I have been for some time looking for an adapter with the wireless music I can transfer from my iPhone or my Android tablet on my stereo. I have a couple of devices tested and am what the sound quality and the service terms absolutely satisfied with the MyMusic adapter. Especially practical is the power supply via USB. I've just connected to my amplifier and thus the adapter automatically switches on with my stereo and not consume unnecessary power when not in use. I can absolutely recommend the device.
