When Fritz Sennheiser founded the company in 1945, he started a venture that we call today a “start-up”. While the company didn’t start in a garage, the story very closely resembles the classic start-up tale, with the venture initially founded in a farmhouse near Hanover. Fritz Sennheiser soon discovered fast-growing business opportunities, using the knowledge and skills that he gained in his prior scientific career to respond to a high demand for measuring devices and microphones.
This was just the start of a story of innovation and the pursuit of new ideas. Today, the story continues: When you visit our headquarter for listening sessions, product consultation or for a factory tour, you can still feel the same passion and an unceasing drive for excellence and discovery.
1945-1982: Foundation of the company by Prof. Dr. Fritz Sennheiser
Fritz Sennheiser founded the Laboratorium Wennebostel (Labor W, which translates as Lab W) in June 1945. At the time of its foundation, the young company produced measuring instruments and sold them to Siemens. The farmhouse where the company was founded is still part of our business premises. The company was renamed in 1958 to Sennheiser electronic and changed its legal form to Sennheiser electronic GmbH & Co. KG in 1996.
In 1945, Siemens commissioned the laboratory to rebuild a microphone from an Austrian supplier, which was launched in 1946 as the MD 1. In the same year, Sennheiser began developing its own microphone: The MD 2 expanded the company's portfolio from 1947.
The MD 82, the first shotgun microphone, was produced in 1956. At the beginning of the 1960s, Sennheiser commenced research and development in the field of condenser microphone technology, a technology that found further applications in recording audio for film sets and TV studios.
In 1957, Labor W introduced a wireless microphone system for professional TV use, developed in cooperation with NDR. The wireless microphone system was marketed together with Telefunken from 1958 as “Microport”.
In 1960, Sennheiser introduced the MD 421 dynamic microphone, which is still produced and sold today.
In 1968, Sennheiser launched the HD 414, the world's first open-back headphones, which remain the bestselling full-size headphones of all time. Did you know that we still stock spares of the cables and iconic yellow ear pads?
1971: The MD 441 is introduced: the model has gone on to become a microphone classic.
Sound became spatial in 1974: The MKE 2002 head-worn stereo microphone enables binaural audio recordings according to the dummy head principle.
At the end of the seventies, the first Microport multi-channel receiver and the development of a compander system contributed to a decisive improvement in wireless microphone technology.
1982 to 2012: Internationalization under Prof. Dr. Jörg Sennheiser
In 1982 Prof. Dr. Fritz Sennheiser handed over the management of the company to his son, Prof. Dr. Jörg Sennheiser.
1988 was the starting point for the internationalization of the family business: The first sales subsidiary, Sennheiser France, was founded. Over time, further subsidiaries were launched; Nowadays, we have 21 subsidiaries worldwide.
1988: The HD 25 headphones enter the market. Originally conceived as professional monitoring headphones, they were also used as high-class in-flight headphones on board Concorde, before going on to conquer DJ booths the world over. In 2013, we marked the 25th anniversary of the HD 25, revisiting and celebrating the history of these legendary headphones.
Sennheiser took over the Berlin studio microphone manufacturer Georg Neumann in 1991, integrating its microphone production into Sennheiser’s own factory in Wennebostel.
In 1991, the Orpheus electrostatic headphones entered the market. The limited-edition model was considered the best headphones in the world for decades. In 2015, Sennheiser presented the HE 1 as the successor to the legendary Orpheus.
1998: The evolution microphone series was launched, followed by the evolution wireless microphone series in 1999. Up to this very day, many of the world’s biggest stars are using our evolution microphones– a runaway success that we celebrated on reaching "20 years of evolution" in 2018.
