Have been unpacked and connected to the included power supply the device. Immediately after turning on and plugging in the iPhone has been advised of the download the corresponding Sony app. After download and installation I have started directly Spotify on your phone and you could be heard in good but not exceptional quality music. Also with iTunes music played sounds good but not super great at.
Also via Bluetooth can be easily coupled with the iPhone Dock, where the unit only remembers the last Bluetooth connection, means you have to re-connect any device that you just want to use for playing music. As I leave plug the iPhone anyway to load on the device, I use the dock via Bluetooth as a speaker for my notebook.
My conclusion: The operation is not simple. The sound is ok but does not remain in memory. The design fits well into the living room and shines with its simple elegance. Am satisfied.
