Pairing is easy. The client has to take his hearing aids out and flip something up and back down. I think it's the battery door.

The resound stuff works really well. The problem I've never solved is what do I connect it to on the AVR so you get full sound and no delay. I thought about some 2, but that's going to have a timing issue. Left and right on Main zone won't give you voices. I ended up connecting it to the analog outputs on the sat receiver
