Reasonable sound, decent battery life

The sound, of course, does not correspond to a "high-end" hi-fi system, but is much better than the orignal sound from the phone. From my perspective, the box is therefore sufficient to always and very straightforward with his cell phone music in "suitcase radio" to produce quality.
The connection via Bluetooth works without any problems. One star deduction, because the work volume up / down function and the skipping of songs about the same buttons, and thereby make the volume up / down very easily unintentionally to next / previous song is bound.
