The sound is in my opinion very good. About my Bose system I hear neither distortion nor tinny sound, so top.
Note:
1) There is no reasonable guidance available, but does not interfere. You have to know that one is connecting via Bluetooth Adapter Laptop / Tablet / Smartphone only. As a rule, to see "Bluetooth Add Device" or similar.
2.) is minimal offset the Sound. When listening to music is not that important, but you look at movies, which can be disruptive for one or the other. This is no product fault, but my knowledge due to simply by the fact that the sound is buffered for the Bluetooth connection.
Addition:
The coupling with other devices work again. If only one device is connected (in my case Acer Laptop), the connection is established immediately after each restart and Hibernate.
However, if more like a device is connected, the connection is not always automatic, because the devices compete with each other.
