Hello mleqYYC,
Thank you for reaching out to Apple Support Communities.
These steps may be able to help:
"If your AirPods Pro (1st generation) make crackling or static sounds
Follow these steps.
- Make sure that you have the latest software on your connected iPhone, iPad, iPod touch, or Mac.
- Check that your connected device is nearby, and there's no wireless interference or obstructions between you and your device.
- Listen to audio from a different app to see if the app causes the issue.
If you still experience sound quality issues—or if the issues increase in loud environments, with exercise, or while talking on the phone—refer to AirPods Pro Service Program for Sound Issues."

They will take a closer look and check on available options.
