Qualcomm® aptX™ Voice Crystal Clear Call Guaranteed

The Qualcomm® aptX™ Voice audio technology largely improves the signal-to-noise ratio, delivering 32 kHz voice call quality.

80 Hours of Ultra-Long Playback

Powerful and efficient playback. A 10-minute fast charge supports 11 hours of listening.

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.

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%. 

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.

Multi-Point Connectivity

Seamless source switching for your music, games, and phone calls.

Expanded Audio Experience:

Get even more from your listening with the Edifier Connect App. Access the ‘Classic,’ ‘Hi-Fi,’ and ‘STAX’ EQ modes for varied sound experiences. Switch to gaming mode for low-latency audio. Customize many other settings to suit your needs.

All-Day Comfort:

An ultra-light and durable carbon fiber casing with fully foldable hinges makes wear and carry easy. The genuine lamb leather headband & earpads offer a touch of luxury. Alternative cooling mesh gel earpads are also included.

Connect Any Way You Want

In addition to the Bluetooth 5.2 connection, the STAX SPIRIT S3 also comes with an Aux-in cable and a 3.5mm to 6.35 adaptor for wired connection.

In 2012, Edifier acquired STAX Ltd., a company with a history of more than 80 years 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.
