Hello LushLitch,
Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with background noise on phone calls using AirPods Pro. Try the steps listed here to see if they resolve the issue using Noise Cancellation: AirPods Pro and AirPods Max Active Noise Cancellation and Transparency mode
"What are Active Noise Cancellation and Transparency mode?
With Active Noise Cancellation, an outward-facing microphone or microphones detect external sounds, which your AirPods Pro (1st or 2nd generation) or AirPods Max then counter with anti-noise, canceling the external sounds before you hear them. An inward-facing microphone listens inside your ear for unwanted internal sounds, which your AirPods Pro or AirPods Max also counter with anti-noise.
Transparency mode lets outside sound in, so you can hear what's going on around you. Active Noise Cancellation and Transparency mode work best when your AirPods Pro fit well.
If you have AirPods Pro (2nd generation) and the latest version of iOS or iPadOS, you can also use Adaptive Transparency to reduce loud sounds around you. While you're wearing your AirPods Pro (2nd generation) and they're connected to your iPhone or iPod touch, go to Settings > [your AirPods], then turn on Adaptive Transparency.
Switch between noise-control modes
You can switch between noise-control modes right from your AirPods Pro or AirPods Max, or you can use your iPhone, iPad, Apple Watch, or Mac. When you switch between modes, you hear a chime.
