Thanks for the advice, Jack, but he has complete hearing loss in one ear which means he has to have a special hearing aid in that ear that captures the sound from the other ear. I don’t think Bluetooth ones will do that.
I had a similar experience with my father — paid for testing and hearing aids —$800 in the early 90’s — and he rarely wore them and tinkered with them as if they were Legos until he destroyed them.
My mother-in-law had hearing aids but she only wore them going to the doctors and restaurants. I’m afraid my husband will do the same when it’s at home that he needs them and I need him to have them. The communication snafus we have are annoying at best and dangerous at worse.
