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 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.
Along with the perfect fit, the SB42 USB headphones deliver 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.
