I remember reading quite a bit that the hd700 wasn't worth it, I'm so glad I got them anyways. A couple years ago when I first started paying attention to headphones, I started out with the Porta Pro, then moved quickly to the grado sr80. About a year after my next big upgrade was to the he400, which sounded amazing but was a little to far back in the mids. I spent 5 months making that decision and was strongly considering the momentum and the hd558. A year later is when I saw the deal of a lifetime on the hd700, which I had thought out of my range. During all this time when is see a sale, I'd usually bite so I could expand my horizons. Some i would like, some like the hd598 brought disappointment. This is the first headphone that out of the box I loved unconditionally, much like a fine steak, although I would not eat the hd700. It handles most genres quite well, which is important to me. It also doesn't hurt that it has an amazing look.
I'd write more, but im on a tablet.
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.
