Koss CS300 USB Headset, Black

The Koss CS300 is a wired communication headset designed for use in office environments, for online calls, or with language learning software. It utilizes an on-ear, double-sided design and connects directly to a computer via a 2.44-meter USB Type-A cable, ensuring a stable connection without the need for batteries or software drivers. The audio drivers cover a frequency response range of 20 to 22,000 Hz, suitable for reproducing clear human speech, which is the primary function of this device.

For vocal input, the headset is equipped with a noise-canceling electret condenser microphone positioned on a flexible boom arm. This feature is intended to isolate the user's voice from ambient background noise for improved clarity during conversations. The microphone arm can be rotated for precise positioning or folded out of the way when not in use. With a total weight of 95 grams and soft on-ear cushions, the headset is built for comfort during extended periods of wear.
