..... like I said ..... preference (although I personally wouldn't call the K612 veiled in the mids in the slightest)
K702 definitely has a little more resolution - but it's not on a different planet (at least to my ears).
As far as 'break-in' goes, I'll leave that to the individual. Tyll's tests on the Q701 didn't indicate night and day changes - and I'd never noticed major changes with my K701, K702 or Q701.
You bet! I also think that we may be used to different source material.
I don't know yet; just got them a few days ago. They were unlistenable to my ears straight out of the box, better after 3 days of burnin, but still sound like they have a way to go. FWIW, after 30+ of audio, I only became a believer in burnin after buying the 702. I always thought that it was me who brokein, but the sonic changes in the 702 were undeniable, IME. The 612 wasn't nearly as sensitive to the phenomenon, for a lack of a better descriptor.
