Product Description

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.

Good quality, great sound...
What is your opinion of this product?
I have big ears so I was concerned with the depth and circumference of the cups. If they're not deep enough, I get a headache pretty quick. The 6400s seem to be just about the right size for me. I can wear them for hours.

I love these HEADPHONES!!
What is your opinion of this product?
Excellent pair of headphones. These produce a very true high quality studio sound. I wouldn't necessarily use headphones for mixing but out of all the lower and mid-range studio headphones I've owned, these sound the best.You really hear the quality when it comes to editing Vocals!!

Great Balanced Headphones
The quality is great. They have just enough ambient noise reduction without creating that feeling of your ear drums being sucked in (IE: Active Noise Cancelling Phones). The bass is not exaggerated like Hi-fi headphones so they are definitely solid for mixing and tracking. The sound is comparitive to the ATHM40FS by Audio Technica, but are a little brighter, and they have an 1/8" connector with adapter. Overall, a very solid build.
Detachable cable is the only feature worth noting outside of normal headphones.
Very easy. Just make sure detachable cord is inserted completely, and locked.
Great value for it's price range. Although I use tuned monitors, I can reference tracks on these well. I noticed that these bring out a lot of detail in the higher end of the spectrum for mixing, and they also have a natural stereo field.
