Behind-the-Ear (BTE)
The most popular style of hearing aid (about 60 percent of users choose this type), a BTE device is curved to match the contour of the ear and rests directly behind the ear. The housing, which contains all the electronics, is encased in plastic and connects to the ear canal with a thin, clear tube or ear mold.
Though more visible than other styles, the BTE is simple to use, making it a popular choice for children. It’s powerful enough for all types of hearing loss.
