6. Troubleshooting
| Problem | Possible Solution |
|---|---|
| No audio from headset | Check if the 3.5mm jack is fully inserted. Ensure the headset is selected as the default audio output device in your computer's sound settings. Check the volume levels on both the in-line control and your device. Ensure the speaker mute button is not active. |
| Microphone not working | Ensure the microphone mute button on the in-line control is not active. Check if the headset is selected as the default input device in your computer's sound settings. Ensure the microphone is positioned correctly. If using the Y-adapter, ensure it is correctly connected to both mic and audio ports. |
| Poor audio quality / Static | Ensure the 3.5mm jack is clean and fully inserted. Try connecting the headset to a different port or device to rule out device-specific issues. Avoid placing the cable near sources of electromagnetic interference. |
