Koss SB42 Headset, Grey

The Koss SB42 is a wired over-ear headset designed for computer-based audio tasks such as voice calls and media consumption. Its closed-back acoustic system provides passive noise isolation by covering the ear to help block ambient sounds. The headset is tuned for a frequency response of 20 Hz to 20,000 Hz, covering the standard range of human hearing. The over-ear design incorporates soft, pressure-sealed ear cushions intended to provide a secure and comfortable fit for extended periods of use.

For voice input, the headset includes a boom microphone designed to capture speech clearly. This microphone is detachable, allowing the SB42 to function as a standard pair of headphones when voice communication is not required. The physical frame is foldable, which makes the unit more compact for storage and transport. A 2.4-meter detachable cable provides ample length for connecting to desktop computers or other devices that are not in immediate proximity, terminating in a standard 3.5 mm connector.
