Top quality sound element

Hand selected thin-film diaphragm as well as tough stainless fixed electrodes has been employed for the SR-L300. Thus, rich deep bass response, delicate high frequency and soothing mid-range has been achieved in a balanced manner.

Japanese manufacturer STAX have been developing headphones since 1938 and electrostatic headphones since 1959. Utilising electrostatic technology in their ‘earspeakers’ that are widely regarded as the best headphones available today, STAX electrostatic earspeakers are widely used throughout the world by discerning audiophiles, professional musicians, and recording companies to enjoy and monitor sound thanks to the superb sonic quality that they offer.

An electrostatic transducer is a speaker design that employs a high polymer film of several microns thick as the diaphragm for far less mass than paper or mylar cones or metal type diaphragms. Since electrostatic elements use no magnets, they are free from magnetic hysteresis distortion that is prominent in dynamic type headphones.
