I ordered 2 pieces to transfer sound from TV and stereo to a bluetooth headset so you can listen without disturbing your partner. One didn't work and had to be returned. Other features but it's not good for my purpose. Bluetooth can transmit, but there is no interface for connecting a headset. I found that I could "force" a connection to one of my headsets by holding it close to the transmitter. My advice is to walk past them.
