I'm not a fan of the look, like other people have said before, it looks like an evil HD800 lol. I started out with some IE8s, then TF-10s, B2s and then finally a pair of high end UM Miracles. The best decision I have made so far was to move to a full-sized setup.
The HD700 is *almost* as good as the HD800. The HD800 disappears on your head and the HD700 almost does that, but doesn't quite do it as well as the HD800. They are one of the most comfortable headphones I've worn. The 700s are like Sennheiser/Grado hybrids but leaning more to the Senn side.
