Bowers & Wilkins Pi8

The Bowers & Wilkins Pi8 sounds incredible, with 12mm carbon cone drivers and aptX Lossless delivering some of the best audio we've measured in true wireless earbuds. ANC is top-tier too, ranking in the 90th percentile. But battery life is weak, build quality is mediocre, and the $499 USD price makes it one of the least affordable options in our database. Buy it for the sound, not for the all-around package.

The sound is the whole story here, and it's a good one. Those 12mm carbon cone drivers put the Pi8 in the 86th percentile for sound in our database, which translates to one of the best-sounding true wireless earbuds on the market right now. Carbon cones are stiff and light, which means less distortion when things get loud and more precision in the high frequencies. If you listen to acoustic music, jazz, classical, or anything with real instruments, the Pi8 rewards you with detail that most earbuds just smear over. The aptX Lossless support is the other half of the equation. With a compatible phone, you're getting actual 24-bit audio over Bluetooth, not the compressed mess most wireless earbuds settle for.

But here's the trade-off. That sound quality comes with a battery that ranks in the 15th percentile. You get 8 hours per charge from the earbuds, which is fine on its own, but the overall battery story is weak compared to competitors that routinely push 10 to 12 hours. The 15-minute quick charge for 2 hours of playback helps, and the Qi wireless charging on the case is a nice touch. Still, if you're a heavy listener, you'll be topping these up more often than you'd like. The ANC is genuinely strong at the 90th percentile, and the adaptive noise cancellation does a good job of adjusting to your environment without you thinking about it. Calls are solid too, with three mics and noise cancellation on the mic side landing in the 87th percentile. Just don't expect the battery to keep up with the rest of the package.

The most direct competitor is the Technics EAH-AZ100. Technics has been chasing the same audiophile-leaning true wireless crown, and they've done it with better battery life and a more durable build. The Pi8 edges ahead on raw driver technology and that aptX Lossless support, but Technics counters with a more well-rounded package. If you want the absolute best sound and don't care about anything else, the Pi8 wins. If you want 90% of the sound with fewer compromises, the Technics is the smarter buy.

Then there's the Sony WF-1000XM6 and Apple AirPods Pro 3. Both are cheaper, both have better battery life, and both have noise cancellation that's competitive with the Pi8's 90th percentile showing. Sony's sound signature is more bass-forward and consumer-friendly, while Apple's is clean but not particularly exciting. Neither matches the Pi8's detail retrieval or high-frequency precision. The Samsung Galaxy Buds3 Pro is another option that splits the difference, with solid sound and a much better fitness story. And if you're on a budget, the Soundcore P31i exists to remind you that good enough is sometimes good enough. The Pi8 is a specialist. It beats everyone at one thing and loses to everyone at most other things.

Let's be blunt: $499 USD is a lot of money for earbuds. In our database, the Pi8 ranks in the 2nd percentile for affordability, which means almost everything else we track costs less. The Technics EAH-AZ100, Sony WF-1000XM6, and Apple AirPods Pro 3 all come in cheaper and offer better battery life, stronger build quality, and more mature ecosystems. What you're paying for here is the sound, and only the sound. If that's your priority, the price starts to make a weird kind of sense. You're getting Px8-level driver technology in a pocketable form factor, and nothing else in the true wireless space sounds quite like it.

But value isn't just about the sticker price. It's about what you give up. The Pi8 asks you to accept mediocre build quality, weak battery endurance, and a fitness score that's frankly embarrassing for a product this expensive. If you're the kind of person who buys one pair of earbuds for everything, this isn't the one. If you're the kind of person who has a dedicated pair for the gym and wants something special for focused listening, the math changes. Just know that you're paying a premium for a very specific kind of excellence.

Bowers & Wilkins has been chasing reference-grade sound in wireless earbuds for a few generations now, and the Pi8 is their most direct swing at it yet. The headline here is the 12mm carbon cone driver, lifted straight from the Px8 over-ear headphones that we've consistently ranked near the top for sound quality. That's a big driver for an earbud, and it's paired with aptX Lossless over Bluetooth 5.4, which means you're getting true 24-bit audio without a wire. On paper, this is about as serious as true wireless gets for people who care about how music actually sounds.

Who is this for? Someone who already knows what Bowers & Wilkins is, or someone who's been disappointed by the safe, bass-forward tuning on most mainstream earbuds. The Pi8 sits in that awkward space between consumer tech and audiophile gear, and it makes no apologies for it. You're not buying this for gym sessions or Zoom calls. You're buying it because you want your TIDAL subscription to actually sound like a TIDAL subscription.

The catch is that this is a $499 USD pair of earbuds in a world where the Sony WF-1000XM6 and AirPods Pro 3 exist at lower prices with better battery life and stronger ecosystems. So the question isn't whether the Pi8 sounds good. It's whether sounding this good is worth the compromises everywhere else. And spoiler: the compromises are real.

Skip the Pi8 if you need earbuds that can handle an active lifestyle. The fitness score of 33.4 out of 100 is a clear signal that these aren't built for sweat, movement, or rough handling. The build quality ranking in the 34th percentile reinforces that. If you want something for the gym or outdoor runs, the Samsung Galaxy Buds3 Pro or even the Soundcore P31i will serve you better at a fraction of the price.

You should also skip these if battery life is a dealbreaker. The 15th percentile battery ranking means you'll be charging more often than you'd expect from a $499 USD product. Heavy travelers, commuters, and anyone who forgets to charge their gear regularly will find the Sony WF-1000XM6 or Technics EAH-AZ100 much more forgiving. And if you're not already invested in high-resolution audio sources, you won't get the full benefit of what the Pi8 does best. The sound is exceptional, but it's wasted on compressed Spotify streams and YouTube videos.

If you're an audiophile who wants reference-quality sound in a true wireless form factor, the Pi8 is the closest thing to a no-brainer we've seen. The carbon cone drivers are the real deal, and aptX Lossless makes a genuine difference with the right source. Buy these, pair them with a phone that supports aptX Lossless, and stream something well-recorded. You'll get it. The ANC is also excellent, which means you can enjoy that sound in noisy environments without cranking the volume to dangerous levels.

For everyone else, the Pi8 is a harder sell. The battery life is a genuine problem for daily use, the build quality doesn't match the price tag, and the fitness score of 33.4 out of 100 means these are staying in the case when you hit the gym. If you want one pair of earbuds that does everything well, get the Sony WF-1000XM6 or the Technics EAH-AZ100. If you want the best sound and are willing to work around the compromises, the Pi8 delivers something special. Just know what you're signing up for.
