I'm about settled on the d1001 for a lug back-and-forth to work, do-it-all headphone, mostly because I don't really see anything else on the market that fits in the same niche of circumaural, closed, and still (sorta) portable, unless you go up to the Edition 8 maybe. And on my budget that ain't gonna happen. (yeah, I know the CAL! is allegedly about the same, but I'm talking about any actual alternative. And I am considering the big black cans like the m50, srh440/840, but I'm thinking they're just too big and over-the-top for the office) I have read that the d1001 might be a little lacking in the sturdiness department though, and that makes me a bit concerned about it maybe being creaky, noisy, microphonic ... whatever you wanna call it. My head is LARGE which tends to bring out this problem ... my ES7 for instance creaks in the swivel joints every time my ears twitch. So, d1001 owners ... are you satisfied with the build quality? Any creaks? And most important, does it fit a big noggin?
