I prefer the midrange of k501 to k701. It is a bit more relaxed. Anyway, the midrange of k701 is very nice indeed and easy to live with. I don't really understand the "plasticity" comments comming from some people. But, doesn't every headphone have a "tag" attached to it? k70x are plasticky, HD6x0 are veiled etc. I cannot hear any of it.
