I know there's a difference between "harshness" and distortion and I am pretty sure I have been able to make out some other distortion characteristics in the sound-sig. This definitely makes me really appreciate the engineering that went into making the practically perfect distortion measurements for my NAD VISO HP50's (and they are closed cans!).
Perhaps these issues are just with my pair of cans but I am probably going to try a different manufacturer after these issues. It's a shame really... the K712's did a LOT right sound-wise and were very comfortable. Planned on making them a permanent fixture for my set up, but alas it was not meant to be. Everything that takes place, for good or for naught, adds to your experience though, so with that in mind I am glad that I was able to own these headphones if only for a few brief moments.
I actually had a weird experience with my K612, in the first few weeks I had them, I noticed distortion when heavy bass played, I took off the pads while the distorted bass was happening, I noticed the drivers were crinkling when playing heavy bass, interestingly this crinkling driver problem went away with time and I can't distort them anymore. My K712 had no such problems. Given the similar design of the headphones and identical looking drivers and driver enclosures between the two headphones, I wonder if this is something that happens with some AKGs. I've also heard of this problem before.

If you were nearby I'd wonder if you felt the SQ was the same on my unit, because the AKG's are the most immediately attractive in their price range that I've heard (I haven't heard a Sennheiser HD650/HD600 yet, though FWIR your brain has to adjust to the sound signature of those before you appreciate them, that's what is happening for me and the DT880). I wish you luck, hope you find something awesome
That is true, headphones do take some time to adjust to. Setting aside sometime for a headphone helps one become used to it. It can yield interesting results when swapping from one headphone to another especially after using a pair for a while. It took some listening and swapping around headphones every few days and the like to realize my K712 is without a doubt my best headphones, at first I wasn't sure if they were. I took listening to all my headphones a fair amount in a rotation to realize this. I also realized the K712 is in a league above my second best headphone the K612 sonically.
I really like all three of my full-size headphones, first time I had this many headphones I really enjoy. It used to be there was just one headphone I liked and the others were ignored, but with the K712, K612, and HD 545. I can easily switch between them and appreciate each of them and not feel wanting. Now I just need to get a beefier amp to help bring out the potential of the headphones more.
