This is a Sennheiser headphones review. Sennheiser is a private, family-owned German company, started in Germany in 1945 shortly after the Second World War. It produces all kinds of electronic equipment for business, professional, and private use. They began by making microphones, telephone accessories, and, of course, different kids of headphones and headsets, including avionic headsets.
In 1968 Sennheiser started to produce the HD 414, which was the first set of open headphones. Eventually more than 10 million units of the Sennheiser HD 414 were sold, making it to this day the best selling headphone product of all time. Many headphone companies have copied the Sennheiser open back headphone style because of its natural sound stage and imaging properties.
Today Sennheiser has one of the very largest and most diverse inventories that can be found anywhere of headphones, headsets, earphones, and wireless microphones. Unlike certain other headphone companies which specialize in a very limited selection, Sennheiser tries to provide a wide selection for any need. It would be impossible to display and review all of them in one short article, but listed below are some of the most popular models.
