Yeah, a friend of mine pointed that out the other day. Quite the deal, to be honest!
I too, found the aesthetics to be pretty interesting. Simple, but somewhat unique. I initially wanted to 4D carbon fibre vinyl wrap the cups for sexiness, but I went against that as the vinyl would just peel off too easily.
Before I acquired a pair, I read on the threads that the cups scratch really easily, but that wasn't the case, as I found it rather hard to scratch (unintentionally). I did, at one stage, run my nails over the cups (stupid idea, I know) to see how easily they scratch. I left them in a drawer with all my other cables and jacks, and yet no scratches as yet. But yeah, they're certainly well built.
