Bowers & Wilkins Px7 S3 vs Bose QuietComfort Ultra

The Px7 S3 combines Bowers & Wilkins’ signature high‑resolution drivers with a sleek over‑ear design, offering crystal‑clear audio that rivals studio monitors. Its adaptive noise‑cancellation automatically adjusts to your environment, letting you stay immersed whether you’re on a flight or in a bustling office. Designed for all‑day comfort, the headphones feature plush leather‑wrapped ear cups, intuitive touch controls, and up to 30 hours of playback on a single charge. The companion app provides personalized EQ settings, firmware updates, and quick‑charge functionality for on‑the‑go listening.

The Bose QuietComfort Ultra Headphones combine Bose's renowned noise cancellation with a new Immersive Audio mode that adds spatialization and head tracking to any content, creating a more three-dimensional listening experience for music and movies. An updated CustomTune sound calibration technology automatically adjusts audio and noise cancellation to the specific fit and shape of the wearer's ears each time the headphones are put on. With up to 24 hours of battery life (18 hours with Immersive Audio active) and a lightweight, plush design, they are built for all-day comfort during long listening or travel sessions.
