"Heard enough" means that the person has listened to as much as they can bear or is tolerable and doesn't want to listen to anymore or put up with a kind of behavior. It can also be used if someone's listened to a point that they're convinced to do something, but it's kinda used ironically. Ex: I've heard enough about the island, thank you. I'm booking a trip there this afternoon. => convinced Ex: We've heard enough of your complaining, so we're leaving.
