Edifier STAX SPIRIT S5

The Edifier STAX SPIRIT S5 are wireless over-ear headphones with planar magnetic drivers that deliver the best sound quality we've ever measured in a Bluetooth pair. You get an insane 80-hour battery and every high-res codec you could want, but you trade away active noise cancellation and all-day comfort. It's a niche masterpiece for audiophiles, not a daily driver for commuters.

Let's cut to the chase: the sound quality here is the absolute best right now for wireless over-ears. In our database, it sits at the 100th percentile, and it's not just a numbers game. The planar magnetic driver delivers a speed and clarity that dynamic drivers in this price range just can't match. Bass is tight and textured, not bloated, and the treble has a sparkle without getting harsh. The soundstage is wide enough to make you forget you're listening to a closed-back pair. If you feed it a lossless track over LDAC or aptX Lossless, it's a genuine 'wow' moment.

Battery life is another standout at 80 hours, landing in the 95th percentile. That's nearly double what you get from the Sennheiser Momentum 4 and triple the Bowers & Wilkins Px8 S2. The quick charge is practical too: 10 minutes gets you 11 hours of playback. Connectivity is also top-tier, with Bluetooth 5.4 and multipoint that switches between devices without a fuss. The microphone performance is well above average, thanks to the dual-mic setup with aptX Voice, so calls come through clear even if you're not in a silent room. But the ANC score tells a different story. At the 63rd percentile, the noise isolation is just okay. It relies on passive isolation from the closed-back design, which is fine for a quiet office but won't silence a subway rumble.

Stacked against the Sony WH-1000XM6, the choice is pretty stark. The Sony is the king of commute and travel with class-leading ANC and a lighter, more comfortable fit. But its sound, while good, is a processed, bass-forward take that can't touch the raw detail of the S5's planar driver. The Sennheiser Momentum 4 splits the difference better, with a rich, engaging sound and solid ANC, but its battery life is half of the Edifier's. The Bowers & Wilkins Px8 S2 feels more premium in the hand and sounds excellent, but it's pricier and still uses a dynamic driver that lacks the planar speed. If you're considering the Bose QuietComfort Ultra, you're clearly prioritizing comfort and silence over absolute fidelity, and the S5 will feel like the wrong tool for that job. The JBL Live 770NC is a budget alternative that gets you decent sound and ANC for a fraction of the cost, but it's in a completely different league sonically.

Pricing on the S5 is all over the map, with a spread of over $12,000 across vendors, which is frankly ridiculous. The realistic street price sits around $400 to $500, and at that level, you're getting planar magnetic sound that no other mainstream wireless headphone offers. The Bowers & Wilkins Px8 S2 costs more and sounds less detailed, while the Sony WH-1000XM6 gives you far better ANC and comfort for a similar price. If pure sound quality is your only metric, the S5 is a steal. But you have to accept that you're paying for audio performance and battery life while sacrificing the creature comforts and noise-blocking that most people expect at this price. For the best deal, keep an eye on Amazon where it tends to hover near the lower end of that range.

The Edifier STAX SPIRIT S5 is a bit of an oddball in the wireless headphone world, and that's exactly what makes it interesting. Most over-ear Bluetooth cans chase the same formula: active noise cancellation, bass-heavy tuning, and a design that screams 'tech gadget.' The S5 flips the script. It's built around a planar magnetic driver, the kind you'd normally find in chunky wired headphones for critical listening, and it skips ANC entirely in favor of a transparency mode. If you've been hunting for a pair of wireless headphones that actually sound like high-end wired ones, this is the shortlist.

The spec sheet reads like an audiophile's wish list. You get support for LDAC, LHDC, and the full suite of aptX codecs including Adaptive and Lossless, all running on Bluetooth 5.4 with Snapdragon Sound. Edifier even throws in a 3.5mm jack and a USB-C wired mode for good measure. The 89mm planar driver uses their 2nd Gen EqualMass tech with a 2μm thin film, and the whole thing is wrapped in lambskin and cowhide earcups. It's a serious piece of kit aimed squarely at people who care about sound quality first.

But here's the catch: the S5 is not a do-it-all headphone. Our database shows it's a champ for music and decent for gaming, but it stumbles hard for commuting. The lack of ANC and some comfort quirks mean this isn't the pair you grab for a noisy flight. At around $400 to $500 from most vendors, it's priced against heavy hitters like the Sony WH-1000XM6 and Bose QuietComfort Ultra. You're trading noise cancellation and all-day plushness for a sound signature that's genuinely best-in-class for wireless.

Skip the Edifier STAX SPIRIT S5 if you need a headphone for your daily commute or noisy office. The lack of active noise cancellation and the mediocre passive isolation make it a poor fit for travel. Comfort is also a weak spot, so if you wear headphones for hours on end, the clamping force and weight will likely bother you. Anyone who wants a premium, tank-like build should look elsewhere too; the plastic components feel a step down from the price. For a better all-rounder with ANC, grab the Sony WH-1000XM6 or the Sennheiser Momentum 4. If you want planar sound but need isolation, consider a wired pair with a portable DAC instead.

Should you buy the Edifier STAX SPIRIT S5? If you're an audiophile who has been waiting for a wireless headphone that doesn't compromise on sound, the answer is a resounding yes. This is the pair for someone who listens to FLAC files at home, wants to ditch the cable, and doesn't care about blocking out the world. The planar magnetic driver is the real deal, and the codec support means you're not leaving any detail on the table. It's a specialist's tool, and in its specialty, it's untouchable.

But for most people, the S5 is a tough sell. The lack of ANC is a dealbreaker for commuters and office workers. The comfort issues, with a 10th percentile ranking in our database, mean you might not want to wear these for a full workday. And the build quality, with reports of fragile plastic, doesn't inspire confidence for a $400-plus product. If you need one headphone to do everything, get the Sony WH-1000XM6. If you want the best wireless sound money can buy right now, the S5 is it.
