Different types of hearing aids...

The smallest, least visible model is the Completely-in-the-Canal. It fits deep inside your ear, where it's hidden in the shadow of your ear canal.

The In-the-Canal hearing aid is small enough to fit almost entirely in your ear canal, occupying about one quarter of the ear to reduce its visibility significantly.

The In-the-Ear model is a one-piece aid custom designed to fit inconspicuously within the outer portion of your ear. It is the most widely recommended hearing aid style.

The Behind-the-Ear model fits snugly behind your ear, and is attached to a custom earpiece molded to the shape of your outer ear. It is designed for a wide range of hearing loss.
