Summary: I'm going to level with you -- I bought these headphones for a reason that probably nobody in history has ever purchase the KRK KNS 6400s. I bought them because I thought I might be able to coax a good bass response out of them. I saw the graphs at HeadRoom and InnerFidelity and thought: "These things have the most extended bass response I've seen out of anything in its price range! Only a modded T50RP has that kind of extension under $100!
Pros: Excellent detailing, very well rendered mids, surprisingly good sub-bass, responds well to EQ, comfortable headphones, high isolation
Cons: Even after EQ, lack of bass impact due to an overdamped bass response, very unmusical with stock settings
Summary: KRK KNS6400 A detailed monitor
So I had to give the KNS6400's a shot because they were recommended to me based on my love for the SRH940 and other headphones that are all about mids and details. The KNS6400 is only $80 from Amazon, but I was lucky enough to have Tdockweiler let me borrow his pair for a while to audition and get a feel for them, so a huge thanks to him for letting me borrow the cans.

Excerpt: I bought these headphones because I've read that KRK makes one of the best sounding studio monitors so I figured their headphones must be great as well. The clarity is awesome with these headphones. I compared them to an extremely old pair of AKG headphones I have, which still work really well, and the KRK's output is a little louder and my highs and mids are clearer. The only I do NOT like about the KRK's is they lack bottom end.
Summary: These take a bit of getting used to. They sound quite middle-y and muffled at first but it is sounding better the more I use them. They are pretty comfy overall, but after a long studio session they do start to hurt my ears a bit. They are excellent for recording as there is no bleedthrough at all. Well made product, high quality. 4 out of 5.
Summary: Very good headphones. They have a great frequency range and seem excellent for mixing. They are also very comfortable even after long durations of wearing and are very well built. I would definately recommend to anybody looking for headphones for a studio.
