News: Finally! JBL Charge 2 - 1.4.1 firmwarefix


Finally with the latest firmware the JBL Charge 2 manages to be what it should have been from the very beginning back in September, when it still suffered from teething troubles.
Until now I couldn't fully recommend the JBL Charge 2 without reservations, as the issues were too disturbing and it remained rather a "also-ran" speaker among all the others.
In the meantime there was lots of discussion on Youtube regarding all those problems with many users complaining about their units still to distort, while others claimed to have no problems at all. There were theories established about serial-numbers which would indicate when the unit was manufactured and when it would be without issues. I was enjoying all this similar to reading a crime thriller.
Then finally someone from Japan came up with an undocumented trick to check the currently installed firmware on his JBL Charge 2. He finally claimed that only the latest firmware "1.4.1" would fix all problems, while all firmwares below suffered from this or that DSP-issue.

To check your firmware you have to power on your JBL Charge 2 and be sure that it won't connect to any nearby Bluetooth-device. Now press the Bluetooth button and volume + button simultaneously and keep them pressed for some seconds to finally hear a nice female voice that will tell you the firmware number, something like that: "one four one".

If you don't hear "one four one", you should get your device updated. I own a "refurbished" version that I bought back in December after returning my very first unit from September, and while my current unit didn't have all these distortion problems of the very first unit, it was still close to unsable at lower levels during the first 4-5 volume steps. After checking my firmware it said: 1.4.0, therefore I decided to update my model as soon as possible.
Unfortunately Harman never planned to make the devices user-upgradeable, thus you should contact an authorised service center. I contacted Harman directly to ask them how to proceed and 2 days later I got their response where they told me the responsible center in my area. I already knew DEC Service Center in Vienna, as they are also responsible for Panasonic repairs and I had some repeated issues with my Lumix cameras or lenses. The next day I took my JBL Charge 2 and left it there for an update. After 10 minutes I already got it back with 1.4.1-firmware installed and had a chat with the responsible technician who was well aware of the problems.
According to him this whole thing was getting quite fuzzy, as there were many users who complained about the problems, but at the very beginning even the technician wouldn't acknowledge them. There was no statement from Harman either until January where they finally issued an official update-service. A special updater-software for 1.4.1 version was provided to all service centers with a time-limit of 1 week to be downloaded, otherwise a permission for a new download had to be requested again. Login has still to be done through some Harman server etc, so this whole thing still sounds a bit "obscured" for me and I don't understand that Harman didn 't even care to contact their customers to inform them about the update. I had contacted Harman several times about this, at the very beginning they suggested to return the speaker, when I asked afterwards if there would be any update, they could have at least responded now. Given the fact that the update was already out nearly half a year, while some new owners checking their firmware are still hearing "one three eight", this is really annyoing! They could have at least communicated it in one way or the other.
Update: Check out how you can upgrade the firmware on your own here!

But the most important fact is, that the JBL Charge 2 is completely issue-free now. I measured the JBL Charge 2 with my previous 1.4.0 firmware and measured it again after the update to 1.4.1, and what you can see from the measurements is that the first 3 steps were entirely screwed up with the old firmware (green) that was incapable of producing and clean output below 150Hz while with the new firmware (blue) it measures ok. Unfortunately the very rough volume-steps that were already present with the previous versions became even stronger now. The first volume step is louder now than it was before and the 3rd volume step is nearly as loud as the 4th step from the old version. So if you intend using your JBL Charge 2 at low levels, it might be a hassle to achieve the correct loudness as the first step might be too soft, while the second one too loud already especially when using an iOS device where volume control is mirrored between speaker and player:


The new firmware also seems to come with some minimal sound-adjustments. I matched the 5th volume step for both by pulling the old version some dB up, and as you can see the new firmware took away a little bass in the region up to 300Hz (the strong peak at around 75Hz remained exactly the same though) but usually you shouldn't notice any difference at all without having a direct comparison. The other slight deviations visible are probably measuring errors due to slightly different placement (again green firmware 1.4.0 and blue 1.4.1):


After the update I would say that the JBL Charge 2 is in the top-line of current portable speakers, with a great punchy sound at all volume levels, class-leasing battery life and a lower price tag than most competition, especially now after the new Charge 2+ has been issued. Thanks to the Charge 2+, the Charge 2 can be even found far below 100$/€ which is quite a bargain. Grab one, if you were still undecided.
Many will ask if it is any better than the Denon Envaya Mini? I would say yes, if the total package is considered, as the Charge 2 makes more fun, has a much more solid battery which can also charge other devices and meanwhile it also cheaper, while the Denon became more expensive. The Denon might have a flatter and more true sound, but the JBL fares really well with its obvious bass and treble-peak that both make it more consumer oriented.

