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.
