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.
