Get next-level high-fidelity audio perfect for every music audiophile, both passionate and professional.

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 reproduce 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 the distortion to 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 provides 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 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 ultimate listening expericence.

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

Qualcomm® aptX™ Voice Crystal Clear Call Guaranteed
