Massachusetts Institute of Technology professor of electrical engineering Dr. Amar G. Bose founded Bose Corporation in 1964 after being disappointed with the sound quality of a newly purchased stereo. Four years later, he introduced a speaker system that came close to reproducing the experience of live music. Today, the company manufactures music and home theater systems, and loudspeakers for the home, vehicles and professional venues. Bose also makes noise reduction headsets for aviation and consumer use. In April 2011, Amar Bose donated his stake in the Bose Corporation to MIT. The university does not have any role at the company.
