The listing, Hearing Aid, Re-Chargeable has ended.
Re-Chargeable Hearing aid. Unit rest behind ear, earpiece goes inside ear.
I bought this a few months back, and didn't think about it with my glasses. It won't stay on if you wear glasses at the same time. I only needed it for when I wore my glasses. My loss, your gain.
It has different size ear pieces as well (I actually never inserted the one it has on the unit, since I couldn't even get it to stay on with my glasses on).
No booklet or info, I can't find where I may have put it.
The hearing volume is adjustable.
These devices are inexpensive (I think I paid 30 or 40 bucks for it), so not to be confused with Rx Hearing Aids that cost hundreds or thousands. They supposedly just assist persons with slight hearing difficulty. I did buy the one that goes inside the ear, and it does help my hearing issues tremendously.
