In my case, the device was placed in the living room at a distance of about 3.5 meters to the sofa.
At low volume, the operating noise is always heard, for example if there is a short break between two songs or in a Talk Round nobody speaks.
Listening to soft music can be completely forgotten, as the operating noise is mixed in this case with the music. When listening to loud music, the sound of the system is good.
The other, very extensive functions of the system I have not tested, because the frustration is too large. The plant was returned immediately to Amazon.
In my view, the system is not for sale. From any of the documentation accompanying the system can be seen even on the documents available on the Sony website on the internet to this system that the operation of the system is connected to a running noise.
