How to Use Bluetooth Microphone in OBS Studio

Using a Bluetooth headset microphone with OBS Studio can sometimes be tricky due to how operating systems handle wireless audio profiles. This guide provides a straightforward, step-by-step walkthrough to configure your computer’s audio settings and OBS Studio properties so you can reliably capture clear voice audio from your wireless headset during streams or recordings.

Step 1: Connect Your Bluetooth Headset to Your Computer

Before launching OBS Studio, ensure your Bluetooth headset is paired, connected, and active on your computer.

• On Windows: Go to Settings > Devices > Bluetooth & other devices and confirm your headset is connected.
• On Mac: Go to System Settings > Bluetooth and ensure your headset is active.

Step 2: Set the Correct Audio Profile (Windows)

Bluetooth devices on Windows typically use two different profiles: Stereo (high-quality audio, output only) and Hands-Free AG Audio (lower-quality audio, output + microphone input).

To use the microphone, Windows must activate the Hands-Free profile. 1. Right-click the Speaker icon in your Windows system tray and select Sound settings (or Sounds on older versions). 2. Go to the Input section and ensure your Bluetooth headset’s “Hands-Free” option is selected as your default input device.

(Note: When the microphone is active, your headset’s headphone audio quality may temporarily drop to mono/low-bandwidth due to Bluetooth limitations.)

Step 3: Add the Bluetooth Microphone in OBS Studio

There are two ways to add your Bluetooth microphone to OBS Studio: as a Global Audio Device or as an individual Source. Using an individual Source is recommended for better control.

Method A: Add as an Audio Input Capture Source (Recommended)

1. Open OBS Studio.
2. Go to the Sources dock at the bottom of the screen.
3. Click the + (plus) icon and select Audio Input Capture.
4. Name the source (e.g., “Bluetooth Headset Mic”) and click OK.
5. In the Device dropdown menu, select your Bluetooth headset microphone (look for “Hands-Free” or your device’s name).
6. Click OK.

Method B: Add as a Global Audio Device

1. In OBS Studio, click Settings (located in the bottom-right Controls dock).
2. Click on the Audio tab in the left sidebar.
3. Under the Global Audio Devices section, find Mic/Auxiliary Audio.
4. Click the dropdown menu next to it and select your Bluetooth headset microphone.
5. Click Apply and then OK.

Step 4: Verify and Monitor Your Audio

Once added, look at the Audio Mixer dock in OBS Studio. Speak into your headset microphone; you should see the green, yellow, and red volume bar moving in response to your voice.

If the bar does not move: * Verify that your headset is not physically muted. * Go back to your computer’s system sound settings to ensure the microphone input volume is turned up. * Restart OBS Studio to allow the software to refresh its connection to your Bluetooth hardware.
