Ultra-Low Distortion Planar Magnetic Drivers

Compared to traditional dynamic driver headphones in the market, the STAX SPIRIT S3 comes with advanced planar magnetic drivers that lower audio distortions and wider dynamic responses.

EqualMass™ Diaphragm Technology Engineered for Extreme Accuracy

The all-new Edifier EqualMass™ diaphragm technology combines trusted and iconic components, including the Audeze® Fluxor™ magnetic structure, Uniforce™ diaphragm, and Fazor™ phase management, accurately reproducing the original sound.

Uniforce™ Diaphragm - 0.5% Imperceptible Distortion

The Uniforce™ technology is designed to achieve and deliver uniform driving force to produce unparalleled acoustic details and accuracy with distortion to an imperceptible 0.5%.

Fluxor™ Magnetic Structure - Higher Definition and Wider Frequency Response

The Audeze Fluxor™ magnetic structure technology and customized neodymium magnet produce double the flux density of traditional magnets and provide unparalleled efficiency.

Fazor™ Phase Management - How It's Meant to Sound

With Fazor™, sound waves generated by planar magnetic diaphragms pass through magnetic structures without disturbance, preserving timing details in the recorded signal. This ultimately results in a cleaner sound, greater resolution, and better imaging.

Hi-Res audio and Qualcomm® Snapdragon Sound™

Combination of Snapdragon Sound™ audio technology with planar magnetic headphones for the ultimate listening experience. 

＊Please use devices that support Snapdragon Sound™ to achieve a high-quality wireless audio experience.
