Whether you are listening to some tracks, or tracking your next recording, the KNS6400 gives you the famous KRK sound independent of your monitors. KRK Headphones provide a precise listening experience that takes you from personal studio to commercial studio to on-the-go track evaluations — and they allow you to evaluate and enjoy your music with the consistent voicing philosophy and honest reproduction top producers and engineers have come to trust. The KNS6400 headphones have a closed-back around-the-ear design that 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 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.
