noise cancellation not working on AirPods Pro

Hello eahkee.

Thank you for using Apple Support Communities. We'd like to help you with your AirPods Pro. We notice that you're already coming from the following resource here: If Active Noise Cancellation isn't working as expected on your AirPods Pro - Apple Support

This is the best resource to review for when facing issues with Active Noise Cancellation not properly working. Were you able to follow all the steps listed within that resource?

Make sure that you have the latest software on your connected iPhone, iPad, iPod touch, or Mac.

Put both AirPods Pro in your ears and check that Active Noise Cancellation (ANC) is turned on.

Clean the mesh located on the top of your AirPods Pro. Sometimes Active Noise Cancellation can be affected if debris or earwax builds up in the area shown below. If this happens, you might experience: 

A loss of bass sound

An increase in background sounds, such as street or airplane noise

4.) If Active Noise Cancellation still isn't working as expected, refer to AirPods Pro Service Program for Sound Issues.

We hope these steps help you. Cheers.
