sE Electronics KLS 150 Studio Headphones with Bass Control

The sE Electronics KLS 150 is a professional closed-back, over-ear headphone designed for critical monitoring, mixing, recording and live sound. It's sE's first headphone, bringing the brand's studio experience to a new category with a focus on comfort, controlled low end and strong isolation. At its core is a custom-engineered 40 mm heavy-duty dynamic driver with a neodymium magnet, delivering powerful, detailed and well-balanced sound across a 12 Hz to 28 kHz range. The innovative Bass Control lets you tailor the low-frequency response to your preference or application. It's a passive, purely acoustic system, set with a dial under each earcup cover, and the interchangeable covers protect the dials from accidental adjustment. For long sessions, high-quality leatherette ear pads and premium memory foam adapt to the shape of your head, while the dual-shell earcup design keeps outside noise out and minimises headphone bleed when tracking. Glass-fibre reinforced construction and corrosion-resistant spring steel keep the weight to 335 g without sacrificing durability. Practical details include a detachable cable with a twist-lock connector, laser-etched markers for a repeatable fit, 90° swivelling earcups for one-ear monitoring and multiple folding options for storage and transport. The KLS 150 comes with a 3 m straight cable, a 3.5 mm to 6.35 mm screw-on adapter, a 3.5 mm to USB-C adapter, a protective drawstring pouch and an earcup opening tool.
