Invisible-in-canal (IIC) hearing aids are the smallest custom hearing aids that are available. This kind of hearing aid is designed and sculpted to fit entirely insides your ear canal. This makes them almost invisible to those around you.
Benefits:
One of the big advantages is the small size and almost invisible appearance of the hearing aid. This makes them a very discreet option if you would rather not advertise the fact that you’re wearing a hearing aid.
The location of the microphone in the ear canal, as opposed to behind the ear, can help with using the telephone and the preservation of the natural acoustics provided by the external ear. This helps with the localization of the direction of sound from in front of and behind you.
