Company

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

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.

Sennheiser is headquartered in the municipality of Wedemark, Germany (near Hannover). Its United States headquarters is located in Old Lyme, Connecticut.
