ITE hearing aids are designed to fit into the outer ear and in fact over the entire ear opening. In-the-Ear hearing aids can handle most types of hearing loss. ITE hearing aids are not a good choice for children in that their ear openings are always growing, making the fit looser over time.
Another disadvantage to ITE hearing aids is that the tiny volume controls and battery doors are hard to manipulate. Two advantages are that they are fairly cheap and not as noticeable as behind-the-ear (BTE) hearing aids.
ITE hearing aids come in 3 styles: full-shell (FS), half-shell (HS) and low-profile (LP).
