In a typical listening room, sound from speakers you perceive consists of three elements: direct sound, early reflections (echoes from walls/ceiling/floor), and reverberation. These elements let you locate the sound source and recognize its size. This is called Head Related Transfer Function (HRTF).

In developing the 3D Headphone technology, JVC has applied an exclusive algorithm that divides the audio signals into the same three elements and conducts processing individually (convolution processing). This ensures that sound from headphones has the same realism, dynamism, and localization as that from multi-channel speakers.
