The sound was really good, rich bass, clear highs - but ultimately there were regular problems with Bluetooth.
Although my cell phone was removed as the sender only about one meter from the speaker, there was every play-outs. Especially if, for example, a call for a colleague was looped on my telephone.
The bugged so that I returned the speaker again.
Now I have the Bose SoundLink mini and there are no problems at all.
Who buys cheap, buys halt but twice!
