Having grown up with radio-cassette players, Walkmen, and portable CD players in various kinds of plastic, I'm now greatly enjoying the best portable audio I've ever heard, courtesy of a Fiio DAP, a decent 3rd party EQ app, and the fab Xtreme 3. I get really very nice sound indeed when using my Chord headphone amp via line in. I have a quibble regarding JBL software though because it is incompatible with both the above-mentioned DAP and my Android phone. I understand I am not alone in this and it bothers me (and should bother JBL) because I wanted to buy two Xtreme 3s and use each as a single stereo channel but cannot because I need a working JBL app to achieve this. One speaker system is still very good though and will have to suffice perhaps until I get a DAP or phone upgrade that will co-operate with a JBL app. So, in short...Xtreme3 very impressive, software rather disappointing. I'd still gladly recommemd it to anyone who is fussy about audio quality, but why not audition first if you're unsure?

This is a good speaker, I may like my charge 5 sound better but it definitely tries to bring more bass.

Had for around 2 years isn't that loud but the size kind of excused it and battery only last a few hours in reality unless you have music whispering. Fairly sturdy build handles ya bumps and knocks without to much of a problem however as of now it won't hold charge and has to be on life support (plugged in) to work. All round decent speaker but yea if it doesn't work can't get much higher stars.
