As far as I know, dB calculation goes like this:
dB/mW = dB/mW (headphone) + 10*[log(E^2/R)]
E=Output power of the source as Vrms; (Vp-p/2)*(0.707)
R=impedance of the headphone
In this case, for my X3-II + K612, I can easily calculate my dB range when it comes to high gain and full (120) volume because we know Vrms from the given Vp-p officially. But, how can I calculate if I set the volume to, let's say, 110? Is there a known method for that?
