Hello, omerati,
Thanks for using Apple Support Communities, it's great to have you here.
We want to help you get your AirPods Pro working at their best, especially Active Noise Cancellation and Transparency mode are concerned. To start, have you tried resetting your AirPods to see if that may help? Whenever we're seeing this type of unexpected behavior, a reset is usually a good first step and can often resolve the issue in and of itself. This article has more information: How to reset your AirPods and AirPods Pro - Apple Support
Once you have completed those steps, go ahead and test the AirPods out again and see if you have better luck.
If you’re still hearing the static after resetting your AirPods Pro, we recommend seeing if your set qualifies for this Apple Repair Program: AirPods Pro Service Program for Sound Issues - Apple Support
We hope this does the trick for you!
Cheers.
