PX uses built-in sensors to enhance the way you instinctively use a set of headphones. Put them on your head and they’ll switch on: take them off and they’ll return to stand-by mode. Lift an ear cup to talk or hang them round your neck and PX will pause the music, resuming playback when you’re ready to listen. It’s as if the headphones are an extension of you, anticipating your needs.
