Annual Report 2025

In 2025, Sennheiser celebrated its 80th anniversary – eight decades of passion for sound, technological innovation and responsibility as an independent family-owned company. At the same time, the fiscal year was shaped by economic and geopolitical volatility. The Sennheiser Group remained resilient, maintained its long-term investments in research and development, and, with Spectera, brought the world’s first bidirectional wireless broadband ecosystem into the delivery phase.

But 2025 was also a year of stories beyond the business results: stories about new technologies, close collaboration, strong partnerships and the people who shape Sennheiser every day. This year’s Annual Report brings these perspectives together – and shows how Sennheiser continues to look ahead and build the future of audio.
