I tested this mini wall chain in specialized stores. What interested me the sound (so so, even with 2x20 watts, that sounds yoghurt pot) but the worst is that it was not possible to pair this model with a laptop or with a iphone or with several brands of recent smartphones! For me it was what made this attractive wall chain. Just to make sure I tested all channels of the brand in wall version (Panasonic SC-HC39EG in white, black and metallic), none has accepted the apparaige whatsoever, except with a Samsung phone NFC. I'm surprised there have no comment about it, but maybe I'm the only one who tested the bluetooth on these channels ... I was going to order on Amazon, although took me to test it before shop. So I dropped the Panasonic range.
