Yes this is true. I tried the last spots on my desk with some dishwasher soap and the "rough"side of a sponge and that worked too. *facepalm*
Just soaked and washed the pads in the sink with some laundry detergent (colour)
Welcome to the non-vocal majority. It's good when folks identify issues and solutions, but understanding the true magnitude and risks from internet forums is all but impossible. A fun exercise before buying a car....find a couple of the major forums that discuss a model you are interested and see if there are any major issues....you start to wonder how any cars are still on the road
Raising issues is what leads to finding solutions we all benefit from. In my participation in this discussion I have been very careful not to state anything as fact that wasnt and to state things that could be concerns not being alarmist. Its when people start making straw man overreaction posts about Ebola and other silly remarks and calling people's concerns "ridiculous" that it creates a non-helpful non-constructive atmosphere.
My left cup had a bit more bass and volume than the right cup. I tried to tamper a bit with the headband to make the right cup push harder against my head. The two cups now are very balanced. For anyone who has channel imbalanaces, try squeezing the headband to make more seal in either cup. The more seal it has, the more bass n volume it will have in my experience.
Finally was able to put a couple of hours on my new cans last night. I just want to thank whoever returned these to Amazon because, as far as I can tell, there is nothing wrong with them. They definitely have a different sound then my HD595's. Going to need a little more time to elaborate further, but if anyone wants my impressions on the difference between the two, I will be happy to share.
