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.
