Specially developed 35 mm drivers, created and tuned by the same team behind the Diamond Series 800 speakers used in Abbey Road Studios, deliver music in all its glory. From the library to Grand Central Station, the adaptive noise cancellation automatically adjusts to keep unwanted noise out of your sound. A single battery charge provides just over a full day of music. If you need more power, a 15-minute quick charge allows for five hours of audio playback. The PX5 obeys your every move. Lift an ear to hear what's happening around you, and the music automatically pauses. Put it back, and the music continues. The woven arms of the PX5, made from carbon fiber composite, mimic the strength and agility of the world's fastest vehicles, channeling pure sound to you while standing up to everyday wear and tear. These headphones easily fit in your pocket, allowing you to immerse yourself in sound wherever you go.
