Active moving-coil tran ;ducer.

At high frequencies, the passive diaphragms are

acoustically transparent­the K-240 operates as an open-air phone, thereby

allowing sound to enter the ear in a natural manner

maintaining a smooth and transparent top end.

At low frequenoes, the passive

diaphragms create semi-sealed

enclosure providing a flat and extended

bass response.
