Founded in 1924 by Eugen Beyer as 'Elektrotechnische Fabrik Eugen Beyer' in Berlin, Beyerdynamic revolutionized audio with cinema loudspeakers for emerging film palaces. Born in St. Petersburg (1903), Beyer moved to Berlin in 1921, captivated by moving pictures and determined to enhance them with sound. The company pioneered the world's first mass-produced dynamic headphones, the DT 48, in 1937, followed by innovations like the M 160 ribbon microphone (1957) and the first wireless 'transistophone' (1962). After WWII damage, production relocated to Heilbronn near Stuttgart in 1948, where the family-owned company remains headquartered. Celebrating 100 years in 2024, Beyerdynamic continues manufacturing over 85% of their headphones and microphones in Germany. From Eugen Beyer's cinema vision to modern wireless systems and conference technology, the company represents German engineering excellence in professional and consumer audio markets worldwide.
