## Long description

The Koss SB40 wired headset provides a full-range sound experience with a frequency response of 20–20,000 Hz and a dynamic driver tuned for pronounced bass. Designed for calls, music and gaming, the SB40 combines closed, circumaural ear cups and leatherette cushions for passive noise isolation and extended comfort.

Soft leatherette ear cushions reduce pressure for long wearing sessions, and the adjustable headband ensures a secure fit for most head sizes. The microphone suppresses excessive background noise, improving clarity for PC voice applications and calls. Wired connectivity provides reliable signal transmission without the need for batteries.

How to use
Connect the wired headset to the appropriate audio input on your computer, console or device. Position the adjustable headband so the ear cups fully surround your ears and the microphone is near your mouth but not touching it. Adjust playback volume from your device and, if available, within the application you are using. For voice applications, speak normally and test the microphone level to ensure clear capture while reducing background sounds.
Usage recommendations
For best results, use the SB40 in quiet or moderately noisy environments to take advantage of the closed ear cups' passive isolation. Store the headset in a dry place and avoid excessive pulling on the cable. If using for long sessions, periodically adjust the headband and ear cushions to maintain comfort.
