No kidding it won't be a thrash pair, but I also don't want to worry about the cup snapping off when I put it on my head 10 years down the line. I expect my headphones to last at least 10 years if I'm paying $1k. The fact of the matter is, the D7000 has a tiny screw that could easily snap under NORMAL circumstances that holds the cup to the band.
Yeah it needs to be very long lasting. I also corroborate high price and quality of materials to longevity.
I don't know about the AH-D2-5-7000 fail rate for that screw, but I always found Japanese technology products to be built "just strong enough" for the usage that one should do of them, but "not much stronger" after that; so that you need to stay careful with them. I think that just the way of Japan, to be sensitive and respectful to the others, the animals, the nature and finally one's own goods.
