Some people prefer the 700s> the 900s and vice versa, you kinda have to let your ears decide.The AD700 are strictly for jazzy/classical music and don't really fit if you're listening to rock or rap. On the other hand, they do make for great gaming headphones.
The HARX700's (and maybe even 900's) are great
after burn in, but unless you have a small head, the metal bars do tend to put pressure and become very uncomfortable after a couple hours or so of use (just my opinion). Sadly, I made the mistake by snagging the plug on my pair, so I'm either going to have to spend $10-15 to send/ship them in, or buy a new tip at radio shack and attempt to solder a new one on. I guess I've learned my lesson and should stick to coiled headphones (V6/7056/M50 etc) for studio/home usage as I tend to move around a lot between my computer/mixer/drums. But yeah, the 700/900's are pretty amazing for the price if you pay attention and take care of them Edited by Skylit - 11/23/10 at 9:58pm
