A few months ago, I posted a picture of these, the Audio Technica ATH-ESW9. They cost me about $265 and were the best damn portable headphone I could find. The housing is made of African paduak wood and the earpads are made of lambskin. They sounded absolutely amazing and when I sold them (due to a significant lack of money) I swore I would buy another pair.
Enter the new limited edition ATH-ESW10JPN from Audio Technica. They are limited to about 1500 pairs worldwide. The housing is crafted of North American black cherry wood and the earpads are lambskin once again. And "The outer finish is done with Japan's most renowned lacquer craftsmanship in Echizen." Initial reports from head-fi are that they sound fuckin' awesome. I find that the great thing about Audio Technica is that they back up their great design with great sound.
The cheapest price online is ~$530 but I bought them from these guys with 30% cash back.
Also, the ESW9 is available on eBay for less than $190 after cash back. I could not give a higher recommendation for any portable headphone I have ever tried.
Here are some pics.

The Sennheiser HD-580 is more my idea of Modernist headphone design (and leagues better-sounding)
The HD-580 Jubilee, HD-600, and HD-650 lose a bit of the design purity of the '580 with their carbon fiber bits and metal grilles. The new Denons are a little bit more old school, with the metal bits and bolts in place of the molded smoothness of the Senns, and the wood cups on the more expensive models. 
But the most stylish headphones ever, if not the best-sounding to my ears, have to still be the Sennhesier Orpheus. 

The Denons, however, are quite nice. I've never heard a pair of Stax headphones, but I would like to.
