Quest 3 External Audio Setup

Brendan Scott /

We see a lot of requests regarding external audio setup for VR. This guide covers how to enable and set up an external mic on the Quest 3.

Don't settle for a gaming headset! Discover how ModMic changes the game.

Some notes before we get started:

  • This tutorial is for setting up either the ModMic Wireless or ModMic USB 2 as an external mic via the USB-C port on the Quest 3.
  • The 3.5mm input on the headset is an audio output for headphones, and this does not support a 3.5mm microphone input, like the ModMic Uni 2.
  • You must use A USB C to USB A adapter for the ModMic Wireless dongle and the ModMic USB 2 to connect to the Quest 3.

Although the USB 2 comes with an adapter, SixTacos (video guide at the bottom) suggested this as an alternative: The BCLINK 2-in-1 USB C to USB 3.1 adapter. This allows the user to seamlessly integrate the devices so they are parallel with the headset, and out of the way of potential physical mishaps. This particular adapter also allows you to use an external microphone while charging simultaneously.  

Now that we've explained the technicalities, let's get to the actual setup portion!

Step 1

First off, you have to make sure that your software is up to date to be able to utilize the external microphone settings. Go to the "General" section of the Quest settings, and make sure that "Software Updates" is toggled to on, and that the top of the screen indicates "You're all up to date!" v74.1020 is the current version (as of 4/3/25) that allows this to function, although some earlier versions are supported. This step is shown in the picture below.

Step 2

After updates, the next step is to enable external microphone capabilities. Go to "Advanced" settings and turn on the "External Microphone" toggle. You must then restart the Quest headset for the changes to take place, shown in the following photo.

And voilà, setup is done, and you are ready to use your ModMic with the Quest 3!

Here is a video from a SixTacos regarding the setup process with the ModMic Wireless. Keep in mind, the video is over 9 months old, so the software update referred to in the video is a bit outdated.
