InSound Medical Lyric Hearing Aid

The Lyric hearing aid is the first you can wear for months straight without surgical implantation. The bean-size device stays inside your ear canal even when showering and sleeping, for up to four months. Sitting just a sixth of an inch from the eardrum, closer than any other hearing aid, it maximizes use of the entire outer ear to capture sound naturally. On the speaker end, the short distance to the eardrum reduces distortion. The user adjusts volume levels or turns it on or off by holding a small magnetic wand up to it. Patients replace the used Lyric every three to four months during a quick visit to the audiologist.