If you want to know if the Charge 2+ sounds any better than the Charge 2, stay tuned as I will compare them both directly soon.

  1. I'm very interested in the Charge 2+ (the water resistant factor is important to me), so much that I've been waiting for your review/thoughts on it every since I got to know about it.
    I'm glad they've fixed what was wrong with the Charge 2 and that you're now finally able to fully recommend the speaker. Hopefully this means that the Charge 2+ will be the new king! I'll be looking forward to that promised comparison between the two top JBL speakers.

    1. on sound quality alone, there is no difference. the new one is neither louder nor different, the differences if any are negligible and could be also a result of some "burn-in" process.
      I also doubt that the + is really water proof as the rear ports are completely unprotected just like on the old version. if you want to save some money go for the JBL Charge 2. Mine got wet several times and I never had any problems with it.

      Delete
    2. Yes, you're right, I've read elsewhere that the Charge 2+ is exactly the same speaker as the Charge 2, but water resistant and with the previously reported problems already fixed. So, soundwise, it should be as impressive as the Charge 2 is now with the latest firmware. I need a good portable wireless speaker that I will also be able to use in my bathroom, around the pool and at the beach, so it must be water resistant (and not necessarily completely water proof like the UE Megaboom). You mentioning the fact that the rear ports are still unprotected troubles me a bit... But I've seen at least one video on YouTube where someone actually shows a Charge 2+ playing loud with water bouncing on it (thanks to the nice bass!). I've also read elsewhere (maybe from JBL themselves? I can't remember) that you can even rinse the Charge 2+ with running water, so I'll definitely need to confirm its water resistant properties. I don't expect you to dedicate much time to the water resistant ability of the Charge 2+ (since I know it's not what your priority when reviewing speakers), but I sure hope to read your impressions about its sound quality (expecting you to confirm that it remains as great as the Charge 2 with the updated firmware). But once you get a hold of the Charge 2+ if you could share some info on the water resistant side of things, I'd be more than happy about it!

      Nonetheless, if you think a regular Charge 2 could withstand a few splashes from the shower, I would go for one in a heartbeat (it's currently priced at 70 pounds on Amazon UK, which is a very nice price for it, I think)!

    3. I have a Charge 2+ at home thus i measured both and both measured exactly the same, I couldn't notice any big difference in sound quality either, they were virtually identical. Also design is exactly the same with exception of the front logo, but build quality etc is close to undistinguishable. If it was really water resistant they would have added some rubber-flap to protect the ports. The Boom, Megaboom, Infinity One and all other water proof or resistant speakers have the ports protected in some way. The only one without protection is the Fugoo, but this has special water-proof ports to begin with.
      I used my Charge 2 during rain, once a bottle in my rucksack leaked and the Charge 2 became totally wet, without any problems. Maybe they use a different material for the driver-cones, or there might be some water repellent cloth underneath the grille, similar to what UE is using on their booms, but both would have some influence on sound while in reality they both still sound the same. I think the Charge 2+ is just a marketing gag to get rid off the slightly bad reputation of the Charge 2. It is the same device again, with maybe slightly better sealing, but as the ports are still entirely unprotected I even doubt this.
      I definitely won't drown it under water as I will be sending it back. I expected some improvement over the JBL Charge 2 as there were claims that the + sounds more refined and louder, but both claims are not true. Therefore I'll keep my Charge 2. In Germany you can even get it for 88€ right now, it would be stupid to pay double the price for a would-be water resistance.

