History
In the 1920s in Berlin, founder Eugen Beyer believed that cinema presented a new opportunity in communication media.[1] The first products he produced were loudspeakers for film palaces in 1924[3] under the company name "Elektrotechnische Fabrik Eugen Beyer". At the end of the 1930s, Beyer developed the first pair of dynamic headphones, the DT 48 (“Dynamic Telephone”).[1]
