The PX7 Wireless features smart sensors to enhance how you use them. Lift an earcup to hear what’s happening around you, and the music automatically stops. Put it back, and the music plays on. The woven carbon fiber composite arms are durable to hold up against everyday wear and tear. A headphone case, a 3.5mm audio cable, and a USB Type-C charging cable are also included. The 43.6mm drivers in the PX7 headphones are built and tuned by the same engineers behind the Bowers & Wilkins 800 Series Diamond speakers used in Abbey Road Studios. Listening in a library or in Grand Central Station, adaptive noise cancellation automatically adjusts to keep the outside world out of the music. One battery charge and you can listen to over a full day of music up to 30 hours. If you need more power, a 15-minute quick charge provides five hours of audio playback.
