As more music is being made in bedrooms on computers, a cost-effective monitoring solution that offers a more "neutral" sound for DJ/producers compared to standard DJ cans is a must, and KRK seek to tick that box with this line of phones. If you’ve ever felt a need for a clear, crisp and virtually distortion-free reference of your mix — don’t look any further.

I noticed is that the KRK KNS 6400 has a very impressive soundstage for a closed headphone… At times I'm even fooled into thinking I have an open headphone. If I had to only use the KRK KNS 6400 as my primary headphone, I'd be perfectly satisfied.

..the KNS-6400 would be preferred for instrument and vocal overdubbing applications. Their increased midrange focus and lack of distracting bottom end thump helps singers and instrumentalists focus on pitch and melody. I found that performers liked both KRK models for overdubs (split 50/50 between KNS 6400 and KNS 8400).

The sound stage of the KNS 6400 is very similar to the KNS 8400s which makes them extremely good bang for the buck as a set of closed back gaming headphones. Just like its bigger brother it can be driven to within an inch of its life out of a normal sound card and that makes them ideal for gamers looking for a set of durable, high price / performance ratio gaming headphones.
