SE ELECTRONICS KLS150 STD PROFESSIONAL CLOSED-BACK OVER-EAR HEADPHONES
The sE Electronics KLS 150 Closed-Back Studio Headphones with Bass Control is a professional pair built for critical mixing and monitoring sessions. Custom 40mm dynamic drivers deliver powerful, balanced sound with detailed reproduction across a wide 12Hz to 28kHz frequency range. Their passive Bass Control system lets you adjust the low-frequency response to suit your preferences, helping you make confident mixing decisions across different playback systems.
Advanced dual-shell earcups provide strong sound isolation, making focused monitoring easier in noisy environments while reducing spill during recording. Leatherette earpads filled with memory foam adapt comfortably around your head during longer sessions. Their glass-fibre-reinforced construction and corrosion-resistant spring-steel components provide lasting durability without making the headphones unnecessarily cumbersome. A detachable locking cable, folding design, USB-C adaptor and protective drawstring pouch make them equally practical in the studio and on the road.
Make confident mixing decisions
Custom-engineered 40mm heavy-duty dynamic drivers produce powerful, well-balanced sound with plenty of detail. Their wide 12Hz to 28kHz frequency range extends beyond the audible range at both ends, supporting clear reproduction throughout your mix. Accurate low-frequency performance helps you judge kick drums, bass instruments and overall tonal balance more confidently. This makes the KLS 150 suitable for critical monitoring and mixing where dependable translation matters. With a 39-ohm impedance and 98dB sensitivity, the headphones are designed for professional studio, live and mobile monitoring applications.
Tailor the bass response
Passive Bass Control knobs inside both earcups let you adjust the low-frequency response according to your listening preference or current task. The system works acoustically, so it requires no batteries, software or additional processing. Matching the control position on both earcups maintains balanced reproduction between the left and right channels. Once adjusted, the removable covers protect the knobs against accidental changes during use. Reinstalling the covers also provides the highest available level of sound isolation, giving you a secure setting that stays consistent throughout recording, editing and mixing sessions.
Stay focused in loud environments
The closed-back, around-ear design helps reduce distractions when monitoring in studios, venues and other busy environments. Each earcup uses an advanced dual-shell construction to improve isolation, allowing important details to remain easier to hear without continually increasing the listening level. This isolation also limits sound escaping into nearby microphones, reducing headphone spill during vocal and instrument recording. Leatherette earpads create a close fit around the ears, while premium memory foam adapts to the shape of your head. Together, these features support reliable monitoring while keeping extended sessions comfortable.
Ready for daily professional use
Glass-fibre-reinforced construction gives the KLS 150 the strength required for regular studio work, live production and travel. Corrosion-resistant spring-steel components support lasting reliability, while the folding earcups provide several compact storage options. The detachable straight cable uses a twist-lock connection to help prevent accidental disconnection during use. A protective drawstring pouch keeps the headphones together during transport, and the supplied 3.5mm to 6.35mm screw-on adaptor supports common professional audio equipment. A 3.5mm to USB-C adaptor is also included for connecting compatible computers and mobile devices.
