The Edifier STAX SPIRIT S3 Wireless Headphones represent a new generation of high-performance wireless audio, combining advanced planar magnetic driver technology with premium wireless connectivity. Developed under the STAX SPIRIT range, these headphones are designed for listeners who demand exceptional sound clarity, accurate detail, and long-lasting comfort. With up to 80 hours of playback, Hi-Res audio support, and cutting-edge acoustic engineering, the STAX SPIRIT S3 delivers an immersive listening experience that reflects true audiophile standards.
Inspired by Legendary Audio Engineering
Edifier’s STAX SPIRIT series draws inspiration from the legacy of STAX Ltd., a renowned Japanese manufacturer with more than 80 years of expertise in high-fidelity audio and electrostatic headphone technology.
To further elevate performance, Edifier has integrated licensed technologies from Audeze LLC, one of the world’s most respected high-end headphone manufacturers. These advanced innovations—including Fluxor™, Fazor™, and Uniforce™ technologies—help deliver highly accurate, distortion-free sound reproduction.
Planar Magnetic Drivers for Exceptional Audio Precision
Unlike traditional dynamic drivers, planar magnetic drivers use an ultra-thin diaphragm suspended between magnetic arrays. This design allows the diaphragm to move evenly across its surface, resulting in faster response times and significantly reduced distortion.
The large 89mm × 70mm planar magnetic drivers inside the STAX SPIRIT S3 produce rich, detailed audio with impressive dynamic range, making them ideal for high-resolution music playback.
EqualMass™ Diaphragm Technology
Edifier’s proprietary EqualMass™ diaphragm technology ensures balanced distribution of weight and driving force across the entire diaphragm surface. This improves stability and allows the driver to reproduce audio signals with greater accuracy.
Combined with Audeze technologies such as Fluxor™ magnetic structures and Uniforce™ diaphragm design, the headphones achieve extremely low distortion levels—down to approximately 0.5%, delivering remarkable sonic precision.
Hi-Res Audio with Snapdragon Sound™
The STAX SPIRIT S3 supports Hi-Res Audio playback and integrates Qualcomm’s advanced wireless audio technology for premium sound quality.
Built with support for the Snapdragon Sound™ platform, the headphones enable high-quality Bluetooth transmission with minimal latency and enhanced clarity when paired with compatible devices.
Supported codecs include:
• Qualcomm® aptX™ Adaptive
• Qualcomm® aptX™ HD
• Qualcomm® aptX™
• SBC
These codecs ensure clear, high-resolution wireless playback across a wide range of smartphones, tablets, and computers.
Wide Frequency Range for Greater Detail
With a frequency response extending up to 40kHz, the STAX SPIRIT S3 captures subtle details often missed by standard headphones. From deep bass tones to delicate high-frequency textures, the headphones reproduce music with impressive realism and balance.
Up to 80 Hours of Playback
A powerful 1500mAh battery allows the headphones to deliver up to 80 hours of listening time on a single charge. This extended battery life makes them ideal for long journeys, daily commuting, or extended listening sessions.
A 10-minute fast charge provides approximately 11 hours of playback, ensuring you can quickly return to your music when the battery runs low.
Clear Calls with aptX™ Voice Technology
Integrated microphone technology combined with Qualcomm aptX™ Voice improves voice clarity during calls. The enhanced signal-to-noise ratio helps ensure conversations sound natural and clear, even when using Bluetooth connections.
Multipoint Connectivity for Seamless Switching
The STAX SPIRIT S3 supports multipoint Bluetooth connectivity, allowing two devices to remain connected simultaneously. This makes it easy to switch between music, gaming, and calls without manually reconnecting each device.
Personalised Listening with the Edifier Connect App
Using the Edifier Connect App, users can customise their listening experience with several preset sound profiles. Choose from Classic, Hi-Fi, or STAX EQ modes, or adjust other settings to suit your personal preferences.
The app also provides additional control options and performance features, including low-latency gaming mode.
Lightweight Comfort for Extended Listening
Designed for all-day wear, the headphones feature a lightweight carbon fibre structure that balances durability with comfort. Genuine lamb leather ear pads and headband provide a soft, premium feel, while maintaining excellent acoustic sealing.
For warmer environments or travel, an additional set of cooling mesh gel ear pads is included to keep listening comfortable during long sessions.
Flexible Wired and Wireless Connectivity
In addition to Bluetooth connectivity, the headphones support wired listening via AUX input, making them compatible with a wide range of audio devices. A 3.5mm cable and 6.35mm adapter are included for easy connection to amplifiers, audio interfaces, and professional equipment.
