I can not hear my own voice when talking on the phone. What can I do?

That’s true of any cell phone. On old landlines the phone internally fed your mic back to your earpiece, a feature known as “sidetone”. But no cell phones do that, because there is a delay of a second or so between your voice and what the person on the other end hears, and if that got fed back to you it would be too confusing as you would hear whatever you said a second later.

I can't hear myself talking on the phone when my AirPods are on. I have the gen 3 AirPods. the earlier AirPods i can hear myself talk. any ideas?
