Koss SB42 USB communication headset delivers a full range of sound that enables you to not only hear clearly, but also speak clearly. Featuring Koss’ Clear Voice Technology (CVT), the SB42’s included noise-reduction microphone eliminates excessive background noise. This technology enables PC voice applications, such as speech recognition, to be much easier to use.

The SB42 USB features a detachable cord design with dual-choice entry, allowing the user to choose which earcup to connect to for optimum adaptability. Once the cord is attached, the opposite side becomes an output, allowing pass-through listening or daisy chaining for extended monitoring.

Included with the SB42 USB is an all-new 8-foot cord with integrated boom microphone (with separate audio/voice plugs).

The SB42 USB has the natural fitting, iconic “D-profile” earcup, first featured on the ergonomically designed Koss Pro4AAA and now available on many Koss headphones. The D-profile mimics the shape of the ear, creating an ideal seal for the most consistent sound reproduction. The comfortable design of the Koss SB42 USB will allow you to comfortably wear these headsets over an extended period.

Along with the prefect fit, The SB42 USB headphones delivers great volume, even with low-voltage devices. Closed ear cushions seal comfortably around your ears to block outside noise and keep music from leaking out.

The SB42 USB computer headset easily folds flat for compact storage or transportation.
