The Koss CS100 communication headsets boast a full range of sound that helps bring every conversation to life. With high noise sensitivity and reduced sound distortion - not to mention hands-free communication via an electret, noise cancelling microphone - it will seem as if the person on the other end of the line is right in front of you.
Whether you employ telephony, voice-activated or voice recognition software - or indulge in computer games with sound cards that feature built-in bias supply - CS100 headsets offer long-lasting comfort to accommodate the longest of telecommunications.Note: Can be used with an external power source if sound card does not have built-in bias supply.
