Your original question was how do the Kz As10s compare to a couple of open back full sized cans which even you admitted was not a reasonable comparison. I merely tried to provide a comparison of things with some similarities to the cans you ask about.
I think most people have expectations based on price point so It is reasonable to use that as a basis. The ESR is designed to be a studio reference as is the HD800s so they do share similar sound quality and level of details if with differing signatures. The b400 has gotten to be one of the best value picks for iems in much the same manner that the HD6xx has in over-ears so, again, some basis for the use of the two.
You can choose to compare and contrast anything you like, but relevance is lost when you go too far with it.
As far as expecting comparisons that don't involve price, it can be done, but most often you get no more than you pay for although sometimes you get a lot less. As I have said before, even in fairy tales, giants are rare and giant killers are the stuff of legend. If you are lucky, there might be one in your lifetime, not the one every other week that has become the expectation with some people.
What are your thoughts about this?
P.S. Do check the flair.
