I would say that to me the substitute of the MMk2 would be the hd600 but with everything scaled down in quality and worse bass. But the midrange/vocal fullness is similar.Sorry for the off-top, which headphones sound similar to the Mk3 or Mk2? I am looking for what you just described but with the combination of good bass and gorgeous detailed mids at the same time. And I am completely incompetent in headphones, I just know I don't like the bass of Sennheiser HD 800.
