Passing sound
Equaliser in the app
signal input jack
classic power cable (not via USB)
battery capacity
really fills a smaller room with sound, otherwise you'll need two
I was expecting even more power
The controls aren't visible in the dark, but I guess that's the case with all BT speakers.

the size comparison with the Extreme 3. The sonic difference is huge.
Perfect sound
performance even at lower volumes
Size and weight. That's more of a "portable" speaker than a portable..: -)

We expected a different quality of speaker for the price, the music itself sounds nice. Worse is when you want to play a song that has bass. For a 180w power output it's a big disappointment
Battery super
Bassy

Even so, this awesome speaker has its advantages and disadvantages but it is definitely worth the price! Only the price could be better to perfection!
Awesome sound without missing a detail
Total and high volume (up to 70% then the quality drops quickly )
You can take it almost anywhere with you
IP68
For a better price, take all ten!
Total tracks 9900
Terribly long charging time over 6h
For long carrying around heavy
Bass is too exaggerated
Lasts about 5 hours when you're going full blast
I'd probably just take the WiFi version a step further

Unsurpassed sound, perfectly balanced
Beautiful design
We get along wonderfully, he can call me "Mommy" baby: -)
Slightly unstable "base", but it doesn't detract from its beauty at all

I used to own the Xtreme 3 and I figured why settle for this little speaker when I can buy this monstrous and most importantly powerful JBL boombox 3, which for me is really a blast. JBL sounds the whole apartment and fills it with brutal dynamics, as if you had a home cinema. It's not necessary to have a subwoofer. Going from one room to another, down a long corridor, it feels like I'm in a club somewhere playing a few kilowatts and then in the room itself this portable little thing plays an incredibly pleasing sound filled with breathtaking Sound balanced with nicely distorted highs and audible mids. The 3 band design is noticeable and enough. The speaker carries well but unfortunately the manufacturer has not solved the base(quite flimsy). I think it's a shame. The overall impression of the product is very above average and I have to say that it is probably the best and most powerful portable bluetooth speaker I have had the opportunity to own and test. I highly recommend it to anyone who likes a good sound system for both home and away. Personally, I can't imagine having these two speakers paired into a stereo.
quality to price ratio, unbeatable
the sound is amazing and full of incredible dynamics
battery life is really great (depends on the volume)
great design (design avards)
Bluetooth 5.3
the performance is stunning
bass, mids, highs
maybe it just doesn't have usb-c
wobbly base (not well solved by the manufacturer)
