Rics are a type of open fit hearing aid that use a thin plastic micro tube that extends from the body of the hearing aid housed behind the ear over the outer ear and into the ear canal.

The earpiece of an open fit hearing aid is a small soft rubber or silicone cap which is much more comfortable than the tightly fitting earpieces of btes cics etc.

This makes the style a good choice for people with mild to moderate hearing loss.

An open fit hearing aid is a variation of the behind the ear hearing aid with a thin tube.
The amplifier increases the power of the signals and then sends them to the ear through a speaker.

In the case of an open fit hearing aid the amplified sound travels through a small tube or small wire to a tiny dome or receiver in the ear.
The case of an open fit hearing aid sits discreetly behind the ear with small tubing connecting it to the ear canal.
