Hi I bought the Bluetooth adapter, so that I can leave all the hardware (I-Pad Air, Smarthphone and I-Phone) running wirelessly over my old sound system. It's just great!
Children Easy for installation and with its 15 meters reception even far enough to still control the music from the terrace in the house can.
So you stay with such a small and inexpensive yet super modern aids in your own 4 walls. :-)
