As a /r/symphonicmetal fan, I completely agree with this.

HD 6x0s are old headphones made for old music. Said music genre was pretty much nonexistent at the time the HD 600 was released (as are many other modern genres that you mention), so it's obvious they weren't designed with that in mind. I prefer a number of newer and less expensive headphones.

I don't have a problem with people enjoying their 6x0s, I just want this kind of pretentious posts to stop.
