Is that the sort of "scratch" or "crunch" I hear from my Sennheiser HD 4.50's or is it something else?

At first, I didn't even notice it, but now I went back to listen more carefully. I'm not sure if my headphones are "quality" or not but they are the most expensive set I've ever owned.

I hear no clipping (like sudden silence) at the end of notes, even if I wait a long time. But, my ears are not tuned.
