With this small box you can not really go wrong.
The sound is great. either via the supplied AUX cable or via Bluetooth, it makes a really great sound can be really loud and the bass is for such a small part really awesome!
I can not say much because I so now no hours at a time listening to music, but according to many recessions and reports it is definitely sufficiently over the term personally.
Anyone looking for a portable sound system with ratio-moderately severe sound and Bluetooth / -Freisprechfunktion, will be sure happy with the small cylinders here.
