About the KRK KNS8400

David Brown

The link between your ears and your music

Recording musicians — from first-timers to seasoned pros — rely on their ears to guide them in the studio. Those ears would be lost without a great pair of headphones to feed them accurate sound. That's the crucial role filled by the KRK KNS8400. These full-size headphones are designed with musicians, engineers, and producers in mind, so they can hear nuances that might escape less attuned ears. They offer fine detail across a broad frequency range, giving equal attention to deep bass, warm mids, and clean highs. These headphones can help you identify what is missing from your recording as well as pinpoint any noise that shouldn't be there.

Excellent noise isolation

The KNS8400 headphones feature a closed-back, circumaural design. That means the soft, cushioned earpads fit completely over your ears, forming a seal that keeps sound from leaking out of or into the headphones. This allows you to clearly hear your monitor mix in the headphones without other live instruments bleeding in. Also, sound from the headphones won't leak out into live mics. This makes them ideal for performers who depend on good headphone monitoring to deliver that killer take. Plus, they're comfortable enough to wear for hours for all those retakes and overdubs.

In-line volume control

Normally, if you want more volume in your headphones, you need to reach for the mixing board or get the engineer's attention. But with the KNS8400 headphones, you can maintain volume control with the in-line remote. It's removable if you'd rather let the control room handle your monitor levels. The headphones also come with a screw-on 1/4” adapter, so you can plug them into a mixing console or use the cable's miniplug connector with your smartphone outside the studio.

Features

KRK Sound: The KNS8400 headphones have been 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. KRK headphones provide incredibly natural frequency response that gives you a reference standard unaffected by your location.

Neodymium 40mm driver. The KNS8400 headphones employ high-efficiency 40mm drivers that deliver a large dynamic range with extremely consistent low-distortion detail and clarity. The 40mm drivers are exceedingly accurate, natural and offer wide frequency response. Extended low frequency definition, ensures the bass component of your music is accurately reproduced, and is not lost.

Closed Back Design: 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.

Memory Foam Earpads: The KNS8400's earpads utilize the latest in acoustic memory foam technology to ensure class leading performance in both reproduction and isolation. Memory phone also adds to the comfort of the headphone, even over extended periods of use to avoid feeling uncomfortable during long sessions. The special memory foam conforms to the ear to help ensure an improved fit.

Detachable Cable & Connector: The KNS8400 uses a high durable 8.2' single-sided straight cable with oxygen-free copper wires. The 1/4" jack plug can be unscrewed to reveal a 1/8" plug for laptops and portable media players.

In-Line Volume Control: KNS-8400 features an in-line volume control with a sleek profile which is designed not to catch on clothing or instruments during performance. The volume control also uses a high quality long-life fader and comes in a sturdy enclosure.

Portable: Adjustable, foldable driver enclosures provide comfort and portability. Included is a soft carrying case embossed with the KRK logo for traveling or storage when not in use.
