PRODUCT OVERVIEW
KNS6400
Listen Up. This is How Your Music is Supposed to Sound.
Whether you are listening to some tracks, or tracking your next recording, the KNS6400 gives you the famous 
KRK sound independent of your monitors. This closed-back around-the-ear design brings you closer to your 
music, and the highly isolated surround pads give you the freedom to immerse yourself in the sound without 
having your monitor mix ”escape” into open microphones -- and keeps live instruments out of what you are 
monitoring.  Having  “One  Voice”  that  consistently  gives  you  accurate  reproduction  of  your  music  or  mix  will 
help you achieve just what the artist intended -- especially if the artist is you.
KNS8400
Headphones for Educated Ears.
Looking for a pair of headphones that are specifically designed to replicate music as it should be heard with 
the ability to satisfy experienced ears? Get your head around this: KRK has always been focused solely on 
accurate monitoring. The KNS8400 -- with their ability to reveal exactly what you have on the tracks is an ideal 
choice for critical listening.  Being able to discern the most subtle differences in pitch, timbre and tone helps 
you to get it right every mix, every take, every performance. Isolating memory foam in the ear cushions 
delivers improved low end response and because they gently conform to your unique head shape you’ll be 
comfortable wearing them all day.
