Sennheiser MD431II Profipower B-Stock

The Sennheiser MD431II is a moving-coil microphone with a supercardioid polar pattern and an astonishingly wide frequency range of 40Hz to 18kHz. Although the Sennheiser MD431II is a traditional dynamic microphone, its response is exceptionally good, with levels we might otherwise only expect from condenser microphones. When used at close range, it offers a pronounced proximity effect that lends voices a special intimacy and richness. Singing at a greater distance from the microphone capsule will mean losing some of that tender, intimate sound, which is however more than made up for by the mic's clear, bright response at this distance, with articulate and finely detailed mids and highs.

In June 1945, Prof. Fritz Sennheiser founded the Wennebostel Laboratory, which initially produced measuring equipment. Commissioned by Siemens in 1945, the young company developed the MD-1 microphone, which was launched in 1946. After the development of further microphones, the company was renamed Sennheiser Electronic in 1958. Two years later, Sennheiser introduced the MD 421 dynamic microphone, which is still in production today and still held in high esteem by many sound engineers. Further groundbreaking developments, such as the HD 414 headphones and the classic MD 441 microphone, hugely enhanced the company's international reputation, eventually making Sennheiser one of the leading manufacturers of microphone and headphone systems in the world.
