I've been wondering whether one of the newer designs of tiny Bluetooth transmitter/receivers would be good for pairing an analog TV set to a Bluetooth hearing aid receiver a long-distance friend is using. I don't have much experience with Bluetooth, except for having just gotten a pair of these dual purpose units recently to connect my analog headphones and line out of my RME breakout box, while doing mic checks for recordings.

My friend tells me that the systems the hearing aid company sells are quite expensive and I'm not too sure that they're even designed to work with analog TV, or amplifier. Does anybody have any opinions about whether my idea could work to give this person a way to listen to their TV wirelessly and still know when they're getting a phone call on their smart phone, among other things?

I'm not sure where else to look for information that would help me with my specific scenario either, so any ideas there would be great.
