I am very new on the forums, actually this is my 2nd post of all time. I apologies in advance for my English, since it is not my first language.
So well, here goes nothing - I got the HD 800's and not even a month has passed that I got something like a smudge on the membrane (?) - shown with the red circles on the picture below.
Someone who I know told me to use soft brush and one of those compressed air cans to try and clean it, but it does not seem to work. The Canadian Sennheiser Customer Support centre only has a voice mail box, at don't seem to call you back (waited for 2 weeks so far).
The store I got it from - Bay Bloor Radio, has no idea how or what it is and how to clean it.
So I am a bit freaking out right now, it's not the cheapest pair of headphones out there.
Anyone had any experience with such things? Any comments would be more than useful, tried searching but don't seem to get any results.