      Delete
    4. Ah! I knew it would pay off to read your thoughts on the Charge 2+! I'm disappointed with that "marketing gag" theory of yours, because, sadly, it makes a lot of sense. I will still be looking forward to your videos on the Charge 2+ performance, and I don't know how much they will charge for it in Europe (it costs 149 USD in the States, I think) but I will most likely get a regular Charge 2, instead, after what you said.
      Also, since you already got one, I didn't know you could get a Charge 2+ in Europe already, I thought it was only being sold by JBL themselves in the USA for now.

      Anyway, thanks for the heads-up about the Charge 2+ likely marketing trick, you might have just saved me (and others, I'm sure) a few bucks.

      Delete
    5. You could already buy the Charge 2+ from the JBL site 2 weeks ago, it costs 169€ right now:

      Delete
    6. Oh my, it's ironic how I tried to keep myself updated regarding the Charge 2+ release in Europe and it seems that I've totally missed it.
      That price... It's really twice as much the current Charge 2 price in Germany. That's... EXPENSIVE! Considering all you're getting extra is (allegedly) better water protection, it most certainly does not make the Charge 2+ look like an attractive purchase at such high price.
      The only good thing that I can see, for now, in acquiring a Charge 2+ is that you'll get, for sure, a Charge 2 with the most updated firmware, with all the bugs ironed out. Whereas if you buy, right now, a regular Charge 2 from Amazon or elsewhere I guess you could easily get stuck with an older and still buggy version of it.
      After reading your thoughts on the Charge 2+ and the Charge 2's updated firmware I really need to revise my purchase intentions.

  2. too late
    hi hi hi
    I had the charge 2 red

    I have a question-
    I will use my speaker for car and home use and rearly outside.
    charge and denon will cost about same for me, 10 pound difference.
    I like a warm sound but not to bassy - my brother has the UE BOOM and its too bassy for me.
    what should I choose? denon or charge 2?
    I want to purchase tomorrow! :)
    thanks alot for everything its a dlight hearing your recordings and compare between them - really makes a order in the mind!
    U R AWESOME KEEP IT UP!

    1. the UE Boom has no reall bass at all, maybe you confuse a boomy upper bass boost with real bass, because both Denon and JBL have considerably more and deeper reaching bass than the UE Boom, but the UE Boom is one of the loudest.
      The Denon sounds most balanced from any small portable speaker I have heard, but for many the Denon has too little bass, especially when compared against the JBL. While I would call the Denon rather analytical, the JBL sounds more fun and more punchy and it will sound more convincing at high levels, as it manages to keep more bass. Considering all aspects including batter life, charging of external devices etc, I would probably go for the JBL.

      Delete
    2. I meant to the boomy sound not that it has a real bass...
      I'm not a bass lover, I like my sound a little warm but still flat.
      For example I fell in love with the audio technica m50 but the mrspeakers mad dog I had after I broke the m50 was too flat.
      I love the sound of my Kef M200, but my Logitech UE6000 - to bassy.
      For me sound is way above battery life as I would probably charge it in my car or home or with my xiaomi 10400 power bank, for me portability is above battery and also water proof too.
      As I said I have a nice battery bank that charges at 2A so I don't need the one on the jbl.
      Also I'm afraid that if I will put the jbl in my car the bass vibrators in the side would make problem with the plastic panel where I will put the speaker, and will sound crap.
      Also I'm afraid that the jbl will be too boomy for me.
      Still you recommend to opt for the JBL?
      Many thanks!!!!!

  5. Oluv, thank you for all you do. Based largely on your reviews, I'd been planning on ordering the Envaya Mini this weekend. Now, I'm in doubt. I'd appreciate your advice, including reasons, considering that I'll mostly be listening to the following kinds of music, either on my own in a small or medium-sized room, or with family and friends outside on a deck or patio.

    Classical: Symphonic. Chamber. Piano sonatas. Voice.
    Jazz: Dave Brubeck. Miles Davis. Ella Fitzgerald. Benny Goodman. Billie Holliday. Keith Jarrett. Diana Krall. Thelonious Monk. Oscar Peterson.
    Popular: Acoustic guitar + voice (e.g., Joan Baez, Judy Collins, Bob Dylan). Eva Cassidy. Jimmy Cliff. Bob Dylan. Frank Sinatra. Nina Simone.

