Hearing Aids

Invisible-in-Canal (IIC)

The most discreet hearing aid — truly invisible to others.

Invisible-in-Canal hearing aids are the smallest hearing aids available, sitting deep in the second bend of the ear canal where they're completely hidden from view. They're the ultimate choice for users who want absolutely no one to know they wear hearing aids.

Despite their tiny size, IIC devices deliver clear, natural sound by leveraging the ear canal's acoustics. They're custom-manufactured from a deep impression of your ear canal for a precise, comfortable fit.

Common questions

Invisible-in-Canal FAQ

Answers to common questions about Invisible-in-Canal (IIC) hearing aids.

Not everyone's ear canal is suitable for IIC devices. We'll assess your ear canal anatomy during your appointment to determine if this style is an option for you.

IIC hearing aids have a thin, clear removal cord that you gently pull to slide the device out of your ear canal. It's simple once you've practiced a few times.

Because they're custom-made from a deep impression of your ear canal, IIC hearing aids are designed for a precise, comfortable fit. Most users forget they're wearing them.

Most IIC hearing aids do not currently offer Bluetooth due to their extremely small size. If phone streaming is important to you, we may recommend a RIC or ITE style instead.
