I was looking for a mobile speaker for laptop, smartphone or tablet. After a long search, I came across this. Bluetooth connection problems, the loud beeping could have been omitted. But the sound is absolutely incredible - for a device of this size and nature of this, the battery life.. Absolutely great. However, the data rate of the source also appears to play a role. Some Internet radio stations sound falls just slightly. But that is not on the device. The sound is very clear, transparent, 'translucent' and good. Of course, no super-bass, but very balanced. In this respect: strong buy recommendation!
