The main point was to make you see that there is a world outside of manuals. Sometimes you find something that works for you that is not exactly as written in the manual - be it seating position, speaker volume, screen brightness, etc.
We are not all the same and I doubt aircraft manufacturer (be it Boeing, Airbus or anyody else) can come up with - in this case - a speaker volume settings that works for everybody and for all possible situations.
Personally, I normally use headset only on one ear, so speaker volume is set to somewhat mid-range. If I use it on both ear, I turn it off completely and if I don't use headset, I increase the speaker volume.
Again, it's not rocket science. Just try some different settings and see with which setting you feel most comfortable.
