well, the thing with k701/702's etc. is, that the bass freq's are a bit... hmm.. tamed, compared to the rest of the spectrum.
But at the same time, if you allow your ear to focus on what you are doing, you can here everything, it's like beeing neo and seeing the matrix for what is it, notching the kickdrum's low from 55 to 56 Hz, changing the q from 0.75 to 0.7, changing the lo-shelf from +1db to +1.5.db. it's an excellent tool
on the other hand, probably all the other high end headphones can do this too... except sennheiser hd series... god I hate those
