I have hearing aids, connected by blue tooth to the tv sound adapter so I can crank the volume up without the wife having to hear at the same volume. I have an app on my phone that controls all the functions of the hearing aids, and one of the programs is "find my hearing aids" and not too long after I got the hearing aids and right after covid hit, I had to run to the store for groceries, wearing a mask and coming out of the store I took the mask off and didn't feel the one hearing aid slip off with the mask string. I got all the way home, about a mile, and after putting groceries away and sitting down to watch tv I realized I was missing the one hearing aid. I turned on my find my hearing aid program on my phone and it showed me on the map where the hearing aid was. I drove back to the store and found the hearing aid laying next to one of the cement pillars not far from the store entrance. if a small hearing aid can be located a mile away, why not an air tag?
