On a Mac mini, Bluetooth 2.1, sound is infamous (low quality, crunches) Fortunately we have the cable (poor) to use wired. By cons, on a Nexus 7 Bluetooth 3.0, the sound is very good. At first, the impression was not convincing (lack of bass), but eventually we made it :)
Small inconvenience: in the dark, there is always a blue light flashing. The battery life is very good, but when the battery is low, beeps undertake to perform charging.
