Behind-the-Ear (BTE)
This style fits behind your ear and comes in a variety of sizes. It is attached to an earpiece, or earmold, that is  custom-made for your ear. BTE instruments fit a wide range of hearing losses - from mild to profound.

In-the-Ear (ITE)
This style is also custom made and fills your entire outer ear. A full shell ITE provides access to telecoil and multiple listening programs. It is typically for hearing losses ranging from mild to moderately-severe.

In-the-Canal (ITC)
This hearing instrument is custom made to fit your ear. It is slightly larger than the CIC. This style provides access to multiple listening programs and is appropriate for mild to moderate hearing losses.

Completely-In-The-Canal (CIC)
This is currently the smallest custom made hearing instrument. The shell is designed to fit deep inside your ear canal and be practically invisible. Often, these devices are limited in the number of programs and options. They are most appropriate for mild to moderate hearing losses.
