The K 240 Studio is an update of the "classic" AKG K 240 Monitor. The K 240 Studio delivers even wider dynamic range and higher sensitivity than its well-known and widely used predecessor. The secret to the semi-open K 240 Studio's sound quality is the new XXL transducers in acoustically tuned vented enclosures with circumaural (around the ear) pads. The circumaural pads envelope your ears nicely and reward you with smooth, solid bass and well-balanced, articulate mids and highs.

This keyboard also has Advanced Encryption Standard (AES), which is designed to help protect your information by encrypting your keystrokes.
