Koss SB40 Computer Headset with Microphone, black/gold

PRODUCT DESCRIPTION With a dynamic element that delivers premium sound at all volume levels, the KOSS SB40 Full-Size Communication Headsets are ideal for gamers who crave deep, sound bass. Equipped with a noise-cancelling microphone that eliminates excessive background noise for greater ease of use, it’s the one headset every gamer should have in their arsenal. Large, closed, leatherette earcups surround the ear for maximum isolation and increased comfort, and also offer high noise sensitivity and reduced sound distortion. The SB40’s sound is so efficient, you’ll hear your opponents before they even know you're there. Designed to withstand the rigors of daily wear, this Koss gaming headset fits like new even after years of kicking butt and saving the world. Like the SB45, the SB40 will bring your games to life. AMAZON.COM Enjoy quality sound and hands-free talking at your computer with the SB40 computer headset from Koss. The closed-ear headphone, or stereophone, as Koss calls it, blocks sounds from within the earcups and without, maximizing privacy and intelligibility. The boom microphone offers a pickup pattern that rejects off-axis sound, so the parties on the receiving end of your calls will hear your voice and little else from your mic. Smooth leatherette cushions and the headband's adjustable, cloth sling and provide comfort during extended use, while the headset's straight, 9-foot cord grants ease of movement at a good-sized radius from your work station.What's in the BoxHeadphones, data sheet.
