? The man behind the invention of the first modern headphones was the American engineer Nathaniel Baldwin from Utah. It was said he made the first pair - a headset that could amplify sound - by hand in his kitchen in 1910. When his idea was dismissed by private investors he turned to the military. It turns out that the navy was interested in the invention and ordered 100 pairs. Baldwin became wealthy from his contract with the navy, but he never patented his invention.
? In 1937 it was Eugene Beyer that created the Beyerdynamic DT-48 model of the first dynamic driver headphones for monitoring and home listening in Berlin in Germany. In 1949 the company AKG from Vienna in Austria focused on headphone design when creating they model K120.
? And lastly it was John C. Koss, who is credited with creating the first stereo headphones Koss SP-3 in Milwaukee in Wisconsin 1958. He was a big Jazz lover and his goal was to produce headphones exclusively for listening to music.
? Not much is know about Gustave F. Falkenberg who submitted the patent for the headphone assembly in 1963, and was approved in 1966. He did not patent the driver technology though. The patent was assigned to a company in Brookfield, Wisconsin called Dimensional Products Inc. He also patented a design for an illuminated display, and a dispenser for bottled liquids amongst others.
