How to Make Your Windows PC Use “Mono” Audio (So You Can Wear One Earbud)

Last Updated: Feb 10, 2024 by

If you’re someone who likes to listen to music or podcasts while working on your computer, you may have encountered the issue of only being able to hear audio through one earbud. This can be frustrating and uncomfortable, especially if you’re wearing headphones for an extended period of time.

Fortunately, there is a solution to this problem – using “mono” audio. In this article, we’ll explain what mono audio is, why it’s useful, and how you can make your Windows PC use it.

What is Mono Audio?

Understanding Stereo vs. Mono Audio

Before we dive into how to make your Windows PC use mono audio, it’s important to understand the difference between stereo and mono audio.

Stereo audio is the standard for most audio devices, including headphones and speakers. It uses two channels of audio – left and right – to create a sense of depth and direction in the sound. This is why you can hear different instruments or sounds coming from different directions when listening to music or watching a movie.

On the other hand, mono audio uses a single channel of audio, meaning that the same sound is played through both the left and right channels. This results in a more “flat” sound, without any sense of direction or depth.

Why Use Mono Audio?

So why would anyone want to use mono audio instead of stereo? There are a few reasons why someone might prefer mono audio:

  • Hearing Impairment: For individuals with hearing impairments, mono audio can make it easier to hear all the sounds in a piece of audio. This is because stereo audio can sometimes make it difficult to distinguish between sounds coming from different directions.
  • Wearing One Earbud: If you’re someone who likes to wear one earbud while working or doing other tasks, using mono audio ensures that you can hear all the audio in the piece without missing anything.
  • Audio Mixing: For audio professionals, using mono audio can make it easier to mix and edit audio tracks. This is because mono audio eliminates the spatial effects of stereo audio, allowing for a more accurate representation of the sound.

How to Make Your Windows PC Use Mono Audio

Now that you understand what mono audio is and why it can be useful, let’s dive into how you can make your Windows PC use it.

Method 1: Using the “Mono” Audio Setting

The easiest way to make your Windows PC use mono audio is by using the built-in “Mono” audio setting. Here’s how to do it:

  1. Right-click on the speaker icon in your taskbar and select “Open Sound settings.”
  2. In the Sound settings, click on the “Sound Control Panel” link on the right-hand side.
  3. In the Sound Control Panel, click on the “Playback” tab.
  4. Right-click on your default audio device and select “Properties.”
  5. In the Properties window, click on the “Enhancements” tab.
  6. Check the box next to “Mono” and click “Apply.”
  7. Click “OK” to save the changes.

Your Windows PC will now use mono audio, meaning that all audio will be played through both the left and right channels.

Method 2: Using a Stereo to Mono Audio Adapter

If you’re using headphones or speakers that don’t have a built-in “Mono” setting, you can use a stereo to mono audio adapter to achieve the same effect.

These adapters are small devices that plug into your audio jack and convert stereo audio to mono. They are relatively inexpensive and can be found at most electronics stores or online.

To use a stereo to mono audio adapter, simply plug it into your audio jack and then plug your headphones or speakers into the adapter. Your Windows PC will now use mono audio.

Method 3: Using a Mono Audio Jack 1/4″

If you’re using professional audio equipment, you may have a mono audio jack 1/4″ on your device. This is a larger version of the standard audio jack and is commonly used in recording studios and live performances.

To use a mono audio jack 1/4″, simply plug your headphones or speakers into the jack. Your Windows PC will automatically use mono audio.

Troubleshooting Mono Audio Issues

If you’re having trouble getting your Windows PC to use mono audio, here are a few troubleshooting tips:

  • Check Your Audio Settings: Make sure that the “Mono” setting is enabled in your audio device’s properties.
  • Try a Different Audio Device: If you’re using a stereo to mono audio adapter, try using a different one to see if that resolves the issue.
  • Update Your Audio Drivers: Make sure that your audio drivers are up to date. You can do this by going to the Device Manager, expanding the “Sound, video and game controllers” section, right-clicking on your audio device, and selecting “Update driver.”
  • Restart Your PC: Sometimes, a simple restart can resolve audio issues.


Using mono audio on your Windows PC can be a useful solution for those who have hearing impairments, like to wear one earbud, or work with audio professionally. By following the methods outlined in this article, you can easily make your Windows PC use mono audio.

If you encounter any issues, try troubleshooting using the tips provided. With mono audio, you can enjoy your audio content without any discomfort or frustration.
