How to use

Connect the USB‑A plug to an available USB‑A port on your computer. Position the headband for a secure and comfortable fit, and adjust the boom microphone so it sits near the mouth but out of the direct airflow. Use the inline controls to mute the microphone or adjust volume during calls. The headset is recognized automatically by most operating systems; select it as the default audio input and output device in your system or conferencing application settings if necessary.

Recommendations

For optimal voice clarity, place the boom microphone approximately 1–2 cm from the corner of your mouth and avoid covering the microphone with clothing. When using the headset for long periods, take regular short breaks to reduce ear fatigue. Ensure your PC's USB drivers are up to date for best compatibility and plug the headset into a direct USB‑A port rather than an unpowered hub when possible.
