After power-as usual-the receiver simply select from the Bluetooth list. He there the entry TT-BR02. After pairing, you can start immediately. A noise I could not hear, the signal is very clear transfer. I have the more expensive receiver Bose BT10 borrowed even a week from a friend and can sound no differences on this matter (although I also earthly demands on the quality had with my Internet streams and normal MP3s). Anyway, I'm very happy with it.
Is ideal and particularly emphasized that this adapter can be powered by 5V USB. So you can connect it to the PC or USB hub adapter easily. Personally, I'd never buy a Bluetooth receiver that comes with power supply and thus occupies space and outlet permanently draws current from the power supply. And the PC there anywhere USB sockets. The newer AV receivers such as the Yamaha RX-V475 and others, have also been a 5V USB output, so you can put such an adapter just behind the AV receiver, as long as this does not have Bluetooth.
Also in the car use is possible. Who built the 350 mAh is not enough, the power supply can also make sure USB adapter.
Criticisms? Well, a design prize (of course a matter of taste What is) wins the box does not, but it does very well what they want and at a reasonable price. 4.5 star arise rounded 5. Thank you for reading!
