There is now. I just posted this in the other AirPods thread but in case it helps I am posting it here too —
The latest AirPods Pro firmware update to 4A400 (and maybe needs iOS 15 on phone?) makes the microphone pick up speech directly in front of you (ie not using the Bluetooth connection). I have very variable hearing loss and my hearing currently is about as good as it gets. I find the AirPods alone are as good or better than my current Phonak BTE hearing aids. (Actually because I have the “thin tubes” I can put the AirPods in while wearing the aids so in principle both should be doing something.)
