This is my first Bluetooth-box at all and at first I was shocked at the size of this small thing. After I unpacked it and loaded I thought: Ok, for that kind of money now needs to happen but what, and then it happened! Switched on, connected via Bluetooth with my Sony Xperia, set equalizer and full blast. That was remarkable what this little box out put, after all, one can not talk without shouting when the part is in the living room. The sound is excellent, the battery life for 10 hours really enough and it can be connected to any USB mini plug (PC, car or AC adapter provided) charge. Can only recommend the device, even on the terrace in a beach chair sitting properly makes the Boombox Boom ...
