"...block ambient noise so you can hear every note without blowing out your eardrums."

"Turtle Beach's ANR-10 headphones. . . fit behind your neck, with foam pads that rest comfortably on your ears, and they have built-in active noise reduction to filter out background interference, like your boss's voice."

"One cool thing about the headphones is the placement of the noise reduction circuitry and batteries which are inside the headphones and therefore eliminates the usage of a control box."

"...it's when you power up the noise cancellation features with a single AAA battery that you'll really hear the difference."
