Airpod Pro static noise in left earpiece.

Hi Sweet640,

If you'd like your AirPods to sound great no matter what mode they are in, these steps might help. 

Follow these steps.

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

2. Check that your connected device is nearby, and there's no wireless interference or obstructions between you and your device. 

3. 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.

The information above is from If your AirPods Pro make crackling or static sounds. Note: Only AirPods Pro manufactured October 2020 are part of the program linked above. No other AirPods models are part of this program. If the issue continues, let us know what steps you had a chance to try from above and what you found for each test.

We hope that helps with your question and take care!
