CIC or completely in the canal hearing aids are molded to fit entirely in the ear canal. This type of hearing aid is suitable for adults with mild and moderate hearing loss. The advantage of CIC hearing aids is they are less likely to pick up wind noise.

ITC or in the canal hearing aids are also custom molded, but they only fit partly in the ear canal. They are less visible but larger than CIC, and they also improve mild to moderate hearing loss. They include more features than the CIC.

ITE or in-the-ear hearing aids come in two styles: either filling most of the bow-shaped area of the outer ear or only the lower part of it. Both are suitable for people with mild to severe hearing loss. They include more features than the smaller style hearing aids such as volume control and larger batteries for longer battery life.

BTE or behind the ear hearing aids are probably what comes to mind when you think of hearing aids. This is the most conventional type that hooks over the tip of the ear to rest behind it. It has a tube that connects the aid to a custom earpiece in the earmold. It is suitable for any hearing loss, has a variety of features, and is capable of more amplification than other hearing aids.

RIC, receiver in canal, or RITE, receiver in the ear hearing aids, are similar to BTE hearing aids but have tiny wires connecting the receiver to the hearing aid instead of tubing, making it less visible.
