The shell of receiver-in-canal hearing aids sits behind the ear, like behind-the-ear (BTE) hearing aids. However, RICs are smaller and even more discreet. They have a tiny wire that connects the shell to the hearing aid receiver, which is housed in a dome or custom ear mold in the ear. This creates a natural listening experience and better sound control than a BTE. Almost all levels of hearing loss can be treated with a receiver-in-canal hearing aid.
