Description
When you need to shut out the world and just hear the mix, the Koss Quiet Zone QZ PRO combines two layers of noise reduction. Soft leatherette closed cushions seal around the ear to block ambient sound and preserve low-end response, while onboard active noise reduction (ANR) circuitry uses tiny mics in each cup to generate anti-noise signals that cancel out droning background sound. Don’t need it? Flip the switch off and listen passively.
Beyond the quiet, the QZ PRO is built for real listening: a dynamic driver spanning 40-20,000 Hz delivers deep, controlled bass and a balanced midrange, so vocals and instruments stay clear whether you’re reviewing a mix, checking a set, or just relaxing on a long trip. The fully collapsible design and extra-padded headband make it easy to fold down and stash in a bag, and it’s light enough for extended sessions without ear fatigue.
