Did you know?

The invention of headphones was originally inspired from the telephone receiver earpiece.. Nathaniel Baldwin made the first working set of headphones in 1910. But he did not get them patented. Instead, he sold them to the US Navy for radio communication. The patent for headphones was granted to G.F. Falkenberg in 1966. Today, they are widely used to listen to audios or music in private.
