Koss CS100 USB headset for PC communication

The Koss CS100 is a supra-aural headset with a USB connector designed for hands-free PC communication. Its electret noise-cancelling microphone targets clear voice capture for calls, speech recognition and multiplayer gaming. The lightweight 0.45 kg build suits extended sessions at a desk. Buyers needing wireless freedom or audiophile-grade music reproduction should look elsewhere.

Thermals noise and power over USB

The headset draws power directly from the USB port so no external adapter or battery is required. Passive cooling keeps the ear cups at ambient temperature during normal use. The inline cable carries only low-voltage digital audio, producing no audible coil whine or fan noise. Users who need hardware mute switches or dedicated DSP controls will not find them here.

USB plug and microphone benefits

The single USB plug provides driver-free audio and microphone connectivity on modern operating systems. The electret microphone reduces background noise for clearer voice transmission in conferencing apps. Supra-aural pads rest on the ears rather than enclosing them, which helps heat dissipate during long calls. No carry case, spare pads or software suite are included in the package.

Questions about this item

How do I install the CS100 USB headset on my PC?

Insert the USB plug into any free USB port; Windows will detect the device and install drivers automatically, then select it as the default audio and microphone device in Sound settings.

What part of the CS100 is most likely to need replacement over time?

The ear cushions on the supra-aural cups wear out first and can be swapped for new pads to restore comfort and seal.

At what volume level does the CS100 start to distort during long calls?

The dynamic element covers 30Hz-16KHz; pushing the system volume near maximum for extended periods can introduce audible distortion.
