SE ELECTRONICS / KLS150

The "KLS 150" is a professional-grade, closed-back, over-ear monitor headphone. It features custom 40mm drivers and an innovative bass control system that allows for independent low-frequency adjustment for the left and right channels.

■ Custom-engineered 40mm high-durability dynamic drivers
・ Equipped with proprietary 40mm custom dynamic transducers (featuring neodymium magnets), these drivers deliver a powerful, nuanced, and well-balanced sound with exceptionally low distortion. The low-frequency range is precisely tuned to ensure faithful reproduction of mixed audio across a wide variety of playback environments.

■ Bass control function for on-the-fly low-frequency adjustment
・ Bass controls are integrated into both the left and right earcups. Using an acoustic-based design, these controls allow for seamless adjustment of the low-frequency response—ranging from -5 dB to +5 dB—without introducing signal loss or phase shifts. This versatility makes them ideal for everything from studio mixing and live stage performance to casual music listening.

■ Highly durable design featuring glass-fiber reinforced components and spring steel
・ Glass-fiber reinforced components provide an optimal balance of lightweight construction and superior strength. Furthermore, the use of corrosion-resistant spring steel ensures reliable, long-term performance, even in the demanding environments of professional studios, live stages, or touring.

■ Detachable locking cable and 90-degree swiveling, foldable design
・ The headphones feature a detachable cable with a locking mechanism to ensure a secure connection. The earcups swivel 90 degrees, facilitating easy single-ear monitoring, while the foldable design simplifies transport and storage, helping to streamline your workflow.

■ Ergonomic design for even pressure distribution and high-quality synthetic leather earpads
・ Outfitted with high-quality synthetic leather earpads that offer excellent comfort, sound isolation, and a premium feel. The ergonomic design ensures even pressure distribution, while the adjustable headband—complete with clearly visible adjustment markers—maintains a comfortable fit even during long sessions. ■ Extensive optional accessories for customizing appearance and components (coming soon)
・ A range of separately sold accessories—including interchangeable ear cup covers in various colors, velour ear pads, coiled cables, and a protective carrying case—allows you to personalize both the look and the feel of your headphones.
