PX7 Wireless Over-Ear Noise-Canceling Headphones (Silver)
Product Description
The silver PX7 Wireless Over-Ear Noise-Canceling Headphones from Bowers & Wilkins are Bluetooth headphones equipped with adaptive noise cancellation technology that automatically responds to your environment to keep the outside world out of the music. They can be used to take calls and playback music from your smartphone, tablet, iPod, or laptop computer. Listen uninterrupted on a single battery charge for up to 30 hours. If you need more time, a 15-minute quick charge gets you 5 hours of playback.
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.
