I didn't come to think of the equal loudness curve, good point there. Still I'd like to point out that the frequency reproduction of a headphone is constant independent of the volume it's playing at, while the ears' sensitivity to different frequencies is variable at different volumes, as the Fletcher-Munson curve shows. Thus, the headphone itself isn't capable of correcting the level of the music signal according to the equal loudness curve, but this must be done with...

I must say the information you provided was indeed...
