Bowers & Wilkins PI6

With sound and comfort both landing in the 93rd percentile, the Pi6 deliver an audiophile experience that rivals earbuds costing much more. ANC and call quality are strong too. The main gotchas are a plasticky build, a pitiful fitness score, and some truly wacky online pricing, so stick with the $249 deal.

With a 93rd percentile score in both sound and comfort, the Bowers & Wilkins Pi6 earbuds are among the best-sounding true wireless options we've tested. Those 12mm bio-cellulose drivers, borrowed from the company's over-ear headphones, deliver rich detail and a generously wide soundstage that makes you want to re-listen to your entire library. The ANC is also a standout, clocking in at the 88th percentile, and the triple-mic setup ensures your voice comes through clearly on calls. But a total score of 80.1 out of 100 reveals some cracks: the build quality is a real letdown at the 33rd percentile, and the fitness score bottoms out at 50.2. So these are best for desk dwellers and commuters, not gym rats.

Comfort is where the Pi6 really shine. That 93rd percentile is no fluke, the earbuds feel featherlight and sit securely without fatigue, even during long listening sessions. You get all the modern connectivity you'd expect too: Bluetooth 5.4, aptX Adaptive for 24-bit hi-res audio, and multipoint for switching between devices. Battery life is a solid, though unspectacular, 8 hours from the buds and 24 total with the case, plus a quick 15-minute zap gets you 2 hours of playback. The IP54 rating means they can handle a drizzle, but don't push them too hard at the gym. At the end of the day, it's a pair of buds that nail the core experience but stumble on the details.

We don't toss around phrases like 'top-tier sound' lightly, but the Pi6 earn it. Across our entire database of true wireless earbuds, these land in the 93rd percentile for audio quality. That puts them in the same league as far pricier models like the Technics EAH-AZ100-K and the Sennheiser Momentum True Wireless 4. The 12mm bio-cellulose drivers deliver a warm, detailed profile with punchy bass that never overwhelms the mids, and the aptX Adaptive codec ensures you're squeezing every bit of data from compatible phones. Listening to well-recorded tracks, you'll pick out subtle string textures and room reverb that cheaper buds flatten into mush.

Noise canceling is another strong suit. At the 88th percentile, it's not the absolute best we've measured, the Bose QuietComfort Ultra still holds that crown, but it's close. The Pi6 effectively erase low-frequency hum from trains and AC units, and the transparency mode sounds natural enough that you can hold a conversation without pulling an earbud out. Call quality is above average too, with the triple-mic setup scoring in the 86th percentile. Wind noise can still be a nuisance outdoors, but in quieter settings you'll sound clear. The weak link? Build quality. The case and earbuds feel more plastic-y than their price suggests, and we've seen better construction from brands charging half as much.

Here's the thing about the Pi6's value: it depends entirely on where you buy them. The price spread we're seeing across vendors is absurd, from $249 at Amazon up to an almost comical $5303 from one listing. At $249, you're getting a killer deal. That kind of sound quality and comfort for under $300 puts them in direct competition with the Sony WF-1000XM5 and Bose QuietComfort Ultra, and in some areas they even win. But if you pay anything close to that high-end number, you're getting robbed. We'd never recommend them at that price. So check the store_name on the listing and make sure you're snagging the $249 deal. At that price, the performance per dollar is excellent, even with the so-so build.

Stacked against its top competitors, the Pi6 carve out a clear identity as the audiophile's choice. The Technics EAH-AZ100-K and Sennheiser Momentum True Wireless 4 come close in sound, but our data shows the Pi6 edging them out in the 93rd percentile while costing less at the $249 street price. The Sony WF-1000XM5 still wins on overall feature polish and a slicker app experience, and the Bose QuietComfort Ultra remains the ANC king. But the Pi6's comfort percentile leaves both in the dust, if long listening sessions are your priority, these are the ones to beat. Where they stumble is build quality: the Galaxy Buds3 Pro and Sony XM5 feel far more premium in hand. So it's a trade-off: you get best-in-class sound and fit, but you'll need to baby them a bit more.

Gym-goers and anyone who beats up their gear should look elsewhere. With a fitness score of just 50.2 and build quality in the 33rd percentile, the Pi6 won't survive rough handling or heavy sweat. They're also not the pick for someone who wants a premium unboxing experience; the case feels cheap. And if you can't find the $249 price, absolutely skip them, because the upper end of the price range is pure nonsense.

If you're a music-first listener who wants earbuds that disappear in your ears and deliver a truly immersive soundstage, the Bowers & Wilkins Pi6 are a fantastic pick, especially at that $249 Amazon price. The audio quality and comfort are so high that they outshine the mediocre build and weak fitness chops for a desk-and-commute lifestyle. Just be absolutely certain you're not overpaying; the wild price gaps mean you need to double-check the seller before you click buy. For the right price, these are some of the most enjoyable earbuds we've tested this year.
