Accurate, Reliable, Comfortable (and Affordable) Headphones

The KRK KNS6400 closed-back headphones give you the ability to monitor back and forth between speakers and headphones with a freedom you'd never have thought possible. Traditionally, having to switch to headphone monitoring has represented a "disconnect" of sorts in the recording process. You often find that those comfortable, ruggedly built headphones you love bear little sonic resemblance to your trusted monitor speakers. Drawing upon their 20-plus years of experience in studio sound, KRK has, fortunately, solved this dilemma with their KNS series headphones.

With the KRK KNS6400 headphones, monitoring on cans is no longer a jarring experience! Voiced to remain true to the character of KRK's class-leading studio monitors, the 6400s are designed to be a true reference monitor - allowing you to record and mix the same way you would using speakers. Exceedingly accurate, the 6400s have a natural, wide frequency response with a silky, articulate high end, and extended low-frequency definition that ensures that the bass component of your music is accurately reproduced. The robust dynamic range exhibited by the KRK KNS6400 serves up consistent low-distortion detail and clarity.

In the design of the KNS6400, KRK has given comfort a high priority. These circumaurals cradle the ear to remain comfortable during marathon sessions. The KNS6400s are also thoughtfully spec'd out with replaceable parts, including a detachable, high-durability, oxygen-free copper cable. Delivering accuracy, comfort, and reliability, these headphones are designed from the ground up for pro monitoring - allowing you to trust your headphones as never before.

krk 6400 ! MY FLOWER

RECEIVED TODAY IN THE MAIL ! THE SOUND IS BETTER REPRESENTED THAN MY BEAT AUDIO STUDIO HEADPHONES ! BETTER IMAGE OF INSTRUMENTS . CLARITY IS JUST ENOUGH. THE MIDRANGE IS AMAZING. AND THE LOW END ( THE BASS ) OF THE SONGS I PLAY THROUGH SOUND ACCURATE AS I CAN REMEMBER THE SONGS IN MY CAR. I PLAYED ROCK N ROLL , HIP HOP , AND R&B SONGS TO TEST IT . AND ALL GENRES SOUND GREAT.

Perfect Headphones!!

These headphones are great. From the second I plugged them in I was amazed at how great the sound was. These headphones have a pretty flat sound which is exactly what I was looking for since I needed new headphones for my home studio. I have not listened to other music on them yet but I am pretty sure that would sound great as well. I would definitely recommend these headphones.

Quality, Balanced Sound

Quality headphones, so comfortable and great for music production, coupled with the VRM box, it can do wonders for people who don't have studio monitors. It's even great for casual listening. Overall, KRK just got it right!

Super Headphones

I use these phones with the VRM box and these sound amazing. With each change of room environment on the VRM box I actually FEEL the difference and I felt like I was actually in the that room. These are really nice headphones.

Somebody finally got it right.

And, it's no surprise it was KRK. I've used KRK V6 and V4 studio monitors for several years now and absolutely LOVE them. So, when I saw they had come out with headphones I was very interested. I've been using SONY 7506/V6 headphones for twenty years and, after comparing them with several brands in the recording studio, swore I'd never use ANYTHING else. My KRK's arrived today and I was first very impressed with the build quality and great features. A detachable, replaceable cord? YES! The attached, coiled cord on the SONY's has always been a design flaw in my book. And, I don't know HOW many pairs of phones, some very expensive, I've trashed in the recording studio after a client has stepped on, and shorted/pulled out, the cable. Next, the KRK's have replaceable ear and headband pads. Another SONY downfall. So,as great as all that is, none of it matters if they don't sound good. I pulled up the mix I'm currently working on, listened to it through the studio monitors "KRK V4's" then put on the KRK phones. VERY comfortable and great ear coverage. With my SONY's at hand, and ready to run a comparison, I hit play. The SONY's never came out of the bag. The KRK's sound EXACTLY like what I get from their studio monitors. There were none of the "well, maybe a bit odd in the mids or bass-heavy" thoughts. These things are amazing, and that's a tragic understatement. NO distortion at WAY too high volume levels, clarity to spare, and the most incredible fit/feel of any phones I've ever used. Sorry SONY. I'll always love ya, but KRK just took your job. Final thought... GET THESE NOW!
