How to use
Connect the USB-C plug to a compatible device that accepts USB-C audio. Adjust the head-band for a secure but comfortable fit so the ear cups sit directly on the ears. Position the microphone (if present on the cord) close to the mouth for best voice pickup and avoid obstructing it with clothing. Use device settings or communication software to select the USB-C audio device as the input and output source and adjust volume levels as needed.
Usage recommendations
For consistent call quality, keep the cable untangled and avoid sharp bends near the connectors. When using the headset for extended periods, take short breaks to relieve pressure on the ears. If your device has power management settings, disable any features that may reduce USB peripheral performance during calls.
