What reviewers said
AKG K240 MKII
The Austrian K240 MKII is a semi-open, wired over-ear headphone built for studio monitoring, using 30 mm XXL Varimotion drivers to deliver a broad dynamic range and precise sound. It includes a self-fitting headband, swappable ear cushions, and two cable options (straight and coiled) for flexible use. With a 55-ohm impedance and 91 dB sensitivity, it's suited for professional setups but not for noise isolation or portable use.
