that's kind of question that usually gets me into trouble. ^_^ Because no matter what I say, someone somewhere will figure out a way to argue that he or she has listened to another setup with another headphone that is way better.
There is no perfect headphone out there, and each person's hearing and music preference is different. I respect everyone's opinion. That being said since i said that i will try to answer everyone's question, i will go ahead and say "yes, on top of my head i can't think of any headphone below $400 that is better than HE-400 overall." I admit that i am probably the biggest ortho fan on the planet. ^_^ I think that orthodynamic headphone is superior to dynamic headphone due to the nature of its driver.
