1910 – Nathaniel Baldwin began manufacturing the first modern headphones. He crafted them in his kitchen and sold them all to the U.S. Navy. This was the first time a pair of cans resembled something you’d see today. Baldwin never patented them. Patented is when you claim your invention and when ever one is sold you get some of the money.
1937 – The DT-48’s from Beyerdynamic became the first dynamic headphones to hit the market. Though it would be a few decades before electrostatic headphones came into play, this was obviously a huge leap forward in the can story. Dynamic headphones are, to this day, the most popular type on the market.
1949 – With design in mind, AKG produced their first pair of headphones, the K120’s.
