In 2022, the U.S. Food and Drug Administration (FDA) finalized regulations allowing the sale of over-the-counter hearing aids to consumers with mild to moderate hearing loss, which opened up a market for new and existing hearing aid manufacturers to develop OTC hearing aid products.
Well-known manufacturers that currently produce OTC hearing aids include Phonak, Oticon, Austar, ReSound, and Widex, among others.
Among them, CADENZA is a professional OTC hearing aid brand, which belongs to AUSTAR manufacturer.
