Well, I went ahead and ordered Westone 2's from B&H. My biggest reasons for doing so are the cords (I absolutely hate bulky cords with memory), and because I read a few complaints from people with GR07's that lost a channel due to wire strain. That, combined with the fact that Westone seems to have great customer service, made me spend the extra $60 and get something that will be a bit less "fun" sounding.
I'm looking forward to hearing the detail and clarity that the Westone 2's will hopefully provide. At the end of the day, if I'm not a huge fan of the sound signature... well, that's what they make equalizers for. 
Interestingly enough, I was originally going to buy some IEMs for just listening to music on my laptop, and occasionally from a portable player (probably iPhone 4S). Then, I decided that it would nice to be have something that's comfortable enough to work out in as well. THEN I toyed with the idea of using them on my desktop for games as well (which sounds like a bad idea after doing some more research). So, I'll be retiring my current gaming headset - Sennheiser PC-160 - and making way for the ATH-AD700's that I ordered at the same time. You guys are a bad influence as far as my wallet is concerned. 
Thanks for your opinions and advice everyone!
