Balancing high-resolution, clear vocals with powerful bass
Generally speaking, most wireless earphones rely heavily on a software based equalizer for sound quality adjustment, particularly for sound emanating from the high range, and this is a cause of listening fatigue. Moreover, bass is overemphasized in an effort to avoid this phenomenon, resulting in the current situation in which many competing products do not achieve balance. Having pursued acoustic characteristics for the driver, etc. so as to make it possible to achieve satisfactory sound even without the use of a software-based equalizer, we have adopted a methodology for equalization to achieve a slight correction of just the irritating high range sound caused by Bluetooth®. With the backing of this technology we achieve good sound reproduction that strikes a balance between high-resolution, clear vocals and powerful bass.
