This guy (Tumblr co-founder) tried pretty much every headphone (even crazy expensive $5k pairs) and really likes the Bang & Olufsen H6.
Been wanting to get a pair. East Dane sells them and discounts them during sales FYI...which combined with Canadian exchange rate makes for a pretty good deal.
I have a 1970s Bang and Olufsen turntable from an estate sale. It's awesome, but the cartridges are a proprietary design and replacements are $$$
This guy clearly has a strong idea of what he likes, but it would be a mistake to apply his ratings to yourself unless you you're pretty sure you like the same sort of sound. B&O is more or less a lifestyle/fashion brand like Beats (except their market is much higher end) - the stuff looks nice, but can be beat on sound for considerably less money.
They look great. The performance is mediocre. I think that they are the Hugo Boss of audio equipment, though the analogy is far from perfect.
I personally like Sennheisers and I'm really in love with V-Moda right now. The Crossfade M-100s are very clear for a broad range (http://v-moda.com/crossfade-m-100/), but honestly, the LP2 work just as well, at least for me: http://v-moda.com/crossfade-lp2-matte-black-metal/ You can totally nerd them out as well, but I mean, do you want to? (fwiw, I got my son a pair, with like, initialized shields, but it's super nerdy.)
The trendiest and best looking headphoens that I've seen in a minute are Master and Dynamic: http://www.masterdynamic.com/ Every tragically hip boutique, from Colette to Fred Segal, are carrying their stuff. I've only had a chance to try them out once, and the sound was good. But they look pretty awesome, and the clean aesthetic will match your version of Margiela well. (0)
V-moda is the perfect fashion headphone brand imo, they look great, but are also built solidly and sound great. I disagree about the LP2s, I find that the m100 sounds significantly better. The master and dynamics sound pretty good, but at $400 there are better picks, like the oppo pm3
Someone mentioned the wirecutter earlier, seconding it as a solid place to get recommendations for electronics
