A new series of professional headphones has been introduced by KRK Systems, and the current offerings in the KNS series include the KNS-6400 and KNS-8400. These headphones boast an advanced transducer design, sonic accuracy, transparency, and a comfortable fit.

According to KRK, both the KNS-6400 and KNS-8400 provide honest reproduction that will benefit studio engineers, studio musicians, producers, and avid music fans alike. The new headphones provide a natural frequency response (10 Hz to 22 kHz on the KNS-6400 and a range of 5 Hz to 23 kHz on the KNS-8400) that gives you a reference standard unaffected by your location, notes the manufacturer. Both models have a detachable and replaceable locking cable, rotating ear cups for travel and storage, durable materials, replaceable ear and head cushions, and a number of of accessories.

About the KNS-6400 and KNS-8400, producer Rodney "Darkchild" Jerkins of Darkchild Entertainment comments, "They are lightweight -- not these big, old heavy headphones that you feel like you want to take off after wearing them for five minutes. Now when I take my mixes home or when I’m traveling, I can plug my KRK headphones into my laptop and feel like I’m still in the studio."

Comfort is indeed one of the selling features of the new headphones. Both have a lightweight reduced-mass structure with an adjustable low-pressure headband system, plus a self-aligning yoke that ensures the best possible fit. The acoustic foam ear pads gently conform to one's head shape while improving low-end response and providing a high level of sound isolation.
