The Creative Soundblaster Roar costs exactly the same as the JBL Charge 2. The Roar is about twice as large and heavier and it packs quite a bit more features like playback from MicroSD, NFC, AptX etc. The Roar is definitely not a bad sounding speaker but directly compared to the JBL Charge 2 it suddenly gets a bit of a kitchen-radio character to it. Especially listen to both at maximum volume at the end of the video and you should hear the Roar struggle with severe volume pumping-effects:
I am not sure if you really want to hear the direct comparison of the JBL Charge 2 against the more expensive UE Boom, but as many seem to like the UE Boom that much and always defend it with all their energy every time I poke fun at it, here you are:
Of course the UE Boom will play louder, but the overall sound quality it puts out is not even worth losing any further words. It is just if you really need this loudness, that it might have its purpose, but then I might also take a cheaper
Pasce Minirig which plays equally loud, but with a better and more punchy sound than the UE Boom!
Now let's have a look at some frequency response measurements. First an in-room response at medium volume and 50cm distance compared to the old JBL Charge in green with 1/6th octave smoothing (to read more on my measuring setup, have a look
here):
That's quite impressive for the JBL Charge 2 and pretty smooth overall with only some stronger hump at 14kHz which usually shouldn't be heard that much or might even be responsible for the sparkle in the treble. The old Charge has some overly bloated upper bass, with hardly any bass below 100Hz and an equally bloated treble as it was the case with the JBL Flip, although not as extreme (you can see a measurement of the JBL Flip together with the Mini Jambox
here for reference).
Here in pink you can see the measurement from 30cm above, which is more or less 37� off axis. Although there is some treble loss when listened off-axis, treble is still present and makes the response even slightly flatter without that obvious hump at 14kHz.
To minimize as much room influence as possible I also tried a nearfield measurement from 10cm close to one of the drivers. As I can only estimate where the drivers are located, because you cannot see them through the grille, the measurement might not be 100% correct, but we should nevertheless get a first idea. For comparison I also did the same with the Soundlink Mini, which you can see in blue (no smoothing):
Now this is what I would call an examplary frequency response. The JBL Charge 2 is nearly completely flat within +/- 3dB from 75Hz to 9kHz (interestingly JBL even provides 75Hz as the low frequency limit in
their specs which would be pretty much spot on unlike many others who claim their speakers to play down to 20Hz while in reality they won't even play 100Hz well). Although the Bose Soundlink Mini might have a deeper reaching bass at the same time it has a very uneven response with both stronger dips and humps within the whole spectrum.
I think the JBL Charge 2 is the proof that the best sounding speakers are still those with the most natural response in contrast to all the speakers with an excessively sculpted sound...
Where the JBL Charge 2 fails completely though is at lower volumes. If you like to listen to music at lower levels, you will probably notice the higher than average noise-floor of the JBL Charge. It is pretty obvious when compared to most other speakers I have tried, the only one being the Soundblaster Roar with an even stronger noise, especially with both "Roar" mode and "Terabass" enabled.
The JBL Charge 2 has only 16 dedicated volume steps and the change in loudness during the first 5 steps is set much too high. The volume control is in sync on both the speaker and the iPhone, so there is no way to get any further steps in between, at least not on an iOS device, I am not sure if all android devices act in the same way. The Mini Jambox for example also has 16 steps only, but the volume curve starts with a much flatter slope, to finally rise at higher levels. On the JBL Charge 2 it is exactly the other way round. Each step up to 5 nearly doubles the loudness, while from the 5th step upwards the change in loudness decreases more and more. Pretty stupid approach if you ask me, and I would definitely prefer it the other way round with more and finer subdivisions at lower levels. As bad as the UE Boom sounds, at least the guys at Logitech manage to bring out some improvements with every new firmware they issue. The latest firmware for the UE Boom added 32 volume steps instead of the initial 16 which allows for a much finer volume control than before, although it was already better before than it is now on the JBL Charge 2. I also doubt that there will be ever any firmware update available for the JBL Charge 2. I have not seen any portable speaker from Harman yet which would allow for updates.
