The History of Sennheiser

After realising the potential of highly growing business opportunities, applying the expertise and experience of his scientific career he started the company to meet the rising demand of measuring devices and microphones. The story of innovation which started then continues till date. Even today if you visit Sennheiser headquarters for listening sessions, product support or to get a factory visit you can sense their passion and unending energy for excellence and innovation.
