AirPods not working with my iPhone 11

Why don’t my AirPods work with my iPhone 11?

I have tried restarting, repairing, taking off the cover and turning off cellular data and WiFi calling. I bought another pair of off brand ear buds and they won’t work either. My AirPods work fine with my iPad and with my old iPhone 6. I did get a small wireless speaker to work with my iPhone so why won’t the AirPods work?!
