For those with hearing loss, hearing AIDS are the only way to help them return to the noisy world. But hearing AIDS are usually expensive, and at $4,200 a pair in the United States, not everyone can afford them. But Eargo is likely to be the future of hearing aid. Compared to traditional hearing AIDS, Eargo's hearing aid USES an invisible design. On the outside, Eargo looks more like a fish taking off, and its unfurled "wings" are a special fibrous material that helps the hearing aid stay outside the ear canal. And, more importantly, these expanded fibers don't clog up the entire ear canal. This design not only ensures the effective transmission of sound, but also increases the air permeability of the whole ear canal and makes the wearing comfortable. What's more, Eargo hearing AIDS are affordable and affordable for all. Eargo hearing AIDS allow hearing-impaired patients to return to the audio world as soon as possible without the constraints of appearance, lifestyle or even wallets.