Let's have a look at the measurements of all the possible volume levels available from the JBL Charge 2:
The problems at low volumes are not only related to the strong jumps in loudness, but also seem to base on the sound processing problems I already mentioned
before.
Update: All issues were finally fixed with the latest Firmware, please check out my posting
here.
It is pretty obvious from the measurement, that the first curves are missing bass compared to the louder settings. The 3rd curve finally starts to gain a boost in bass, although I rather think this to be the measuring of some processing artefact, as I in reality I have not heard any bass increase until the 4th or 5th level which finally seem to sound correct. It is just from the 7th level upwards, that the speaker starts to dial back bass slightly, with even stronger bass reduction at further levels. But thankfully the JBL Charge 2 manages to retain more bass at maximum volume than all the other speakers. It will still sound quite full-bodied and punchy, although the stronger compression will be noticeable as well.
Low volumes are quite strange though, while most other speakers tend to boost bass at lower volumes, the JBL Charge even takes away bass at its lowest volume settings. I wouldn't complain if bass amount remained the same, but they really dial bass back at the first and second step, WTF?
I am not sure what went wrong, if the DSP programmer was drunk or smoked too much pot when he did the tuning. Because together with all the artefacts and additional distortion the speaker is producing now, I cannot really take it serious. A speaker that cannot play at low levels, or cannot play particular tracks because they cause distortion, and it shouldn't play loud for longer periods either, because the drivers might start to chirp...
The JBL Charge 2 could easily be the absolute top model in the whole range of portable Bluetooth speakers. In my opinion it easily bests the Bose Soundlink Mini in overall sound quality with a much smoother and more natural sound, but still enough punch to the bass to really make music satisfying. It sounds better than most bigger models, although it won't play as loud. JBL could have tried to tease out a bit more power of the speaker to really stand out from the crowd of competing speakers, but a Soundlink Mini can play just as loud, similarly priced but slightly bigger models like the Soundblaster Roar will play louder with a more punchy sound at the same time.
It is the sound processing issues that really put me off. I tried 2 different units with different colors from different suppliers and both behaved exactly the same. Many might even not notice that as they will be happy about the JBL Charge to produce that much punch, but anyone serious about music will hear that something is not alright with the speaker. Every second track I played through the Charge 2 distorted, when listening to acoustic Jazz at lower volumes I could hear side noises and growling sounds simply not present in the original recording. I am yet to hear from JBL about these issues, as I have sent an inquiry to their support, but so far no reaction at all. Meanwhile I was in contact with Harman support, which was not very informative though. They indirectly confirmed the issues and suggested to return the speaker but didn't offer any prospect of a fix. When I asked if there will be any updates, they just answered that if there were updates they would be available directly from their site.
As it is now I cannot recommend the JBL Charge 2 without restrictions. It is definitely a great sounding speaker, one of the best if not even the best I have tried so far, but it has sound issues which cannot be denied. Apart from that I would have preferred it a tad louder. The JBL Charge 2 is about comparable in loudness to other speakers like the Bose Soundlink Mini, Sony SRS-X3, Klipsch GiG etc. while speakers like the old JBL Charge or the UE Boom manage to play considerably louder albeit with a much more clunky sound. I also see the exposed passive radiators very critical. This is the worst you can do for a portable device and I wonder how Harman is going to deal with this in the upcoming and twice as expensive Infinity One, which has the passive radiators also completely free. They could have added a protective cover as it was the case with the old JBL Charge, but currently you can only try stuffing it inside a sock in order to not getting it damaged during transport.
The JBL Charge 2 could even substitute a small home stereo system, if 2 speakers were able to pair for wireless stereo. When I directly compared the JBL Charge 2 with a Sonos Play:1, I preferred the JBL to tell the truth, but one single speaker will never give you any stereo separation although the sound is serious enough to satisfy even more demanding needs.
If JBL address most of the issues, like the rough volume control and the processing artefacts and if they also mange to improve Bluetooth connectivity, so that the speaker will always automatically reconnect to any known device, I could definitely live with a speaker inside a sock!
