I use a ReSound Multi Mic (see https://www.resound.com/en-us/hearing-aids/accessories/multi-mic https://www.resound.com/en-us/hearing-aids/accessories/multi...) with my MBP. It plugs into the headphone port and transmits the sound to my ReSound hearing aids. As you can see at the referenced URL, the Multi Mic has other capabilities as well. I’ve used it to hear speakers at conferences, college classes, and other talks given by speakers who were at a distance from me. And, I’ve used it to pick up the signal sent by venues’ audio loops at other speaking events. The only feature it has that I haven’t used is its “conference table mic” - ReSound says I should be able to lay it flat on a table I’m sitting at with others and it’ll automatically zero in on one speaker or another when they talk and send that person’s voice to my hearing aids. I gotta’ test that feature out one of these days soon because that sounds amazing.
