Eargo is an American hearing aid manufacturer based in San Jose, California. The company's hearing aids are generally smaller and less visible than traditional in-ear devices and were inspired in their design by a fishing fly, with a small speaker surrounded by medical-grade silicone fibres (for which the company uses the trademark Flexi Fibres). Unlike many other in-ear hearing aids, the Eargo apparatus is an open-canal device that does not occlude the ear canal. Each unit is also rechargeable.
