The Bowers & Wilkins Px7 S2 is a premium pair of wireless over-ear headphones released as an upgrade to the original Px7. As of 2026, it has been largely succeeded in the primary retail market by the Px7 S2e ("evolved"), though the S2 remains highly regarded for its build and audio performance. Offers up to 30 hours of playback on a full charge. A 15-minute quick charge provides an additional 7 hours of use. Features hybrid Active Noise Cancellation (ANC) with six microphones—four for noise isolation and two for voice clarity during calls. Built with premium materials, including memory foam earpads and technical fabric finishes. Uses Bluetooth 5.2 and supports USB-C for both charging and high-res wired audio pass-through. Uses custom-designed 40mm cellulose drive units, angled for a more immersive soundstage.
