Troubleshooting for the boom mic in the FIFINE H6 headset not working
1️⃣ Insert the boom mic completely into the jack. And make sure to align the boom mic with the tiny slot of the jack.
2️⃣ Check if the mic can be muted by the switch on the in-line controller. The red indicator on means the mic is muted, the red indicator off means the mic is working. If the red indicator is not on after you adjust the mic mute switch, please go back to Step 1 to check if the mic is properly inserted.
3️⃣ After you plug the headset into the PC or laptop, please set it as the default input device in the system sound control panel and software audio settings; otherwise, the mic will not pick up the sound. And disable other mics manually.
4️⃣ Check if the software using the mic allows the use of the mic. Try turning on the Privacy Settings for apps that you want to use with your mic by following the steps below.
Click the “Windows” icon or press “Win” on your keyboard → Click "Settings" → In the pop-up Window, select the "Privacy & security" category → Scroll down and find the "Microphone" option → Make sure the "Microphone access" is enabled.