    1. In my experience with the Envaya Mini it is very well suited for that kind of music: it's flat response makes classical music sound pretty good for a speaker that small, and acoustic guitar with voice or jazz tunes are really enjoyable and sound very rich and smooth.

      Your mileage may vary of course, but when listening to rock or hard rock I feel like I need to emphasize the highs a bit, and put a small notch around 128 Hz when it seems to get a little "enflated" with some tracks (depends a lot on the room though), but that's my personal preference of course.

    10. Official response from Harman

      Harman has not released a firmware update for the Charge II. That update is from a third party company. We do not recommend you update the firmware from any other companies as it may cause your device to not function properly. Any updates from Harman will be available on our official website JBL.com. You can try resetting your charge to clear out any possible issues. In Power ON mode, press the Power and the Volume Minus buttons simultaneously. The Charge now turns off, and when you turn it on again, it has been reset. I do apologize for the inconvenience.

      Delete
    11. Harman is an international company with service centers all over the world. there might be crappy service like in your case, or good service like in my case, where i was directed to an official harman service center with an official technician who had official harman software to apply the firmware. if they claim something different, they have either no clue, or they have other reasons to fool their customers, i don't know.

      i am sorry for you that you seem to live in a country where customer service obviously doesn't value much.

    12. I currently live in the US and I got the response from the US team. Terrible, indeed. It seems that the European branch does a better job.

      Anyway, I will return the unit tomorrow (feeling sad). It's just a matter of principle.

    2. Thanks a lot. I jumped on the 88€ offer from Telekom and just got a Charge 2. It even has firmware version 1.4.1 :-)
      I will put my Envaya Mini up against it, just as I have done a wile ago, when the issues of the Charge 2 made me pick the Envaya after pitting those two against each other.
      I really love my Envaya and am very pleased at how full and rounded it sounds even outside with no wall behind it to reflect the bass radiator output. But the battery life difference alone is something to be considered, as well as the less directional sound of the Charge 2. Sure attaching the Envaya to a USB power bank works fine to extend its playtime. But I'd rather have the more streamlined experience of a device that doesn't need to be tethered to anything to get through a long night out (not even speaking of having to carry around the power bank and a cable).
      I'm very curious how this second shootout will end. Especially as the former downfall of the Charge 2 - performance at low levels- is now fixed.

      Delete
    3. The Charge 2 won. But I am under the impression, that its sound changed significantly between the version that just had the lower base problems. I remember it being closer to the Envaya Mini. It seems to have more "sparkle" now, making it sound more open.

      But this makes a very clear use case differenciation now (only based on sound, not further feature differences):

      Envaya Mini for classical, Jazz and generally more "slow"/restrained music at lower volumes and for few listeners, who can sit pretty much right in front of it (quite directional, very flat repruduction).
      Charge 2 for popular music, anything that is aimed to "party" or should have some more punch and this at medium to higher volumes with a full room or a scattered bunch of listeners (not too directional, more sparkle and punch).

      Maybe you could post a small piece about this pair, as this seems to be quite a recurring question in the comments of your articles and videos. No wonder, since these still are the best option in this price range.

  8. I got my Charge 2 last sunday. I went to the local MediaMarkt and I started with checking the firmare of all the demo units that are on display. They were all 1.4.0 or even 1.3.8 so I talked to one of the employees and they were not allowed to open one of the boxed units to check the firmware of that one. So after double-checking their return policy I got one and directly after paying I opened the box and powered the unit on to check the firmware and yes, it was 1.4.1.
    The unit is really great although it seems to have some trouble when playing highly dynamic tracks like from a lot of Sheffield Labs Jazz/Pop recordings. If the track is already somewhat compressed it works better.
    What I did see is that the serial numbers of the demo units were all ending with a 4 digit serial number, the boxed units all had a 5 digit number.
    A user updateable firmware would be a great addition though...

    Unfortunately we have not launched any firmware update for the unit. There is a news that a new update is available but I would request you not to update the firmware with any independent upgrade file as it may affect the working of the unit.

