Using Siri or the iPhone volume controls, it is possible to change the volume of the audio content being played through the AirPods Pro. However, so far I have not found a way to change the volume of the notification sounds that are being played when I receive a message, when I switch to Transparency mode and back, etc.
I tried to call up Siri and change the volume while Siri is on screen, but this didn't work.
These noises are incredibly loud, and I really would like to reduce their volume. Is this possible?
