The device was conceivable connected simply using the supplied RCA cables to the system and then hung on the wall socket. Mobile phone has found the Bluetooth signal immediately and with the sync button on the adapter both devices could synchronize within seconds.
My fear was actually most likely that you each time use again has to jump to the adapter in order to actuate the Sync button (as is the case in some of Bluetooth boxes of my friends - super annoying). But that was not the case. Activate Bluetooth on the mobile phone and the Logitech adapter has within max. 2 seconds, the connection is established. Super convenient and a gadget that I never want to miss more!
