Another inexpensive, less than $15 new on eBay, device that works quite well when plugged into the 3.5mm audio jack on my TV or computer. It pairs with my left hearing aid with A2DP enabled. It isn’t perfect but neither is my hearing or my hearing aids. I can understand people speaking on the TV about 80% (after using it more I will up that to 90%) of the time depending on the channel sound quality. Without it I rely on captions.
It comes with an RCA plug to 3.5mm adapter jack for TVs without a 3.5mm audio output jack.
One of my grandsons told me tonight that he has one he uses in his car to connect to his headphones. We didn’t discuss the safety aspects of driving with headphones.
