Sony WH-1000XM3 or XM4 is one of the best noise cancelling headphones. But the mic not working issue can make users out of ideas as to what to try. If you’re encountering the same issue, the methods listed in this article may help you fix it.

Before getting started

Before moving to the advanced fixes, you need to isolate the problem. You should check if the headphones work on other devices. Simply connect headphones to a different device and check if they are working. If not, the problem lies in the headphones’ end and you should contact the customer service or may consider investing in new headphones.

If your headphones work perfectly in other devices, try these fixes:

  1. Make sure your microphone is enabled and set as the default device
  2. Unmute your microphone
  3. Update your audio driver
  4. Try Windows 10 Troubleshooter

Fix 1: Make sure your microphone is enabled and set as the default device

Normally, when your microphone is connected, Windows can automatically detect it and set it as the default input device. But sometimes it just fails to do that and you have to set it manually. Also there may be a possibility that it’s disabled. To troubleshoot the issue, you can take these steps:

1) Right-click the volume icon in System Tray at the right end of the task bar. Then select Open Sound settings.

2) Under the section of Input, click the drop-down and select your headphones from the list.

6) Under the tab Recording, select your microphone and click Set Default > OK.

After you’ve done these, test if you can get the microphone to work. If it’s still not working properly, proceed to the next fix.

Fix 2: Unmute your microphone

Sometimes you may not notice that you actually mute your microphone. To check if that’s your case, take these steps:

1) Right-click the volume icon in System Tray at the right end of the task bar. Then select Open Volume mixer.

2) In the Windows volume controls, a red circle with a slash through it indicate the device is muted. If that’s your case, select your device and adjust the slider to unmute it.

Fix 3: Update your audio driver

The mic on your headphones won’t work if you’re using an incorrect or outdated audio driver. Outdated drivers can become incompatible with an update to Windows, or you may be lacking a new feature required for the microphone to function properly. In this case, you should update your audio driver.

Methods to update your audio driver

To update your audio driver, you can either do it manually via the Device Manager or head to the manufacturer’s driver download page to download and install the exact driver for your system. This requires a certain level of computer knowledge and can be a headache if you aren’t tech-savvy.
