A:Answer I use it with Sony headphones and I had to shut down all my other Bluetooth transmitting connections (like my iPhone) that are in range to get it to connect. I think the problem is the headphones, not the transmitter. They gravitate to strongest pairing source (which in my case is the iPhone). If I shut down Bluetooth on the iPhone, the headphones pair with the transmitter. So don't clean up your list, just turn off the other sources.
