Profile: InSound Medical, Inc., is a developer and manufacturer of Lyricr hearing aids. It is the only 100% invisible extended wear hearing device. Lyric can be comfortably placed in the ear canal without surgery. It can be positioned completely inside the ear canal to give natural sound quality & effortless hearing. It allows patients to enjoy the benefits of better hearing without anyone ever knowing they're using a hearing device. Lyric's design and placement allow it to reside deeper in the bony portion of the ear canal than traditional hearing aids, thus minimizing the occlusion effect. It is anchored in the ear canal with two soft, compliant seals that conform to irregular shapes and contours of various ear canals, even when the ear changes shape during chewing and talking. This prevents slippage of the device which, with traditional hearing aids, causes gaps to form between the aid and the canal wall resulting in sound leakage and feedback.
