Receiver-in-canal (RIC) hearing aids sit behind the ear with a thin wire connecting to a receiver and soft dome which sits discreetly in the ear canal. RICs are the most popular style of hearing aid due to their comfort and discreet appearance.
Behind-the-ear (BTE) hearing aids sit behind the ear and deliver sound into the ear via a tube. The tube can either be channelled through a custom made earmould or a soft dome, which fits inside the ear canal.
In-the-ear (ITE) hearing aids are custom made to fit the shape of the ear and are the largest of all custom hearing aids. They are designed to fit the majority of the external ear cavity and can include a volume control and button to alter listening settings.
In-the-canal (ITC) hearing aids are slightly smaller than ITE hearing aids and are designed to fit the lower third of the external ear cavity. They can also include a volume control and button to alter listening settings.
Completely-in-canal (CIC) hearing aids are smaller again and are designed to sit inside the ear canal making them very discreet. The CIC is popular amongst people with mild to moderate hearing loss.
Invisible-in-canal (IIC) hearing aids are the smallest custom hearing aids available and are designed to fit deep inside the ear canal making them the most discreet custom hearing option.
