- Open the Start Menu and search for Sound Settings.
- Click on the first result, scroll down and click on More sound settings. This will bring up a popup with further controls.
- Click on the Recording tab, select the Onikuma Headset’s microphone and click on Set Default.
- Click on OK and this should fix your Onikuma headset mic not working issue.
Fix 2. Check Privacy Settings
Windows has an in-built privacy manager that allows you to restrict certain apps from accessing your webcam, speakers, or microphone. If none of the apps or games on your computer have been able to pick up your audio using your headphones, there’s a good chance that the privacy setting for the microphone is restricting access.

- Open the Settings app and click on Privacy & security on the tab to the left.
- Scroll down until you find the Microphone option under the App permissions section.
- Click on it and ensure the Microphone access toggle is enabled. Furthermore, check to see if any apps you use or games you play are being denied access to your microphone in particular and enable it.
Fix 3. Run the Audio Troubleshooter

Windows also offers a troubleshooter for virtually any error that you might run into, be it compatibility issues with certain apps, or network troubles. You can run a troubleshooter specifically for your microphone and let Windows automatically look for any problems and fix them.
- Open the Start Menu and search for Troubleshoot settings and click on the top result.
- From the Settings menu that shows up, navigate to Other troubleshooters and click on the Run button next to the Recording audio option.
- A troubleshooter window should now pop up. Select the microphone that’s connected to your Onikuma headphones and proceed with the troubleshooting process. Windows should identify and rectify the issue.
Fix 4. Update the Audio Driver

Traditionally, Windows should automatically detect new hardware and install the appropriate drivers for your headphones and their microphone, but it sure doesn’t hurt to ensure you’re on the latest driver. Onikuma doesn’t provide any specific audio drivers for their products, so the next best thing you could do is open up Device Manager on your computer and check for any driver updates for your headphones. Alternatively, you should be able to install new drivers in the Windows Update options.
If all else fails and you’re suspicious of a hardware-level defect with your headphones, it’s time to contact support and file for a service or replacement. Fortunately, Onikuma has great support and offers a 30-day refund policy and a 1-year warranty for products purchased through their website. You can contact Onikuma support to see if they’re willing to fix or replace your headphones.
