The AKG K 240 Studio Professional Semi-Open Stereo Headphones are over-ear pro headphones ideal for precision listening, mixing, and mastering. They feature semi-open technology for solid bass and clear highs, and a patented Varimotion-diaphragm 30mm XXL transducer for accurate signal transfer and a wide dynamic range. The ergonomic design includes comfortable, padded earcups and a self-adjusting headband for long working sessions. A single-sided cable with a professional mini XLR connector allows for easy replacement, and the nearly 10-foot cable has a convertible jack plug for connecting to portable equipment. The headphones come in black.
