Carefully tuned open-back acoustic structure
When playing back spatial sound sources with headphones, the sound field is virtually reproduced by performing signal processing at the source that considers HRTF for the spatial information of the sound source.
By adopting an open back acoustic structure that does not acoustically close the housing, the reflected sound inside the headphones is reduced, enabling more accurate sound field reproduction.
In addition, for optimal control of the airflow in front and back of the driver unit, acoustic resistors are used in as large an area as possible to eliminate spatial resonance.
This realizes natural and rich bass reproduction without colouring.
