OTE - over the ear

"Open-fit" or "Over-the-Ear" OTE hearing aids are

small behind-the-ear type devices. This type is

characterized by a small plastic case behind the ear,

and a very fine clear tube running into the ear canal.

 Inside the ear canal, a small soft silicone dome or a molded, highly vented acrylic tip holds the tube in place. This design is intended to reduce the occlusion effect. Conversely, because of the increased possibility of feedback, they are limited to moderately severe high frequency losses.
