Microsonic

Microsonic is a private U.S. hearing-health company that manufactures custom earmolds, hearing protection products, and related audiology supplies. Founded in 1964, the company serves audiologists and the broader hearing health market with handmade and digitally produced earmolds, including products enabled by 3D ear-scan workflows and in-house 3D printing. Its portfolio includes custom earmolds for hearing aids, custom hearing protection, sleep plugs, communications molds, and accessory products. The business appears to be commercially focused rather than drug-development oriented, with ISO 9001 and ISO 13485 certified facilities in the U.S. and Europe. Microsonic is led by Monika Major and remains an active family-operated company headquartered in Ambridge, Pennsylvania.
