Enjoy up to 18 hours of deep, rich sound on a single charge and a lightweight, cushioned design that lets you listen in comfort. DeepSleep mode helps conserve power when you’re not using your headphones. And when you don’t have a place to recharge, listen uninterrupted with a 3.5 mm backup jack. 40 mm drivers and advanced acoustic technology deliver audio balance and deep, rich sound—whether you’re listening to music, watching movies, or taking a call. Soft memory foam earcups not only isolate sound, they rotate to lay flat so you can wear them comfortably around your neck for hours.
