Behind The Ear (BTE) hearing instruments are the largest models. They can house a variety of circuit options and amplify sounds to a greater degree than most custom models. BTEs work by sending sound to the ear canal via the ear mold and clear plastic tubing, which has been molded to fit comfortably in the outer ear area.

• Easiest to adjust and maintain

• Appropriate for most types of hearing loss

• Secure fit with minimal passageway obstruction

In The Ear (ITE) instruments house a variety of circuit options in a custom-made shell that fits in the outer portion of the ear. Their size and easy-to-use controls may be helpful for people with limited dexterity.
 

• Easy to insert and adjust

• Appropriate for mild to severe hearing loss

• Custom-made shell fits snugly in ear

In The Canal (ITC) instruments are custom designed to fit in the ear canal. ITCs are discreet, yet still slightly visible within the outer ear. ITC instruments offer a variety of circuit choices that would have previously required a larger aid.
 

• Less visible than BTE or ITE

• Appropriate for mild to mildly severe hearing loss

• Variety of circuit choices despite small size

On The Ear (OTE) instruments feature a comfortable, “open” earbud which conforms for an instant, secure fit. OTE hearing aids are appropriate for mild to moderate high frequency hearing loss.
 

• Comfortable "open" earbud promotes airflow and conforms for secure fit

• Appropriate for mild to moderate hearing loss

• Micro-thin tubing and small attractive case

Completely In The Canal (CIC) instruments are the smallest and most discreet aids available. CICs are custom designed to fit entirely in the ear canal, improving sound quality and reducing feedback. CICs are popular for their aesthetic appeal, but the physiology of some people’s ears may make the style unsuitable for them.
