The most common hearing aid styles and features are described below. Keep in mind that some styles and features cost more than others, and health insurance coverage for hearing aids varies. If you find the best hearing aids for you, though, the benefits may outweigh the cost.

Optional features
Extra features can tailor hearing aids to your needs. A few common ones are listed below.
-
Telecoils let you switch from the hearing aid’s microphone to a special setting that works better with phones and in certain auditoriums, theaters, and museums that have telecoil-compatible sound systems.
-
Direct audio input feeds sound from a sound system, computer, radio, or microphone directly into your hearing aids.
-
Directional microphones pick up head-on sounds and reduce background noise.
-
Customized listening programs store programs to adapt to changes in noise level. For example, you can have one program for your home and another for crowds.
Noncustom type hearing aids
The hearing aids shown here are customized based on the shape of your ear and the type of hearing loss you have. Noncustom (ready-to-wear) hearing aids may also be a choice. These are often purchased through mail order or over the counter. Noncustom hearing aids may cost less than custom hearing aids. But they may not work as well because they have not been programmed for your specific hearing needs. And since they’re not made to fit the shape of your ear, noncustom hearing aids may not be as comfortable. Your hearing health care provider can help you decide which type is best for you.
