Who Owns Sennheiser?

Fritz Sennheiser founded Laboratorium Wennebostel (later Sennheiser Electronic) in 1945 in Wedemark, Germany, initially focused on electronic measurement equipment. The company pivoted to audio electronics and microphones, establishing itself in professional broadcasting and eventually consumer audio.

Sennheiser's HD 414, launched in 1968, was the world's first open-back supra-aural headphone and introduced a design approach that influenced headphone engineering for decades. The company built a reputation for audiophile-grade headphones at accessible to premium price points.

The Sennheiser family ran the company for 76 years before the 2021 division of assets, reflecting both the pressure on mid-sized European audio companies to access capital and the divergence in strategic direction between consumer and professional audio.
