How are you basing your opinion? IMHO, you are wrong. The aesthetic appeal adds some value, but not enough to spend even $5 on if the sq isn't there.
I've had the ESW10s for a couple weeks now, and the 9s for about a year. For those of you weighing whether or not the price of the 9s or 10s is "worth it" when compared to full-sized headphones, you really need to consider what full-sized headphones you're comparing, and why the heck you want a portable headphone in the first place.
Think of the price of the some of best portable amps. They're often as much or more than decent entry-level home amps that would make more sense and sound even better depending on the headphone used. You're paying for the quality AND portability, not one or the other. If you want a home rig, you can get better sq, depending on your tastes AND the rest of your system, for less money. If you're looking for excellent sq in a portable rig, that's what you need to pay for if that's what you want to get.
Anyway, I'm quite happy with the 10s, though they're a bit more fatiguing the the 9s if you plan on listening for hours on end. I do think they're worth the money if you're looking for a portable, closed headphone that sounds great without an amp. If you're looking for something else, get that. No big deal.
