I have the TaoTronics® TT-BR01 cordless Bluetooth Stereo Receiver for headphones along with the TaoTronics® TT-BA01 Bluetooth Stereo Transmitter - bought audio dongle stereo. Both devices work properly, only the description for the coupling of the two devices is not very revealing, and I had to fumble around for over an hour (wanted the two devices already send back) before everything worked. Here are my instructions: 1. At the receiver about 6 sec. Press (up red blue alternately flashes) 2. Press the transmitter approx. 1 second key (to blue flashing slowly) 3. A little wait if the recipient also flashes slowly blue are the two devices connected.
