Eargo Inc. has collaborated with battery maker VARTA AG to power the recently released Eargo 5, Eargo’s smallest and most advanced hearing aid to date. A fully customized and rechargeable battery developed by VARTA provides up to five years of running time based on usage and the highest energy density in the smallest space. Eargo 5 is fully charged within four hours for up to 16 hours of continuous power. The lithium-ion technology of the battery enables faster and easier charging while meeting the highest levels of safety. VARTA custom-developed the lithium-ion battery solution over a 15-month period and created a completely customized production line specifically for Eargo. The cell is produced climate-neutral in Germany. Eargo 5 is Eargo’s fifth generation device and is a medical-grade, FDA Class II exempt hearing device designed to be customizable to the user’s hearing needs through all new Sound MatchTM technology. Through Sound MatchTM, Eargo 5 enables at-home hearing screenings and custom tuning with no clinic visits or waiting rooms. At a fraction of the price of traditional hearing aids, it also presents a real opportunity for the estimated 43 million Americans suffering from hearing loss to take full control of their hearing health.
