Creative Labs Fatal1ty Pro Series MKII headset is the ultimate in full on gaming communication. The Pro Series MKII is high-end with ultra-comfortable over-ear memory foam padded earcups for comfort during those extended gaming sessions. Includes inline mute and volume control for your convenience. This headset is ultra-portable with a foldable feature for easy storage and traveling. The proprietary Silencer technology is a noise suppression system that works by using two high-quality microphones in the headset, one on the boom mic and one on the earcup. Noise arrives at different times across the two microphones allowing each noise to create a “noise signature” that is able to be separated from the actual intended voice transmission. Use headset with the Sound Blaster X-Fi Titanium Card to create the full Silencer experience. (Sound Blaster X-Fi Card sold seperately.) Headphones include driver units of 40mm Neodymium Magnet and a frequency response of 20Hz ~ 20kHz. The Microphone includes a Noise-Canceling Condenser (x2), Frequency Response of 80Hz ~ 16kHz, Impedance: <2.2kohms and Interface: 1/8-inch / 3.5mm gold-plated stereo miniplugs with Oxygen- Free Copper (OFC) cable.
