In order to achieve a level of sound quality that was not possible at this price, the Final Audio A4000 began with the establishment of a new development and production site. 6mmΦ dynamic drivers were designed entirely new, including not only the components but also the production equipment.

The sound quality was designed based on final's original evaluation method established during the development of the flagship A8000 earphones. The new earphones deliver what we call "transparent sound," the impression of sound that can be heard clearly even when sound is localized at a distance, across a wide range of music.
