The KLS 150 is a professional closed-back over-ear headphone designed for critical monitoring, mixing, recording, and live sound applications. Combining exceptional long-session comfort, precise low-end control, and outstanding passive isolation, it delivers the accuracy and reliability demanded by today's audio professionals.
At the heart of the KLS 150 is a custom-engineered 40 mm heavy-duty transducer that delivers a powerful, detailed, and well-balanced sound with exceptional low distortion. Its accurate low-frequency reproduction allows mixes to translate confidently across a wide range of playback systems, while the innovative Bass Control lets you tailor the low-end response to suit your personal preference or application. Whether you're mixing in the studio, monitoring on stage, or simply enjoying your music, the KLS 150 gives you full control over your listening experience.
Long sessions require exceptional comfort. That's why the KLS 150 features premium memory foam that adapts naturally to the shape of your head, combined with high-quality leatherette ear pads that provide outstanding comfort, excellent sealing, and a premium feel. The ergonomic design distributes pressure evenly, making it easy to forget you're even wearing the headphones.
The innovative dual-shell earcup design provides excellent passive sound isolation, making the KLS 150 equally at home in the studio and on loud stages. Superior isolation minimizes ambient noise during monitoring while also helping to reduce headphone bleed during recording sessions, making it an excellent choice for musicians, engineers, and content creators alike.
Interchangeable earcup covers allow you to personalize the appearance of your headphones while simultaneously protecting the Bass Control knobs from unintentional adjustment. Optional color variants make it easy to match your personal style, while additional accessories—including velour ear pads, a coiled cable, and a protective carrying case—allow you to configure the KLS 150 to perfectly suit your workflow.
Designed for the rigors of professional use, the KLS 150 combines exceptional durability with remarkably low weight. Its glass-fiber reinforced construction provides outstanding strength without unnecessary bulk, while corrosion-resistant spring-steel components ensure years of reliable performance on stage, in the studio, and on the road.
Numerous thoughtful details further enhance everyday usability. A detachable high-quality cable with a secure locking connector ensures a reliable connection, while laser-etched adjustment markers make it easy to return to your preferred fit. The 90° swiveling earcups allow convenient one-ear monitoring, and multiple folding configurations make storage and transport quick and easy.
The KLS 150 comes supplied with a protective drawstring pouch, a straight detachable cable, a 3.5 mm to 6.35 mm screw-on adapter, a USB-C adapter, and an earcup opening tool.
Built for professionals. Designed for everyday use. Engineered to help you hear every detail—and trust every decision.