  26. The firmware worked great.

    Then like an idiot I tried to reflash it with the saved.dfu. Now its stuck in DFU mode. Any help at all would be highly appreciated.

    Thanks,

    1. I repeated your mistake. Updated firmware to 1.4.1. Worked perfectly. Wanted to reflash saved.dfu but changed the mind and didn't begin to reflash. Pulled out a usb and the loudspeaker remained in the DFU mode. Only power button lights, but nothing happens. Any help to exit DFU mode. Thanks in advance.

    2. Pressing bluetooth and vol(+) at the same time reset the device I think. Let me know if that worked :)

    3. Hi,

      Thank you for the advice but unfortunately it didn't work. Have tried reflashing it several times now.

      I think I need to figure out a way to access its UART interface.

      Looks like its core is a Sunitec BM153 with a CSR bc57e687c chipset.

      Maybe someone case provide us with a dump of their working module

      Thanks,

    8. For debricking after an unsuccessful flashing, have skills in soldering smd elements. Pins small-sized and possible to damage pins and finally to break JBL. Accuracy is required. The CSR USP-SPI adapter is required (for example http://www.ebay.com/itm/CSR-USB-SPI-ISP-Bluetooth-USB-SPI-Download-Module-Chip-Programmer-Debugger-/291552669118?hash=item43e1e4adbe) or use this LPT-SPI http://byron76.blogspot.com/2011/09/upgrade-your-bluetooth-module.html
      In JBL Charge 2, BC5 M chip
      Teardown JBL Charge 2: Remove side covers of passive radiators, for this accurately remove a rubber panel with buttons (enough to unhitch it on edges) latches which don't allow to turn side covers are visible. To hook a latch and to turn a cover. Teardown process in this link http://www.youtube.com/watch?v=IElTLOlAGMo.
      Solder to pins direct on board. Pins very small. Wires with thin core need. Solder to contacts of the BC5M (27 - SPI_CSB, 28 - SPI-MISO, 29 - SPI_CLK, 30 - SPI_MOSI). Connect JBL to USB that a supply on BC5M.
      For unpacking .dfu use utilities (DfuUnbuild.exe) from CSR BlueSuite. Befor flashing dump you .psr (PStool.exe) and firmware from (BlueFlash.exe).
      If you can't do this sell me your JBL.
      Who needs a firmware dump .dfu or .fs/.xdv/.xpv format or datasheets, write here then I make a link.

  29. Oluv, with your new unit with 1.4.1, do the battery lights turn off if you're charging another device with the speaker via the USB port? I upgraded mine to 1.4.1, and the battery lights do not turn off if another device is connected to the speaker via USB. It also continues charging USB devices when I turn the speaker off, and the battery lights remain on. It did not keep charging devices when turned off before 1.4.1. The only way to make the battery lights turn off is by not having any device connected and charging when I turn the speaker off. Is this how yours behaves?

    ReplyDelete

    1. yes they stay on during charging, the Xtreme does the same. I actually find this useful, as you can see that the speaker does something even in off-state. It will finally go off, if you remove the USB-wire or deattach the charged device.

      Delete
    2. With my speaker, if it is connected to power and I have another device connected via USB, the lights do not go off no matter what. If the speaker is charging and I turn it off while something else is connected, the lights stay on even if I disconnect the other device. The only way to make them turn off is to unplug the speaker's power cord or turn it on and then back off with no USB device connected.

      Delete
    3. If the speaker's power cord is not connected and I turn if off while a USB device is connected, the lights stay on, but they turn off if I disconnect the device. They only stay on if the power cord is connected, and do not go off when I unplug the USB device. Only by unplugging the speaker's power cord or turning it on then back off.

      Delete
    4. I didn't try it with the Charge 2 attached to mains as well. But why do you want to charge external devices, with the Charge 2 attached? I only use this function when on the go

      Delete
    5. Well when I'm at home I use the Charge 2 as my main speaker for my laptop, because it sounds fantastic, so I have it behind my laptop on my desk and charging, and the USB ports on my computer are being used and there's not a free space on my power strip for my iPad charger, so I just have my iPad charging via the speaker. It's not using the speaker's battery since the speaker itself is charging anyway.

