I purchased Rexton BLU RCU Remote Control when I got new hearing aids 2 years ago. It included bluetooth transmitter to transmit TV or other stereo to Rexton receiver. I simply choose a listening choice to receive it. (Programmed only by audoligist's computer).
I was thrilled to find choosing same choice let me hear PB stereo thru bluetooth. I just entered RCU password (ID) during connection setup process.
