There are primarily two types of hearing aids: behind-the-ear (BTE) and in-the-ear (ITE) hearing aids.

Behind-the-ear (BTE) hearing aids have a plastic casing that sits behind the ear and is connected to a custom-made earpiece that fits inside the ear canal.

In-the-ear (ITE) hearing aids are smaller in size and are placed directly inside the ear canal, making them less noticeable.
