Dialed-in mixing, monitoring, and recording
The KLS 150 features an onboard Bass Control function, letting you adjust the low end by hand with a wide adjustment range for numerous pro audio applications. The dedicated dials are hidden beneath an easily removable earcup cover and feature tactile indicators, allowing you to adjust the bass without removing the headphones. The removable earcup cover also enhances the dual-shell design’s impressive passive isolation, allowing the KLS 150 to block out external noise for accurate live monitoring. Paired with dense earpads that create a strong seal, the dual-shell design also keeps headphone bleed at bay, a benefit that Sweetwater’s musicians, content creators, and studio engineers have found especially useful during recording sessions. The KLS 150’s impressive, acoustically optimized architecture ensures you get the most from the custom 40mm dynamic driver, delivering a balanced, low-distortion sound profile with exceptionally accurate low-end reproduction and an expansive 12Hz–28kHz frequency response.
Road-ready durability, studio-worthy comfort
Beyond their impressive acoustic design, the KLS 150 headphones feature an exceptionally comfortable, durable build that is ready to withstand the rigors of the stage, studio, and road. The KLS 150 features an ergonomic headband that evenly distributes weight, premium memory foam padding that conforms to your head for lasting comfort, and a corrosion-resistant spring-steel core with laser-etched reference markings to ensure a precise, consistent fit. The plush, roomy earpads complement the headphones’ glass-fiber reinforced construction, reducing pressure and fatigue while minimizing bulk and maximizing durability. Clearly visible, color-coded markings and foam inlays also make it easy to distinguish the left and right sides, even in low-light conditions. The 90º swiveling earcups enable effortless one-ear monitoring and complement the headphones’ foldable design.
