Brand history<\/strong><\/span><\/div>\n
Sennheiser is a German manufacturer of such products as headphones, microphones, and other types of audio equipment. The company was founded in 1945 by Fritz Sennheiser in Wennebostel (Wedemark municipality, near Hanover) under the name Laboratorium Wennebostel (Labor W). In 1958, the company’s name was changed to Sennheiser. Initially the company produced measuring equipment, later the range was expanded to include microphones, headphones and related items. In the early years, Labor W mainly produced millivolt meters and measuring equipment for the electronics company Siemens. In 1946, Fritz Sennheiser was approached by Siemens to produce microphones. The first microphone was an exact copy of the HM 1 microphone developed by Siemens. Because Sennheiser was not satisfied with the appearance and production process of the microphone, Labor W developed the DM 2. This microphone was sold by Siemens under the name “6 S Ela 1203.” <\/p>\n

In 1948, Labor W expanded its product range. Thus they developed universal voltmeters, RLC testers, impedance testers and small test transmitters, and the knowledge of microphones was expanded. In 1949 they developed the DM 3, a microphone of small size compared to other microphones on the market. The same year Labor W developed the DM 4, the first noise-cancelling microphone. Related products that emerged during these microphone developments were simplex and duplex intercom systems. Labor W also gained another important customer. The central encryption office was looking for equipment that could track non-tappable telephone calls. Labor W developed equipment that converted voice sound into telegraphic signals, which were then divided into different bands. In this way, the signal was sent as energy and telegraphic pulses instead of frequencies. They also developed special microphones for geophysics, which could be used to detect natural gas and oil wells. From 1950, they also produced mix amplifiers and preamplifiers. From 1952, adjustable miniature magnetic headphone capsules were developed. These were used for various hearing applications and dictation machines. In 1954, Labor W marketed the first “shotgun microphone” called MD 81. This microphone could detect sound directly over a long distance. The MD 82 was later developed based on the MD 81. Twelve years after its founding, Labor W had a product portfolio of about one hundred products and accessories. <\/span><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
