The Koss CS300 USB is a double-sided on-ear communication headset for office phones, conferencing and other professional calling tasks. Both ears are covered, which helps when the workplace around the user is busy.
Key specs that matter
The earcups reproduce 20 Hz to 22,000 Hz. The flexible arm carries a noise canceling electret microphone, and the 2.4 m cord terminates in a USB connector.
Engineering and use context
Soft, pillow-like cushions sit on form fitting Koss D-Profile earcups, and the lightweight build targets all-day wear. The USB connection lets the headset plug straight into a computer with no separate analogue jack. Koss includes a Limited Lifetime Warranty with it.
