The Sennheiser e845s microphone

Founded as Labor W and family-owned since 1945, Sennheiser has 2,100 employees,[1] 60% of them working in Germany.[2] Major subsidiaries of the company are Georg Neumann, which builds studio microphones, and Klein + Hummel, a producer of high-quality studio monitors. In 2003 Sennheiser Communications A/S, Denmark was announced, a joint venture between Sennheiser electronic and William Demant, to develop and produce telecommunications products. In 2006, revenues of Sennheiser totaled € 300 million.[3]

History[edit]

The company was founded in 1946, just a few weeks after the end of World War II, by Fritz Sennheiser (1912–2010)[4] and seven fellow engineers of the University of Hannover in a laboratory called Laboratorium Wennebostel (shortened, "Labor W"). The laboratory was named after the village of Wennebostel, where it had been moved to due to the war. Its first product was a voltmeter. Labor W began building microphones in 1946.

By 1955, the company had 250 employees. Labor W was renamed 'Sennheiser electronic' in 1958. Sennheiser was transformed into a limited partnership (KG) in 1973. In 1980, the company entered the aviation market, supplying Lufthansa with headsets.[5] The company began producing modern wireless microphones in 1982, the same year when founder Fritz Sennheiser handed the management of the company over to his son, Jörg Sennheiser.

Locations[edit]

Sennheiser is headquartered in the municipality of Wedemark, Germany (near Hannover). Its United States headquarters is located in Old Lyme, Connecticut. The company has factories in Burgdorf, Germany; Tullamore, Ireland (since 1990); and Albuquerque, New Mexico (since 2000). Sennheiser's R&D facilities are located in Germany and San Francisco, California. Sennheiser has sales branches in France, the UK, Belgium, the Netherlands, Denmark, India, Singapore, Canada, Argentina, Mexico and the USA.
