With Noise Control, adjust the how much noise is coming through to your earbuds. Toggle between ANC and Transparency Mode to adjust how you hear your surroundings. You can also adjust to what degree the ANC works.
For Microphone, select how loud you want to be heard and whether you want any Sidetone (feedback of your own voice while using the microphone) and to what degree.
Volume Limiter is a safety setting for maximum volume. Certain countries, such as Brazil and those in the European Union, impose legal regulations on safe hearing levels. Disabling or overriding this may result in exposure to sound levels that could cause hearing damage. By doing so, you acknowledge and accept full responsibility for any risks.
If you find that your Arctis GameBuds are quiet, make sure to check the output volumes on the device you're using. For example, set the headset volume on the PlayStation 5 to max, and then simply adjust it via your earbuds. Similarly with PC.
Additional options can be found by pressing onto the cogwheel in the upper right corner of the app. Among them you can find Wear Sense, which automatically pauses audio if the earbuds detect that they are taken out of your ears.