      For some reason it just now worked correctly, but only once. I turned it off, waited a few seconds, then unplugged my iPad and the lights turned off. I've been trying it over and over again and can't get the lights to turn off again after unplugging my iPad with the speaker off and charging.

      Delete
    6. how long do they stay on? when the charging procedure of the Charge 2 finishes they don't go off either?
      There can definitely be some strange behaviour sometimes. The Charge 2+ unit that I had here for my test didn't finish charging procedure with all lights off, but rather all lights blinking. I am not sure what that means, but some others had this problem as well.

      Delete
    7. As far as I can tell, if something is connected while the speaker is charging and I turn the speaker off, then unplug the USB device, the battery lights just do not ever go off.

      Delete
    8. Alright, so I just now repeated the procedure when I noticed that the final battery light was flashing. It appears that if the speaker is still charging, turning it off with a device connected and then unplugging the device results in the battery lights turning off once charging completes. If the speaker is fully charged and all 5 battery lights are solid, they do not turn off after turning the speaker off and then unplugging the USB device, while the speaker itself is still connected to power. It certainly is a strange set of circumstances.

      Delete
    9. Haha, we demand custom LED light patterns, JBL!

      In all seriousness, if you have a moment and don't mind testing it, could you see if your unit does the same thing? I wanted to know because yours was upgraded at a service center by a professional and mine was done with a file off the internet. It would put my mind at ease if yours acts the same way.

    2. If you follow the steps and use the files supplied here, is there still a real risk of bricking your JBL charge 2? I mean it sounds like this is happening due to USB cables being removed at the wrong moment, or trying to reflash the unit. I can get a charge 2 for a good price but I know I will need to upgrade it to 1.4.1. I just want a good idea of any risks that are out of my control when attempting the upgrade.

  40. Thanks OLUV
    I just purchased a 1.4.1 Charge 2 of course at GBP 55 from a ebay seller
    complete in box and twith warranty a lower price than the Charge 2+ which is GBP 100 almost twice

    I decided to do so after reading your blog
    Earlier following your blog
    I was convinced about the Sony SRS X3 in terms of price, comparison with
    the bench marked Bose SoundLink Mini and the SRS X5, all of them compare very favourably in terms of sound quality
    and volume
    The Bose upgrade is way too expensive at GBP 165 although it has now USB Charging
    The SRS W5 downside is that it' s volume drops when played on battery and not on AC charge
    Both X3 and X5 are basically tuned for indoor listening

    The SRS X3 at 20Watt is chargeable by USB and appeared the best buy for me in terms of build quality, price and sound and features overall

    Volume wise and compared both SRS W3 and the JBL Charge 2 are
    both about equal altho the JBL has a lower stated 7 + 7 Watt output..the difference is not obvious
    I decided to go for the JBL Charge 2 as it has a longer battery life and sounds better outdoor

    I am writing to share the above with other followers of your blog
    I wish to thank you for your blog and the immensely valuable information you provide
    I am sure you are closely tracked by the manufacturers not to mention thousands of followers on line
    and held in very high regard

    Also last point I am not fascinated by the water pro0f claim of the Charge 2+
    This is because its higher price does not justify it

    may i have your help?

    I've bought my JBL Charge 2 (Blue) in Portugal, one year ago, unfortunately it stoped working.
    It’s a very nice speaker. I was very happy, until a few days ago...
    Even after completely charged, when i press the on/Off button it stays On only for one more second, after this few moments it turns off. Is there any solution to solve this problem?
    Thanks!

  56. I own a JBL Charge 2+ and I've found a strange issue when using it attached (wired) to my portable keyboard: after a couple of minutes, there's a clear delay (latency) from the moment I play a key and the moment sound is output. If I turn the speaker off and then on again, this delay goes away, but it's soon back after a couple of minutes. I guess it's some time drift due to DSP processing, and I imagine that one could fix that with a firmware update. Perhaps there's a way to disable all DSP processing, especially when not using the speaker via bluetooth?

    does it means that my speaker is new production after firmware 1.4.1 release, or maybe my speaker was refurbished?:(
