Well, what do you plan on using them for?
If you're just looking for headphones to listen to music and wear around, and are looking for quality, i'd say get the wesc. Although i would actually say just look into some real headphone companies and forget about both those companies if you're looking for some well built, long lasting headphones. I personally use the sennheiser hd 280 pro for editing and what not and i'm really loving them. Built so well and the sound quality is amazing.
If you're going to be pretty much just skiing with them, them i'd say go for the skullcandy icon/recruit. I gave my old pair to a friend of mine who rides, but in total it's been almost 2 seasons of use with them and they're still going fine. Plus, they're dirt cheap. I picked up 2 pairs for last season for $25 shipped. I'd say its not really worth spending the money on those bigger headphones for skiing, i think they're much more awkward for skiing with.
