Yes, there are a variety of hearing aids that are invisible, including IIC (Invisible in-the-canal) hearing aids and LYRIC. Lyric is an extended wear hearing aid that is completely invisible (similar to contact lenses for the eye), and stays in a persons ears for approximately 2 months. There are no batteries to change, and you can shower and sleep in them. They are much cheaper than regular hearing aids and are subscription based. Most people report they enjoy the sound quality much more because the device uses the natural acoustics of the ear canal to funnel sound into the ear.
