Studio semi-open headphones

The AKG K240 Studio semi-open over-ear headphones are built for critical listening in recording, mixing and mastering environments. Their semi-open design blends the airiness of open models with the bass authority of closed backs. A self-adjusting headband and replaceable ear pads keep long sessions comfortable.

Wired analogue connection limits

A 3 m detachable cable terminates in a 3.5 mm stereo plug with a screw-on 6.3 mm adapter, so the headphones connect directly to audio interfaces, mixers or portable players. Passive operation means no batteries, no charging and no wireless latency. Maximum input power is 200 mW, so drive levels must stay within that ceiling.

55 ohm impedance and 104 dB sensitivity

At 55 ohms and 104 dB SPL/V the K240 Studio reaches loud monitoring levels from typical studio gear without a dedicated amplifier. The 30 mm Varimotion transducers cover 15 to 25 000 Hz, revealing detail across the audible band. Very low-impedance sources or extremely high-output stages may exceed the 200 mW limit.

Questions about this item

Which connector should I choose between the 3.5 mm plug and the 6.3 mm screw-on adapter?

Use the 3.5 mm plug for portable devices and the 6.3 mm adapter for studio gear; both connect to the same detachable 3 m cable.

What does the 104 dB sensitivity figure mean when I plug these into my audio interface?

At 1 V input the headphones produce 104 dB SPL, so typical interface headphone outputs drive them to loud monitoring levels without extra gain.

How does the 55 ohm impedance affect the headphone output I need?

The 55 ohm load is well suited to standard studio headphone outputs; most interfaces deliver the rated 200 mW maximum power cleanly into this impedance.
