Professional semi-open studio headphones

The AKG K 240 MK II are professional over-ear semi-open headphones built for musicians, producers and engineers who need accurate monitoring during recording and mixing sessions. Their semi-open design combines the airiness of open headphones with the powerful bass response of closed models. A self-adjusting headband and replaceable earpads ensure comfort during long studio work.

Thermals noise and power draw

As passive wired headphones they generate no heat, produce no fan noise and draw no power from the source device. The 55 Ohm impedance and 104 dB SPL/V sensitivity allow them to reach high sound levels from standard studio interfaces or portable equipment without requiring a dedicated amplifier. Maximum input power is rated at 200 mW for safe operation.

Detachable cables with mini XLR

A professional mini XLR connector on the left earcup accepts the included 3 m straight cable and 5 m coiled cable, both terminating in a convertible jack plug for flexible connectivity. Replaceable earpads and the detachable cable design extend service life in demanding studio environments. Buyers needing wireless operation or active noise cancellation should look elsewhere.

Questions about this item

How do I connect the mini XLR cable to the headphones for the first time?

Insert the mini XLR plug into the socket on the left earcup until it clicks; the 3 m straight and 5 m coiled cables both use this connector.

Which parts can I replace when they wear out?

The earpads are replaceable; the detachable cables and convertible jack plug can also be swapped if damaged.

What is the maximum input power before the drivers risk damage?

The maximum input power is 200 mW; sustained levels above this can overheat the 30 mm XXL transducers.
