Too bad I of the supposedly "Helpful Customer Reviews" had me fooled and other critical voices like Raphael M (08/25/2014) and Gerhard (26.02.2014) have not taken sufficiently seriously: The boxes have indeed a good sound, a good appearance and are - just for Bluetooth - easy to install and operate in my field of application without BT Disorder. In that regard, so a strong buy recommendation. But if the boxes (ie connected to the mains without switched source) already in standby mode give a faint buzzing noise, will not be a topic for the sound of a garden party, for use in the living area, however very. Especially as the hum is so loud that it is heard in classical music even with Piano points. , This buzzing sound occurs unfortunately independent of other possible sources of interference (domestic WLAN, BT-operation, other musical equipment to the mains power supply) that is so device-specific. For me a killer criterion, all dismantled and returned consuming. Too bad!
