enclosed my review of the device. A video I invite still high and (use search) which long as always on my channel "DerTestMichel".
The device is nice and small and very well made. Let there be some cable supplied with which one has div. Connectivity.
Man can receive with the device of Bluetooth enabled devices Music. So if you have a sound box has (eg MusicMan) then you can send it via smartphone the music on the box.
Or listen to the music through the car radio via mobile phone (via the Aux input).
Interestingly, however, it is if you look at the BT transmitter still buys (30 euros). Then you have a lot of possibilities.
One can of his TV through headphones watching the movies. In the car from his MP3 player via the radio listening to the music, connect to an MP3 player 2 headphones so that the 2nd headphones via BT works and would collect the same music. The range is also good. If no obstacle is in the way (thick walls, doors) then it is a good 15 meters.
On the whole, a very good device that I would buy again. The BT transmitter is called "* New version * TaoTronics® TT-BA02 Bluetooth Stereo Transmitter".
