Item number
K 240 DF 2058Z0016
• 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 240DF 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.
