Let’s reinvent the future of better hearing together

WS Audiology was founded in 2019 through the merger of Sivantos, headquartered in Singapore, and Widex, headquartered in Lynge, Denmark. Today, the company, of which Sivantos is a subsidiary, employs more than 10,000 people worldwide, is active in over 125 markets and generates annual sales of more than 1.7 billion euros. WS Audiology offers a broad portfolio of hearing aids and services through its brands, which include Signia, Widex, Rexton and Audio Service.
