Before You Begin:

• Make sure your Bluetooth microphone is turned on and paired with your computer.

• Confirm it’s connected via Bluetooth. You can check this under Settings > Bluetooth & devices.

Step-by-Step Instructions:

Step 1: Open Sound Settings

Click the Start button or press the Windows key.

Type “Sound settings” and press Enter.

• You can also go to:

Settings > System > Sound

Step 2: Set the Bluetooth Mic as Default

Scroll down to the Input section.

Under “Choose a device for speaking or recording”, click the dropdown menu.

Select your Bluetooth microphone from the list (e.g., “Headset (Your Device Name)”).

Tip: If you don’t see your device listed, click “Add device” under Bluetooth settings to reconnect it.

Step 3: Test the Microphone

Under the same Input section, you’ll see a Test your microphone bar.

Speak into your Bluetooth mic — if the bar moves, it’s working!

Optional: Set it as the Default in the Control Panel (for advanced apps)

Some programs (like Zoom or voice dictation software) might rely on the Windows Control Panel defaults.

Here’s how:

Open Control Panel → click Hardware and Sound → then Sound.

Go to the Recording tab.

Right-click your Bluetooth mic and select Set as Default Device and/or Set as Default Communication Device.

Click OK to apply changes.

Troubleshooting Tips:

• If your mic isn’t working, try disconnecting and reconnecting the Bluetooth device.

• Ensure the device isn’t muted and has adequate battery.

• Restart your computer if changes don’t take effect.

Still Not Working?

If you’re still having issues, check your microphone privacy settings:

• Go to Settings > Privacy & Security > Microphone

• Make sure Microphone access and Let apps access your microphone are turned On
