I saw this post earlier in the thread, and I couldn't resist replying to it and others that are questions peoples' concern over aesthetics.
Believe it or not, some people who visit head-fi aren't audiophiles. Some people just like collecting headphones and audio equipment. That doesn't mean they're not into music as well, but rather that they don't prioritize fidelity to quite the extent of the audiophiliacs. I've seen plenty of threads criticizing these folks for caring about "fashion" and for being "fashionistas." That to me is quite the holier-than-thou attitude.
It's obvious people care about design enough for companies to try to milk that, for better or worse. Now if only they'd concern themselves with more tasteful design.... *ahem.*
