STAX was founded in 1938. In 1959, STAX developed the world’s first electrostatic headphone and introducedtheSR-1 in 1960. Today STAX continue their tradition by offering the finest headphones for both professional and audiophile applications. STAX refers to all its headphones as “Earspeakers”. Such Ultra-High-Fidelity devices for reproducing music can only be compared with the best cost-no-object loudspeakers, not other headphones. The term “Earspeaker” is, therefore, more descriptive of STAX’s contribution to today’s most advanced level of sonic transduction.

STAX is a company with more than 80 years of history and a persistent pursuit of Hi-Fi and Hi-Res audio reproduction. It has always focused on electrostatic technology and has almost become synonymous with electrostatic headphones. In 2012, Edifier acquired STAX Ltd and started to expand the company’s portfolio with the introduction of portable Planar Magnetic headphones.
