Completely-in-the-canal hearing aids are molded to fit inside your ear canal and can improve mild to moderate hearing loss in adults.
A completely-in-the-canal hearing aid:
Is useful only in mild to moderate hearing loss
Is the least noticeable in the ear (practically invisible)
Is less likely to pick up wind noise because the ear protects the instrument
Easy to use for telephonic conversations
Uses smaller batteries, which typically don't last as long as larger batteries
Doesn't contain extra features, such as volume control or directional microphones
Age criteria- not advisable for young children
