First International Digital has just introduced the iRock! 5.1 Theater Sound USB Headphones that operate, you guessed it, via USB. These look to be a serious pair of headphones — each sound chamber is packed with six speakers! This means it's able to capture a virtual surround sound experience, complete with 3D sound configuration, for movie watching and PC gaming. And because it uses USB, no sound card is required, which is great for those with sub-standard sound cards but still want high-quality audio. Available now at iRock's website for $49.99.
