The incredibly versatile KRK KNS 6400 Headphones provide KRK sound quality in a unit that will benefit you in your home studio, commercial studio and even when travelling.
Legendary quality audio
Trusted by music professionals from producers, musicians, engineers and everything in-between KRK is a name that holds a lot of credence, and you’ll see why with the KRK KNS 6400 Headphones. Offering accurate reproduction provided by a natural, wide frequency response the headphones present sounds as they should be heard; perfect for monitoring.
The closed back design of the KRK KNS 6400 Headphones and advanced memory foam-padded ear and head cushions provide excellent isolation and comfort for fully immersing yourself in tracks whether you’re listening to music or monitoring tracks that you’re working on. This isolation also eliminates residual sound getting into open mics.
Also, for added comfort when using over long periods of time, the KRK KNS 6400 Headphones are constructed of a lightweight, yet sturdy material, and the self-aligning yoke system shapes itself to your head for an excellent fit along with a headband that’s adjustable to exert as little pressure as possible whilst remaining in place.
The construction of the KRK KNS 6400 Headphones allows you to replace ear and head cushions along with the locking cable. They also have rotatable ear cups that are excellent for ‘on-shoulder’ monitoring and reduce their overall size for travel.

Upon first use, the headphones didn't seem to colour the sound whatsoever, they gave a really flat response, ideal for use in a mixing environment. When I listen to past work of mine, I began to notice all kinds of mixing errors that previous headphones kept hidden away. The highs are bright and crisp, mids are clean, and the bass is clear - it's not dominant, but it's there. The 6400's frequency response is from 10Hz to 22kHz, which is wider than the human ear's, which shows you what these are capable of.
My first impression of these headphones was "wow, these are comfy!" as I have had comfort problems with past headphones. The longest period I have used these so far is for 2 hours, after which I did start to notice the clamp - but given that clamp has been a problem with all my headphones, it may just be my head!
I find that the closed-back design of the 6400's is flawless. The headband has steel running through it, for maximum durability. The pads and cable are both replaceable - so should they ever become damaged they are easily replaceable, without having to shell out again for more headphones. Finally, the design of the headphones is undeniably modern, with the "metallic" approach, and colour co-ordinated left and right indicators.
Flaws (if any):
The only flaws I can think of are the discomfort I experienced after extended use, and that if used for personal listening during a long bus ride; for example, they appear bulky on the head.
For the price, I would rate these headphones a 10/10, but disregarding price I would give them a 9. Obviously, there are better headphones in the world, but you won't find better than the KRK KNS series for less than £150. Anyone with KRK monitors will know that despite KRK being "the new kids on the block" within the audio world, they can definitely be trusted to do an outstanding job.
