Yes, I've heard some variation between pairs. I guess I'm lucky to have gotten an agreeable pair.
I hope your second pair fits you well - I really enjoy mine.
And what are the cosmetic issues? There was a known problem with the headband a couple years ago, but I haven't heard of anything else.
The headband is marred up on the left side (plastic part). It's not really scratched, the best way I can describe it is that it looks like if you were to constantly rub two of those pieces together it would take away the matte finish and make it shiny. It would be fine if it was uniform but this is in a funny looking zig zag pattern that is pretty noticeable up close. Other than that, if I decide to keep these I will send out for the Sennheiser freq response graph so I can see what makes these so smooth.
