Unclear robotic voice on iPhone 13 Max Pro phone call

So I posted already about experiencing the same issues as everyone else. But I want to give an update because I found the problem for my phone. I have an iPhone 11 Pro Max on Verizon. What I noticed was that the problem wasn’t happening when I was on my car speaker phone or simply talking on speaker. It was only happening when I had my AirPod Pros connected. So once I realized that, I have given it a few tests to ensure that that was the issue. And sure enough if I am not connected to my AirPod pros than the distortion and breaking up does not happen. So now I realize that the problem is not the phone but the AirPod Pros when they are connected. Still annoying, because the AirPod pros work fine listening to music but for some reason they distort every phone conversation. Sounding as if there’s interference or as if I have a bad signal. So it’s very weird. These are my third AirPod pros because something has always been wrong with them. So I’m assuming Apple sent me a refurbished pair and that may be the issue. But everyone in my family who uses regular AirPods do not have this problem. Hope this helps someone maybe narrow down the issue.
