AirPods Notifications are EXTREMELY LOUD, while other sounds are not
I tried answering this question on another thread but it was locked from answers, I finally got this fixed!!! See below:
Go to: Settings / Sounds & Haptics / Headphone Safety / turn "Reduce Loud Sounds" ON!!!! / Live a happy life.
80 or 85 decibels have been working great for me so far. Hope this is helpful to everyone!
