I use Bluetooth with my phone and sometimes my laptop. My current hearing aids can stream directly from devices with Bluetooth LE audio; no relay dongle necessary.

But at home I often use telecoil. It's one of the killer features for hearing aids that no one seems to know about. Short-range (inches to a few feet) baseband analog radio.

I have a transmitter set up in the living room. If I come within a few feet of the couch I'll hear the television. Got another at my desktop computer in the office. I also have a loop I put around my neck when I play my electric guitar. Telecoil transmitters will plug into any standard line audio source.
