KRK KNS6400 Studio Headphones

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 accurately enjoy your music with the consistent voicing philosophy and honest reproduction top producers, studio musicians, performers and engineers have come to trust. KRK headphones provide incredibly natural frequency response that gives you a reference standard unaffected by your location. Day or night. Studio or home. Without disturbing others. Without compromising your tracks. Passionate about music and interested in experiencing the artist's vision as it was intended to be heard? Then experience KRK.

Whether you are listening to some tracks, or tracking your next recording, the KNS-6400 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.

  • Voiced to remain true to the character of KRK's class leading studio monitors, developed with 25 years of years of experience in studio sound.

  • Extended low frequency definition, ensures the bass component of your music is accurately reproduced, and is not lost.
