Hear more of what the artist intended with the blue Px7 S2 Noise-Canceling Wireless Over-Ear Headphones from Bowers & Wilkins. Custom-designed 40mm drivers are carefully aligned and angled inside each earcup for a focused and immersive audio experience that's meant to bring you closer to the original recording. While on the go, advanced six-microphone active noise cancellation helps to ensure ambient noise doesn't distract you without negatively affecting the quality of your music. These mics are also used to provide clear hands-free calls. The Px7 S2 can provide this high-resolution playback for up to 30 hours, which goes along with a fit that aims to make extended listening extremely comfortable.
