The exterior is made with a soft foam material that is specially designed to contour to your ear canal and the proprietary coating technology protects the device from moisture and ear wax.
This means that the hearing aid can be placed deep in the ear canal and sit close to your ear drum for months at a time. Lyric is a completely invisible hearing aid that can be worn 24 hours a day, 7 days a week, even while sleeping and exercising.
