The SB45 Multimedia Headset from Koss delivers a full range of sound that enables you hear and speak clearly. Featuring Clear Voice Technology (CVT), its noise-reducing microphone is designed to cut down on background noise. This makes PC voice applications, such as speech recognition, easier to use. With soft, leatherette ear cushions, you can wear the headset comfortably over an extended period. The large, closed earcups maximize isolation so you can focus on the task or conversation at hand. This multimedia computer headset easily folds up for compact storage or transportation.
