To add something of value to this, yes I wear a hearing aid, courtesy of Uncle Sam and a very near and loud explosion 25 years ago. I'm over half deaf in one ear so the VA supplied me with a Phonak Audéo S YES BTE unit. It literally took about a day to get used to it and nobody even knows i'm wearing it. It came with a device to raise or lower the volume when neccessary. The battery is the same size as used in watches. Phonak also makes waterproof devices btw but i didn't see the need as I take it out when on the boat anyway as the wind gets real loud! It's formed to your ear canal and is quite easy to put in an take out. The difference in hearing is totally amazing.
