AKG K 280 Parabolic

 AKG sets a new standard in headphones technology.  An  "acoustic lens"  provides a new level of sound quality. Each channel uses two transducers whose diaphragms form tangent planes to a paraboloid as shown.

 This arrangement Focuses the sound waves at the entrance of the ear canal just like satellite dishes or spotlights focus radio waves or light.

  CAD methods have been employed to get the best out of the interference patterns created by more than one sound source radiating the same signal. The transient response of the K 280 parabolic has  been optimized using the Wigner distribution  (a mathematical model of sound) so high levels are no problem. This open-air design, being generously ventilated, conveys a sense of space and clarity of sound.
