The completely-in-the-canal hearing aid is the smallest aid possible, designed to sit inside the canal.

Advantages

This is a cosmetically appealing hearing aid as it is almost invisible to the eye.  This type of aid is  excellent for telephone use as there are no switches and the phone sits against the external ear quite well.  There are several acoustic advantages with this aid as the hearing aid uses the ear for enhanced directionality.

Disadvantages

Certain hearing losses and certain ear canal shapes exclude the use of this type of hearing aid.  Battery life is very short because the aid uses very small batteries.  Some clients find the placement of this very small hearing aid difficult.  It is an expensive aid.  The hearing aid is so small that it has no controls requiring an automatic circuit, which adds to the cost.
