It's very simple: you just have to plug it into an auxiliary input for the stereo and connect to the source: in my case an iPhone and this is also super simple: just go Bluetooth settings in which it appears and click to connect. The sound quality is very good: I see no difference from the broadcast WiFi via AirPlay, which requires Terminal Apple AirPort much more expensive than Logitech and asked me constantly clippings related problems sometimes insufficient flow my internet connection (especially if multiple PCs and televisions operate at the same time) and also to interference, for example when using the microwave oven in the kitchen! There, no cuts. It is for me a great product with a very good price / quality ratio.
