The Beats by Dr. Dre Studio - High-Definition Isolation Headphones (White) combine extra-large drivers and a high-power digital amplifier. Powered by a pair of standard AAA batteries, these Around-Ear, closed-back, foldable headphones are equipped with active noise-isolation technology to help reduce ambient noise from trains, planes and other sources. Plush, Around-Ear cushions provide additional noise isolation as well as comfort.
The headphones come complete with two detachable cables, one of which has an inline mic/remote-control module for use with an iPhone or other smartphones compatible with Monster's ControlTalk Universal standard. The cables are designed to reduce signal loss for improved balance and clarity. They feature gold-plated 1/8" (3.5mm) TRS stereo mini plugs, allowing you to use the headphones with a huge variety of MP3 players, CD players, computers and other devices.
Another useful feature is the Mute button, located on the outside surface of the Studio's right ear, which lets you mute the headphones without taking them off.
