STAX SPIRIT embodies the spirit of craftsmanship of STAX to produce state-of-the-art Audio products. S3 is the first in a series of high-end headphones under the STAX SPIRIT product line of Edifier.
STAX SPIRIT S3 are Edifier's flagship headphones created without compromise for stunning Hi-Res audio.
The innovative audio engineering incorporates leading audio technologies and premium components. The planar magnetic drivers produce a cleaner sound with greater resolution and better imaging that's true to professional audio recordings. The ultra-wide frequency range extends from 10Hz to 40kHz so you hear even more than before.
＊Please use devices that support Snapdragon Sound™ to achieve a high-quality wireless audio experience.
The Qualcomm® aptX™ Voice audio technology largely improves the signal-to-noise ratio, delivering 32 kHz voice call quality.
Powerful and efficient playback. A 10-minute fast charge supports 11 hours of listening.
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.
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.
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%.
The Audeze Fluxor™ magnetic structure technology and customized neodymium magnet produce double the flux density of traditional magnets and provides unparalleled efficiency.
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.
Seamless source switching for your music, games, and phone calls.
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.
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.
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.
Audeze LLC is the California-based high-end audio manufacturer delivering the most accurate sound reproduction available today. Audeze products, engineered with the latest innovations in materials science and technology, are built with precision craftsmanship. This has earned Audeze the distinction of being the world's best reviewed headphone brand. At the foundation of Audeze's award-winning audiophile sound is their cutting edge planar magnetic technology that creates an accurate, distortion free, immersive sound. Fluxor™, Fazor™ and Uniforce™ are patented Audeze technologies licensed to Edifier for STAX SPIRIT S3.

The sound is really good. But it baffles me that it is possible to make a headset in 2022, that makes continuous “plasticky sounds” every time you move you head. Walking a commuting with these is not an option for me, and I find myself using them less and less, because these sounds ruin the whole experience. I am probably more sensitive to this that’s most, but think this is something one should consider before buying these headphones. Have tried to modify with tape and even heat shrink, but without success. Fix this Edifier and you have a 5 star product. (And you should offer free repairs to us that bought sets with this fault, cause this can not be considered anything else than a engineering mishap.)
I did a ton of research on the best headphones in this price range (and above).
I had eliminated nearly every option (for one reason or another), and just stumbled upon a review of these relatively obscure offerings from Edifier. The review was very favorable, so, I did some more digging, and found only positive reviews. With the Stax pedigree to their credit, and the acquired Audeze technology, I figured it was worth a try. So, I bit the bullet, and boy was I pleasantly surprised. Amazing in every way!! Enjoying them a bunch!!!!
The STAX SPIRIT S3 is by far the best headphone I have ever tried. They are mid-range forward headphones which I personally love. They have tight bass. They have great treble. They have great separation. They have great soundstage. When they first arrived to my house the deliver person actually put it on my outside bench which is a breath of fresh air because amazon never did that, amazon would just throw it over the gate. When I opened the package i was suprised because the package had a foam covering on top and in the middle was the headphones and the under that was another foam covering and it had a cut out of the headphones box shape so they would fit in perfectly and protect them and that was the just the small box inside a much bigger box and in the bigger box it had the box that carried the headphones and the foam coverings and in the bigger box it had the headphones and the foam coverings and those "bags" that get filled with air, like the "airbags" that come with amazon packages. I was and still am happy of the care and protection that went into my headphones packaging and boxes. 5 out of 5 stars. Never change the quality of the care and protection you provide with your products. As Flossy Carter (He's a Top 5 Tech Youtuber) would say, these are a MAJOR MAJOR MAJOR GO!. In other words I highly highly recommend these.
Never regretted purchasing this.
Planar magnetic drivers are mind blowing.
Definitely recommend it to potential buyers.
I had reviewed these cans for the Amazon Vine Program back in July, giving them just three stars for their sterile, midrange-forward sound.Then my review disappeared from the product page. Had Edifier removed it?I have since been monitoring the reviews for these headphones to see if others were hearing the same harsh, fatiguing sound I was reporting.No, apparently I was in the minority.So I decided to try these cans again, reinstalling the Edifier Connect app in my Android phone.This time, I'm happy to say, the sound seems to have been improved, although I still find the midrange rather prominent and fatiguing.Previously, I could hear no difference between the three equalization settings in the app. This time I found the Classic setting warmer, closer to a sound I would expect from headphones costing this much.But when I did some A/B comparisons with the Jabra Elite 85h cans I have in the house, I still prefer the Jabra's, which also have ANC and cost $150 less.So I really can't recommend the Spirit S3's to anyone but the most rabid midrange hounds.There are just too many other great over-the-ear headphones for less money...And did I mention earbuds with better sound, ANC, and a more compact and convenient form factor? The truth is, I would prefer to wear and listen to the 1More EVO's, the Devialet Gemini's, the Sony WF-1000XM3's, or the Sudio E2's any day or night over the Spirit S3's.To summarize, then, regardless of the S3's nice packaging or high price or exotic technology, I think that this particular emperor is as naked as a jaybird!
