Bowers & Wilkins just pulled the wraps off its new flagship wireless headphones — the Px7 S3 — and there’s a lot going on under the hood. Think redesigned drivers, a dedicated amp, stronger noise-cancelling tech, and even support for spatial audio (coming later via update). It's a major step forward from the previous Px7 S2e model. But if you’re in the U.S. and itching to buy a pair, you might need to hit pause — thanks to some ongoing tariff drama.

First impressions? The Px7 S3 looks sleeker and fits better. B&W shaved down the bulk, so they’re not only slimmer on your head but also come with a smaller, more travel-friendly case. The headband has been redesigned to sit closer, and the earcups now have softer memory foam that should help with those longer listening sessions.

Bowers & Wilkins also updated the button layout — the power button now lives on the left earcup, and the playback and volume buttons have a more tactile feel. You can still control everything through the B&W Music app, but the physical buttons mean you don’t have to pull out your phone just to skip a track or toggle noise cancelling.

Inside, the upgrades are just as noticeable. The Px7 S3 comes with newly re-engineered 40mm biocellulose drivers — everything from the chassis to the voice coil and suspension has been redesigned. The idea? Less distortion, more clarity, and stronger dynamics. The drivers are still slightly angled to better line up with your ears, which helps create a more spacious, stereo feel.

One big change is the addition of a dedicated amplifier. Most wireless headphones use built-in chip amps, but B&W gave the Px7 S3 its own discrete headphone amp, designed specifically for this model. It’s meant to deliver more energy and scale, and to better match the new drivers.

Noise cancellation also got a serious upgrade. There are eight microphones in total — four to monitor external sound, two to check what the drivers are putting out, and two more focused on voice pickup. This setup aims to block out background noise without messing with your music, and make your voice clearer during phone calls.

The mic system is paired with ADI’s Pure Voice tech, which helps filter out unwanted noise during calls. Whether you’re walking through a windy street or taking a call in a noisy coffee shop, it’s designed to keep your voice front and center.

The Px7 S3 supports high-res Bluetooth codecs like aptX Adaptive and aptX Lossless, so if you’re using a streaming service like TIDAL or Qobuz, and your phone supports it, you’ll get better-than-usual wireless sound. And if you prefer a wired connection, no worries — both USB-C and 3.5mm cables are included in the box.

Later this year, spatial audio support will arrive via a firmware update, using B&W’s own processing tech. Bluetooth LE Audio and Auracast — which allow one device to broadcast to multiple headphones — are also on the way. When those updates roll out, the Px7 S3 will be one of the most future-proof headphones around.

Battery life holds steady at up to 30 hours with ANC on, and a 15-minute quick charge will give you roughly 7 hours of extra juice. That’s plenty for cross-country flights or marathon workdays.

In the UK and Europe, the Px7 S3 is already available in three colors: Anthracite Black, Indigo Blue, and Canvas White, priced at £399 / €429. In the U.S., however, it’s a different story.

Although the Px7 S3 is technically listed on Amazon in the U.S. for $429, it’s currently marked as “temporarily out of stock.” Why? It likely comes down to tariffs.

Recent import tariffs — reportedly up to 145% on goods made in China — have thrown a wrench in the U.S. release plans. Since Bowers & Wilkins manufactures these headphones in China, it’s now facing a pricing and logistics headache.

The company has said it’s reevaluating its U.S. strategy, possibly looking for new manufacturing solutions, but hasn’t given a firm release date or confirmed pricing. So, if you’re in the U.S., you’ll have to sit tight and see how things shake out on the tariff front. That said, you can head over to the Bowers & Wilkins website and sign up to be notified when the Px7 S3 becomes available—just look for the “Notify Me” button on the product page.
