sE Electronics KLS 150

The sE Electronics KLS 150 are professional closed-back, around-ear studio headphones built for monitoring, mixing, recording and live sound (FOH and monitors). What sets them apart is the adjustable bass control: instead of a fixed response, you choose how much low end you hear.

The Bass Control is fully mechanical, with no DSP, batteries or electronics: you set it with dials on each ear cup, with numbered markers so you can repeat exactly the same setting. The swappable ear cup covers protect the dials so they don't get knocked mid-session.

They use a custom 40 mm dynamic driver with a neodymium magnet, low distortion and accurate low end. The dual-shell ear cups isolate you from outside noise and keep headphone bleed out of the mics when recording. With 39 ohm impedance they work well with laptops, phones and audio interfaces without needing a powerful headphone amp.

Built to last and for long sessions: memory foam pads with leatherette covers, ear cups that swivel 90° for one-ear monitoring and a detachable cable with a locking connector.
