There is a wide range in the price of hearing aids. Medicare does not cover hearing aids. You are encouraged to request your employer's health plan to cover hearing aids. Hearing aids are small, so it is helpful if you can manipulate small objects. If you can pick up a dime off of a table, you will probably not have a lot of difficulty handling a standard hearing aid.
Some hearing aids have larger volume control wheels to make handling easier.
Some aids are equipped with a remote control that you hold in your hand to turn the aid on and off, and to adjust the volume. Since you can see the buttons on a remote, and they are relatively large, it makes it easier to manipulate the aids. There are some hearing aids that use rechargeable batteries, so the user does not have to worry about changing small batteries. You don't need to be an electronics expert to use hearing aids. As with most new things, there are things to learn and a period of adjustment.
