Being able to discern the most subtle differences in pitch, timbre and tone helps you to get it right every mix, every take, in every performance.

Isolating memory foam in the ear cushions delivers improved low end response and because they gently conform to your unique head shape, you'll be comfortable wearing them all day.

With a detachable and replaceable locking cable, rotating ear cups for travel and storage and replaceable ear and head cushions, the KNS 8400 headphones are durable whatever you put them through.

A low pressure headband system and self-aligning yoke system ensure comfortability and the best possible fit.

Press Reviews

"I've just fallen in love with a pair of KRK KNS 8400s. The detail in the sound is amazing. It really felt like I was hearing it in the studio."

- Audio Media Magazine

"I found the KNS-8400 to be good for tracking, offering minimal fatigue on the top end, slightly scooped out low mids (around 200 to 400 Hz) and just enough bottom."
