Comments about Krk Kns-8400 Studio Headphones:

I've used the poplar Beyer dynamic dt770s and don't like them because they have nothing above 10k. These are much more open sounding the only noticeable bump is in the low end around 150 hz. But knowing about it, it's easy to work around. I also like the volume control, good isolation, and they don't rattle when a singer is moving around which makes them good for tracking.
