Edifier STAX SPIRIT S10
The Edifier STAX SPIRIT S10 delivers open, detailed treble, lightning-fast planar transients and a beautifully wide soundstage that makes acoustic strings and percussion feel vividly alive. SoundStage Solo found its clarity smooth rather than harsh, while app EQ, lossless codec support and IP54 protection round out a compelling detail-first wireless listen.

Pros
Exceptionally open, detailed treble renders plucked strings and fast percussion with smooth clarity and realistic transient snap.
Beautifully wide soundstage gives acoustic guitars and layered arrangements an unusually expansive presentation.
App EQ can add deeper low-end impact, with Dynamic mode supplying bass extension that most listeners should find sufficient.
Cons
Lower midrange is somewhat subdued, and the treble-led balance may lack warmth or body for some music.
Noise cancellation only modestly reduces low-frequency travel rumble and is not competitive for isolation-focused use.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 87/100
The S10 is a lively, treble-led listen with notably clean transient detail, a wide presentation, and enough low end to avoid sounding thin. Its main tonal limitation is a somewhat subdued lower-midrange region, while listeners who prefer a warmer or more relaxed balance may want to use the app EQ.
Bass
85/100
Bass is present and extends deeply enough in the Dynamic mode, giving the S10 satisfying low-end weight for most listeners. It sits behind the treble in emphasis rather than dominating the signature, but the review found it sufficient to keep the sound from becoming hollow.
Midrange
80/100
The midrange is described as decent but slightly subdued, with a noticeable dip in the lower mids. This can reduce some vocal and instrumental body compared with the earphones' more prominent upper-frequency detail.
Treble
91/100
Treble is the S10's clearest strength, bringing brilliant detail and convincing realism to plucked strings and other fast acoustic transients. It approaches a bright presentation, but the review found it detailed without becoming harsh.
Resolution Separation
88/100
String plucks and percussion are rendered smoothly and clearly, and dense acoustic arrangements readily reveal individual instrumental textures. The S10 also brings forward details such as strumming and tambourine work, though that clarity comes with a little extra sibilance.
Soundstage Imaging
91/100
The review reports a beautifully wide stage, with acoustic guitars extending beyond the listener's shoulders. Specific comments on depth and image placement are limited, but the sense of lateral space is a standout.
Dynamics Coherence
88/100
Fast transients are reproduced with an especially realistic and responsive character, benefiting intricate acoustic material. The review does not identify any driver-integration problems or sluggishness, though it stops short of calling the planar implementation transformative.
FIT COMFORT ISOLATION PERFORMANCE 54/100
The supplied review offers no meaningful comments on shell fit, tip selection, long-session comfort, or how reliably the earphones hold their seal. Noise cancellation reduces some aircraft-like low-frequency rumble, but overall isolation is described as limited.
Seal Stability
50/100
The review says little about insertion, seal consistency, or whether movement changes bass response. There is therefore no clear evidence of either unusually dependable sealing or recurring fit problems.
Comfort
50/100
Reviewers provide no direct experience regarding shell pressure, nozzle fit, or extended-wear comfort. Comfort will depend on individual ear shape and the available tip fit.
Isolation
67/100
Noise cancellation does remove some low-end rumble typical of air travel. However, the review explicitly characterizes the overall noise cancellation and isolation performance as not great.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Accessories
72/100
The S10 has practical true-wireless ownership features including USB-C charging, IP54 protection, ANC, an app EQ, and broad Bluetooth codec support including LDAC, LHDC 5.0, and aptX Lossless. The review does not offer direct evidence on shell durability, case quality, control usability, included tips, or long-term reliability.
Value for Money
81/100
The review considers the S10 capable enough to hold its own sonically, particularly for listeners who enjoy its detailed treble presentation. It also stresses that the market contains many alternatives, making the purchase less clear-cut than the sound quality alone might suggest.

Micron-Scale Diaphragm, Light Weight and Good Transient Response
The planar diaphragm is built on a 2μm polymer substrate with a total thickness of only 10μm, ensuring a good transient response for detailed sound reproduction.
Tech Upgrade: 2nd Gen EqualMass™ Wiring
The 2nd generation of EqualMass™ wiring balances the magnetic field, ensuring equal weight distribution and uniform momentum across the diaphragm. Symmetric supporting wiring stabilizes the diaphragm, enabling piston-like motion across the audio spectrum and minimizing sound distortion.
12mm Modularized Planar Magnetic Driver
By encapsulating the planar diaphragm, push-pull magnet arrays, and damping material into such a tiny driver assembly, we ensure the uniform performance of every driver and make it possible to use a planar magnetic driver for applications such as active noise cancellation.
Production Phase Calibration
Each pair of earbuds undergoes a production-phase auto-calibration process to guarantee uniform final performance.
Qualcomm® QCC5181 Chipset
Built with Qualcomm® 2nd generation S5 Bluetooth V5.4 SoC platform, it ensures a stable connection and low power consumption, as well as improved call quality and environmental noise suppression.
Qualcomm® Adaptive Hybrid ANC
S10 uses 3rd generation Qualcomm® adaptive hybrid ANC technology.
Qualcomm® Snapdragon Sound Technology
