K 240 DF


  • Radio station reference headphones
  • Diffuse-field equalized, designed strictly to IRT (German Institute for Radio Technology) standards
  • Single cable for ease of use
  • Semi-open, circumaural design

    • Used as reference headphones by many radio stations worldwide, this model has been in the AKG catalog unchanged for ten years and has become a classic by now.

    With their flat frequency response, these headphones provide an uncolored sound. The diffuse-field equalized K 240 DF meets not only the stringent criteria of the IRT standard but those of professional sound engineers as well.

    Created to fulfill the international IRT specification, the K 240 DF establishes a uniform quality standard free from environmental variables. In fixed apposition to the ears, the sound output quality is unchanging and reliable – as opposed to loudspeaker monitors, sound from which is markedly influenced and colored by variations in control room architecture and furnishings.
