ViviTouch 4D Sound transforms your headphone listening experience into a whole new sensory dimension of audio that sounds as if it's alive. It changes how you hear, not what you hear, producing rich, full-bodied sound that you can actually feel — just like you were experiencing it live. Listening to recorded music catapults you straight to the front row, movies become full-on cinematic events, and gameplay engulfs you in an utterly lifelike world. Whenever you want to be there live, all you have to do is plug in (USB mode only).

Employing the highest quality drivers available for use in commercial headsets – neodymium – the F. R.E. Q.4D Stereo Headset feeds high-fidelity audio through a pair of precision-balanced 50mm speakers for deep bass and crisp, undistorted highs. The skillfully engineered earcup design also helps block out distractions like excessive teammate chatter so you can focus on gaming at your best.

An earcup-integrated mic gives you the freedom to chat with your teammates without the distraction of a fully extended microphone in your periphery. And when privacy is a concern, simply tap the mute button to prevent your teammates from hearing anything you don't want them to.

Use the headset's handy quick-release connector to instantly gain MP3 player compatibility and convert the Mad Catz F. R. E. Q. 4D into portable headphones. Just swap out its USB cord for the included 3.5mm audio cable – replete with in-line controls for media and phone calls – and then plug directly into your device. And if you have a smartphone*, you can even take voice calls using the integrated microphone. (*Supports Apple iPhone, Samsung, BlackBerry, and HTC handsets. )
