Powered by a pair of included AAA batteries, the noise cancellation feature in a pair of stylish Beats Studio headphones amplifies the music as it blocks out noise, giving you consistently powerful and intense sound. Super plush and covered with ultra-soft breathable materials, you'll be cool and comfortable even during marathon listening sessions. The Beats by Dr. Dre logo on the side also acts as a mute button when you press it. No need to take them off to talk. Designers of Beats Studio headphones conducted a series of ergonomic studies to find the perfect lightweight, foldable heaphone that always delivers a comfortable fit. Take calls, skip songs and adjust volume right from the cord of your Beats Studio headphones. No more searching for you phone or music player just to find the right song.
