After 25 years, Dr. Dre was tired of spending months on a track only to have his fans hear it on weak, distorting earbuds. Two years & hundreds of prototypes later, Beats Studio headphones are the icons that bring you sound the way it was originally intended. Powered by a pair of AAA batteries, the noise cancellation feature in a pair of Beats Studio headphones amplifies the music as it blocks out noise, giving you consistently powerful & intense sound Super plush & covered with ultra-soft breathable materials, you’ll be cool & 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 headphone that always delivers a comfortable fit. The result is a design now copied by brands around the world. Take calls, skip songs & adjust volume right from the cord of your Beats Studio headphones. No more searching for your phone or music player just to find the right song.
