In the small cardboard box is the transmitter, a short jack-jack cable, a jack-RCA adapter, a micro USB cable and a detailed and illustrated instructions German. In the manual, everything is well explained and even for me, the connection worked right away.
The transmitter here has the great advantage that it can also be used during charging, which can not all transmitters after my research. The small battery should last up to 10 hours, I have not tried it yet, because the transmitter is always hanging with me always on USB connector on the TV.
Need to connect the Bluetooth device you simply turn on the transmitter and the headphones and put into pairing mode. After that, it takes only a few seconds and already the devices are connected and the sound is transmitted.
The transmission quality in my opinion is very good and in 3 feet away also completely trouble-free. Even when walking around there is no interference, which indicates a strong transmission power.
I would this transmitter at any time to buy again, by me there 5 Stars!
