For Microsoft Windows users, the "Volume Mixer" allows you to set volume settings for individual speakers or headphones. Right-clicking the volume icon or searching "Adjust System Volume" in the Windows Control Panel will open the window to change your sound settings. To find the sound settings on a Mac, click the apple icon in the top left corner of the desktop, and open System Preferences to locate the Sound menu. From there, a list of output options will show you the volume levels of the connected device you're using.
