How to rescale macOS output volume to be quieter

Question

My headphones are too loud for me. How can I resize macOS' volume control so that max volume is only 30% of the actual possible power output?

And then I have fine control within the 0-30% range.

At the moment, 1 pixel from mute is still too loud in some environments.

I don't know a software solution for this on current macOS versions (there are/were solutions up to macOS 10.15; they are likely using kernel extensions and thus don't work on macOS 11+), but you can solve it with hardware:

Search for "headphones volume control adapter". These are adapters you plug in between your Mac and you headphones which can lower the volume.
