beyerdynamic was founded in Berlin in 1924 by Eugen Beyer, a Russian-born engineer whose fascination with early cinema drove him to develop loudspeakers that could give moving pictures a voice. From those beginnings, the company introduced the DT 48 in 1937 — the world’s first dynamic headphone — and the M 19 studio microphone in 1939, establishing a complete audio transmission chain that still defines the brand over 100 years later. Today, beyerdynamic remains headquartered in Heilbronn, Germany, where over 400 employees hand-build headphones and microphones to exacting standards and distribute them to professionals and audiophiles in more than 100 countries. The DT 770 PRO has long been a benchmark for studio monitoring, and that same commitment to honest, uncompromising sound runs through everything beyerdynamic makes.
