The Ear

Many hearing aids are ungainly; their sound can be muffled by surrounding noise. The Lyric hearing aid created by Insound Media, of Newark, California, fits deep in the ear canal, close to the eardrum, and can be worn 24 hours a day for months at a time. In addition to the high-quality sound, the devices promise users worry-free showers and comfortable sleep. The company is experimenting with a subscription-revenue model that covers replacements, upgrades, and visits to the audiologist; Insound Media charges an annual fee of $1,650, compared to the one-time price tag of $2,000 for most other hearing aid models.
