Different FR, different distortion characteristics, different driver types even. A 2-way balanced armatures in-ear will be very different from an open circumaural in presentation as well. In headphones, full sized ones anyway, you can build a driver to cover the full spectrum of sound, while this is totally impossible for any single driver in a speaker.
The decrease in harmonic distortion with increasing SPL seemed odd; the distortion comparison between the Headroom measurements and Innerfidelity isn't quite consistent.  For certain headphones (e.g. the LCD-3) the decrease in THD+N with increasing SPL corresponds almost exactly to the increase in volume. We might conclude Tyll's system has a fairly high noise floor from that, but his measurements for Headroom show much lower harmonic products for each headphone and a much...
This is damn useful, for the knowledge and as a point of research. Thanks for the chart.
Bit depth, method (VBR, two-pass, etc.) will matter here. Some iteration of the codec are better than others.
A recently disgraced Nigerian nobleman recently contacted me to advance him an HD600 so he could use it to flee the country. For my trouble I will recieve two pairs of the Orpheus. I'm so excited!!

Huh? That is to do with the rig tolerance for positioning. Never mind the fact that two headphones of the same make can sound different.
Product variance is always a factor here, and Beyer isn't the most stringent company with its control. Looking at a headroom graph of four DT880s:     We can't dismiss pad condition as factor either for sonics.
Where did you hear that the Beyers are bass-lite? Both of those headphones have boosted midbass. I would go so far as to say that the DT880/600 is just a 650 with a peak in the low treble, which may be the culprit here for varying impressions.   It could be that the drivers themselves have been jostled out of place and are not creating the usual amount of bass for the headphone. What I really think is that the 650 just isn't as slow, thick and bloated as you might hear...
