in the high frequencies. It makes placement difficult.

    I find an equalizer app can solve a lot of this issue.

    I suspect the underlying issue is the drill. I will be taking it off to see if I am right.

  23. Great! I'll bring it for my own. Nice suggestion.

  24. The Mini has too much bass for my taste, but I found a way to control it somewhat. Take a look at the first frequency response chart above. The bass is boosted at lower volume settings, but not so much above 70% or so. This is typical of the Loudness Contour circuit that emphasizes bass at lower volumes.

    You can use this Contour feature to control the bass. Just turn the volume way down on the music source. Then set the Mini volume near the top and use the source device to control your level. There will be considerably less bass.

    When the bass is not so loud, it is easier to hear the treble.

  25. Fantastic review Oluv - many thanks but one question : with the auto power off feature disabled (I would be powering the speaker from the mains supply all the time), does the BT still switch off after 5 mins of no device pairing as the series I unit does? The reason I ask is I love the audio quality and low profile but I need to place it hidden out of the way on the top of a kitchen wall going up a stepladder to keep pressing the BT/power wake button is a non-option :-) Many thanks, Nick

  26. Great review. It must be said that there is a lot of mechanical engineering in this product...How do I come to that conclusion? Well, basically, I stripped out the internal Bose amplifier and powered it directly from an external amp with no equalisation. The response curve mimics that of the Bose equalised amp with the exception of frequencies below 200Hz. I have had to apply approx. 15db boost to the lower frequencies to get a flat response down to 65Hz. This was achieved by simply applying a boost at 60Hz octave on an audio analogue audio equaliser. The sound is still very powerful. So, congratulations to Bose for getting the mechanical properties of the drive units, passive radiators and enclosure so right. I think most manufacturers rely too much on DSPs to correct the shortcomings.

    1. what's so impressive with a speaker needing 15dB bass boost while not being able to produce anything above 10khz?

    2. 10 kHz? That is so weird. I equalize sounds in the band 10 - 15 and 20 Khz, and BOSE plays them "perfectly", within their limitations. I have never seen a full range driver with no serious limitations, or above or below the audible spectrum.

      The B & O Play A1 that you quote, has the great advantage of porting a tweeter independent of the Media / Bass driver. That is a big asset in favor of BeoPlay. The bad, the really bad, is that it has a 2.200 mAh battery junk, with a serial configuration, which gives you a miserable runtime. The BOSE with a similar battery and the same configuration (in series), provides a significant increase of runtime. Which makes it much more operative.

      As you can see, the engineers of B & O have been very stupid and stingy when it comes to thinking about the type of batteries. It is incredible that there are still 3,400 mAh batteries on the market that these gentlemen want to continue selling products that are certainly deceptive. Remember that B & O announces a 24 hour runtime: they should be shot at dawn for saying that. :-)


    3. the A1 can play for more than 2 hours at maximum being twice as loud as the Bose, which manages 3:30 at maximum with a totally compressed and distorted sound. The A1 at comparable levels to the Bose will give you twice the battery life.
      And not sure what you are hearing, but the Soundlink Mini rolls off below 10khz already, there is little response above and if boosted you would just boost intermodulation as well which is already pretty nasty. No excuse for the bad driver design, check the JBL Flip 4 which has clean response up to 16khz and way better controlled sound. It has just no fake bass boost at low levels as the Bose.

    4. Oh, yeah, I'm pretty sure of what I hear. In fact, the BOSE Mini II is not a waste in the treble scale, but for that are the equalizers of the source. I do not know of any loudspeaker (bluetooth or no bluetooth ) in the world that does not need some kind of equalization to get them the best possible sound. If you notice a lack of treble in the BOSE, I agree, but then, equalize the source and there you will have them.

      The Bose MiniII is perfectly capable of reproducing frequencies above 18KHz when the source equalizes only 1 or 2 db. You can check it on your PC with the GOM AUDIO application equalizer and the corresponding files in wav format.

      Yesterday I listened to a demo at the B & O Play A1, and with Michael Jackson's legendary track "Billie Jean" at a very moderate volume, and... where is the presence of the bass (Louis Johnson) that marks the beginning of the track? It simply is not, a real disaster. A real disaster for more than 200 Euros. I can not live without heavy bass, but balanced, of course. And the B & O Play A1 at very low or low volumes, does not deliver them ...

      Yes, it is a more balanced speaker, with better response without equalizing than BOSE Mini, of course, but... but no. ;-)

    5. EQ, you just said it yourself, and the A1 has an own EQ within the app, you can make it twice as meaty as the Bose at very low levels. Funny thing is, that the A1 reaches down to below 50hz, while the Bose has just some horrible boost. this is a joke you are saying here. The A1 and Soundlink Mini are worlds apart, it is as if you were comparing a fiat500 to a porsche.

  27. The size of the unit as a whole is the reason which makes it impressive. It produces an excellent full range performance. Full range being 100hz to 10khz. I'm from a generation of over 40 decades. 15db bass boost into a drive unit that size 40 years ago...unthinkable!

    1. Try the Riva S then, which holds up much better until higher levels with hardly any compression or intermodulation like the Bose.
      I am not even talking about the Beoplay A1 which makes the Bose sound really funny.
      Bose were pioneers trying to sequeeze out big sound out of small speakers, but in the meantime they are completely dated and overpriced. There was no improvement from them during the last 4-5 years anymore.

  29. Hi oluv, could you do a sound comparison between bluetooth and aux? I feel that by using the aux port, it losses some bass compared to bluetooth.
    Thank you in advance.

  30. Hi Oluv,
    I watch all your videos and they are simply great which help everyone decide the speaker for their own taste. I have a question, can we pair two Onyx Minis or two Flip 4s for a true stereo. I am planning to buy one of these two and please help me with this. Or suggest me a Bluetooth speaker with great stereo separation.

  31. You can utilize this Contour highlight to control the bass. Simply turn the volume path down on the music source. At that point set the Mini volume close to the top and utilize the source gadget to control your level. There will be extensively less bass.great blog thanks for sharing

  32. Purchased soundlink small scale 2 for a month back. It worked fine until two days back. Battery went beneath 40% and I attempted to charge the thing over night , however it wouldnt do that (regardless of on the off chance that you utilize the stage or bose itself for charging). Rather the battery charge decerased and now just the red light is flickering.

    1. There is a bug in the battery management system. I use the speakers everyday and I constantly run into this problem. As soon as you try to charge it once the battery is below 50% (my guess) it won't charge anymore.
      So the only thing you can do is completely drain the battery to the point where it won't work anymore and wait 24h (this will reset the battery system - see shipping mode mentioned before). After 24h (do not try to do it earlier, since it will reset the 24h timelapse) you will be able to charge it again.
      Overall this seems to be a very stupid bug and I am sure this could be addressed by some firmware update, but Bose hasn't really acknowledged the problem yet. This is the only workaround that I have found. I hope it works for you as well.

  33. Good post, When I switch on the device only says ready to pair. On the cradle no lights so I don't know if it's charging or not. thanks for sharing video link.

  34. The sound link mini 1 sounded better than 2
