Kind of disagree about Q701 similarity, however not vs. K702, but vs. K701, but again, man says K702 are simply K701 with differ color and detachable cable, so, if that's the true, I must say, extremely is to extreme in my book, cos Q701 have clearly added warmth in the sig that I can't really explain yet, while K701 are simply better in the sense of refinement, clarity and preciseness, they sound simply right and Q having some kind of mixture in sig, which make them bit fun or something like that. My Q pair have around 170 hours and they open up nicely, not really miles ahead from new, but still going good and if I have to believe that K7.. models need around 400-500 hours to perform at full potential, I guess my Q still have a long way to go.
I also expecting K702 shortly, would be interesting to find out how they compare to K701 and Q701. Will be getting some custom made cables for them as well.
