Here's to hoping they're not identical to the K702 65th AE I owned for a bit. But, even then, $200 wouldn't be a bad deal at all from what I remember (I think I paid roughly that?). Even if not as technically competent in all regards, I still preferred the HD598 over the K702 AE. K702 just did some annoying things to my ears, but YMMV since I'm picky and weird. Really looking forward to hearing this particular K7XX iteration!
It's somewhat hard to see any good pictures of the pads, so it's a little hard for me to speculate. I've got a pair of Q701, K702AE, and K712 here, and by the pictures I can get of them, they look like they might be a cosmetic change of the K712 purely based on the pads.
Do you remember what serial number of the K702AE you had?
