AKG K-240 MK II Semi-Open Back Headphones with Replaceable Cable

More Views


The K240 MKII are one of the best-selling headphone models from AKG, famous for their natural, pristine sound. Major benefits of these semi-open AKG headphones with dynamic full-range speakers include a punchy bass range, clear highs, and excellent comfort.

The AKG K240 MKII uses XXL speakers with Varimotion multiple-thickness diaphragms for dynamic transducers for higher sensitivity, a wider dynamic range, enhanced bass response, and higher sound levels. The circumaural (around-the-ear) pads are designed for hours of wearing comfort, while the steel-cable, self-adjusting headband construction and single-sided professional-quality audio interconnect ensure extended reliability in demanding professional studio applications.

Semi-open headphones, such as the AKG K240 MKII, combines the best features of both closed or sealed headphones and open air designs and relatively few disadvantages. Through careful attention to the control of resonances, a surprisingly realistic stereo sound field is developed, coupled with low distortion and extended low frequency response. Circumaural headphones encircle the ear, and provide a good seal. The AKG K240 MKII are comfortable to wear, provide good isolation, and result in a consistent sound from one wearing to another. Bass extension is excellent with the AKG K240 MKII because a very good air seal can be made against the head.
