Built from legend The 43.6mm drivers in the PX7 are the largest in our headphone collection and are developed and tuned by the same engineers behind the Bowers & Wilkins 800 Series Diamond loudspeakers found in Abbey Road Studios. Cancels noise clean out Adaptive noise cancelling that automatically responds to your environment, keeping the outside world out of the music. 30 hours of flight You can do a lot in 30 hours. Fly from San Francisco to London and back, with time to spare. See every band at the festival, twice. Listen uninterrupted on a single battery charge. And if that's not enough, a 15-minute quick charge gets you five more hours. Follows your lead The PX7 obeys your every move. Lift an ear cup to hear what's happening around you and the music automatically stops. Put it back and the music plays on. Inspired by racing cars The woven carbon fibre composite arms of the PX7 mimic the strength and agility of the fastest vehicles in the world, channeling pure sound to you and holding up against everyday wear and tear. Throw them in your bag and get ready to jump into sound.
