Recommendations

For best microphone performance, position the Environmental Noise Cancelling microphone close to the mouth but not directly in front of the airflow. Keep the QD connection secure and avoid sharp bends in the cable. Use the headset within the specified temperature and humidity ranges for reliable operation.
