The incredibly versatile KRK KNS 8400 Headphones provide KRK sound quality in a unit that will benefit you in your home studio, commercial studio and even when travelling.

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 8400 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 8400 Headphones and advanced cellular 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 8400 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 8400 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.

So how do the KRK KNS 8400 Headphones differ from the 6400 model? Well it's all in the detail, but it's the extras that really make the difference when you want true sound reproduction. These headphones have a number of aural improvements over its little brother that give you improved sensitivity, frequency response and isolation as well as improvements in comfort with the use of acoustic cellular foam for the ear cushions and a premium leatherette for the headpad finish. The KNS 8400 also sports an inline HQ control that is removable for easier volume control. See the comparison chart below to get a better idea of the differences between the two models.
