Excellent set of reviews!
On the 900's - the reason I didn't keep mine had to do with the "wings". I could hear them microphonically whenever I'd move my head.
It was a subtle squeaking sound from their spring mechanism.
I guess, with hindsight, that I could have phoned AT USA in Ohio and asked for advice - maybe there's some lube or some other way to quiet
that sound...
Yep, I can confirm that I hear it too. There is an occasional "tense spring" sound, when you move your head or change your listening position. Apart from the thing you describe as "spring mechanism", their cable is also too sensitive, because every time it touches a part of your body or any other object, you hear this in your ear cups (as well as with other headphones, of course, but with these it seems more pronounced). This is what also contributes to what I referred to as "plasticky" feel of these headphones in my comparison. They seem too "touchy-feely" in some regards. You have to learn to be completely still, if you want to enjoy music with them ;)
