Status, October 2026: current. KRK still lists it.
What it is
The KNS 8402 is a pair of closed-back, over-ear studio headphones from KRK, announced in August 2021 with the smaller KNS 6402 as the successors to the KNS 8400 and KNS 6400 (bonedo, KRK product page). The 8402 differs from the 6402 in its memory-foam ear pads and an in-line volume control.
It uses 40 mm neodymium drivers with a stated frequency response of 5 Hz to 23 kHz, a nominal impedance of 36 ohms and a sensitivity of 97 dB SPL at 1 mW. KRK quotes up to 30 dBA of ambient noise isolation. The headphones weigh 247 g, and the ear cups rotate 90 degrees.
The 2.5 m detachable cable ends in a gold-plated 3.5 mm plug with a screw-in 6.3 mm (1/4") adapter, so it fits a phone or laptop as well as a mixer or controller. At the headphone end, a sub-mini plug turns clockwise to lock into the ear cup socket, and the volume control sits between the cable and the headphones. The cable, ear cushions and head cushion can all be replaced; KRK sells a 2.5 m coiled cable and 3 m and 10 m straight extensions separately.
The box holds the headphones, the cable, the in-line volume control, a protective soft bag, an antimicrobial cleaning cloth and the user manual.
