Eargo is an American hearing aid manufacturer. Eargo produces hearing devices that are built with a small speaker surrounded by silicone fibers. The design is modeled after the standard fishing fly and is a certified Class 1 medical device. The medical-grade silicone fibers (called Flexi Fibers) allow natural bass sounds to flow more freely into the ear canal. Many other in ear hearing aids occlude the ear canal, but the Eargo apparatus is an open-canal device that is designed to provide more airflow, comfort, and to allow ambient bass sounds to pass through.
The devices come in 2 different sizes and are pre-programmed with 4 standard profiles. Users can also send their personal audiograms to licensed hearing professionals at Eargo who will custom-calibrate the device for that individual's specific needs. The settings for the device in one ear can be changed independently of the device in the other ear. The hearing aids can be charged using a portable charging device included with the Eargo devices. The hearing devices are designed to hold a charge for up to 16 hours.
