Sonova AG

Sonova AG develops and sells hearing care products and services, spanning hearing aids, cochlear implants, wireless communication systems and audiological care. The company was founded in 1947 as a Swiss startup and is now headquartered in Switzerland, with operations in more than 100 countries and over 18,000 employees. In the financial year 2024/25 it reported sales of CHF 3.9 billion and a net profit of CHF 547 million.

The group operates as a house of brands. Phonak and Unitron cover hearing instruments; Advanced Bionics covers cochlear implants; AudioNova provides audiological care; and the Sennheiser consumer hearing brand is operated under licence. Its technical work spans audio engineering and medical device development, supported by a portfolio of more than 1,800 patents and design rights.

Sonova positions its mission around a world where everyone enjoys the delight of hearing, with a stated vision of enabling people to live without limitations. Growth from a Swiss startup founded in 1947 to a global leader has been driven by continued investment in research and development.
