The Koss QZ99 delivers high-quality audio with exceptional noise isolation in a comfortable around-ear design. A stereo/mono selector switch adds versatility while the built-in volume control allows quick level adjustments on the fly.

The Koss QZ99 is a closed-back headphone built for clear monitoring in noisy environments where focus matters. Its neodymium drivers deliver detailed sound across a wide frequency range, making it a practical choice for event production, venue installs and DJ booths.

Comfort comes from the padded adjustable headband and thick Pneumalite around-ear cushions that create a secure seal. The closed-back earcups and noise-isolating design help block external sound so you can concentrate on the mix rather than the room.

A single-sided coiled cable reduces tangles and gives you flexible reach, while the gold-plated 3.5 mm plug and included 1/4″ adapter connect easily to both consumer and professional gear. The on-ear stereo/mono switch and volume control add everyday convenience without extra accessories.
