When I use my airpod pro while walking fast, I can’t make a phone call because my correspondent can’t hear me properly

Hi MickaelKwasnik,

For help with calls when using your AirPods while outdoors, test the steps below for enabling Active Noise Cancellation found in the article here: AirPods Pro and AirPods Max Active Noise Cancellation and Transparency mode - Apple Support

"Switch between noise-control modes on your iPhone or iPad

1. Open Control Center on your iOS or iPadOSdevice.
2. While wearing your AirPods Max or both AirPods, touch and hold the volume slider until you see the additional controls.
3. Tap the Noise Control icon  in the lower-left corner.
4. Tap Noise Cancellation, Transparency, or Off."
