AKG K240 Studio Semi-Open Headphones

The K240 Studio is a semi-open, over-ear headphone that has been a fixture of tracking rooms and edit suites for decades. Its semi-open design and 30 mm XXL transducers with Varimotion diaphragms give a spacious, natural sound that is comfortable for long sessions, while the self-adjusting headband keeps a light, even fit.

The semi-open enclosure suits mixing, editing, and general studio monitoring where a little openness makes the stereo image easier to judge. The cable is detachable for easy replacement and the earpads can be swapped when they wear, so the headphone stays in service for years.
