Logitech UE Mobile Boombox review: temple of boom?
 

For its small size the Mobile Boombox sounds very good, even with the volume maxed out the sound doesn't distort. The volume doesn't go very high, however, and the sound is very directional. Like most Bluetooth speakers, the Boombox sounds better when you hook it up with the 3.5 mm jack instead of Bluetooth.
