Hearing impaired TV headsets aren't Bluetooth, they're proprietary protocols. Some are pretty good - but cost upward of $300. Some are reasonably priced - but only work for about the size of one room. A true class 3 BT setup will cover most, if not all, of a house and not be too expensive. There just aren't any that I've found for TV use. (As far as the ones sold for the hard of hearing, I wear 2 hearing aids and I'm in my audiologists' office regularly, so I know what's available in that industry - and the ones sold on Amazon for $70 are sold by audiologists for $270, so that's not a place to look. The markup in those offices would make an old-time oil baron blush.)
