KRKKNS 6402 Studio Headphones - Black
1/5
Independent shopping perspective
The Korena take
KRK KNS 6402 studio headphones use a closed-back, around-ear design with up to 26 dBA of isolation. That isolation reduces headphone bleed into microphones during recording and helps keep outside distractions out of the listening session. The headphones are intended for critical listening, tracking, editing, mixing, and general listening, with a listed maximum SPL of 122 dB. Impact-resistant plastic construction keeps weight to 202 g without the cable, while the pads and cable are field-replaceable.
Strong match
Who this is for
- Recording sessions where reducing headphone bleed into microphones matters.
- Tracking, editing, mixing, and other critical listening work in distracting environments.
- General listening when closed-back isolation is part of the requirement.
Consider the trade-offs
When to look elsewhere
- Listeners specifically seeking an open-back headphone design.
