A completely-in-the-canal hearing aid is molded to fit inside your ear canal. It improves mild to moderate hearing loss in adults.
A completely-in-the-canal hearing aid:
- Is the smallest and least visible type
- Is less likely to pick up wind noise
- Uses very small batteries, which have shorter life and can be difficult to handle
- Often doesn't include extra features, such as volume control or a directional microphone
- Is susceptible to earwax clogging the speaker
IIC and CIC styles are the smallest and most discreet hearing aids available. "Invisible in the canal" IIC styles are as described—virtually invisible. A wearer places them very deeply in the ears, and they must be removed by tugging on a small pull-out string. "Completely in the canal" CIC are very similar, but don't sit quite so deeply within the ears.
These styles are typically fit for people with mild to moderate hearing loss. Because of their small size, they don’t usually come with any manual controls, like volume wheels or program buttons.
