FiiO FH19 HiFi Earphone 2 Dynamic 6 Balanced Armature Drivers IEMs

The FiiO FH19 is equipped with a push-pull dual dynamic driver unit, utilizing high-end push-pull audio technology. It consists of two active dynamic driver units that work in a "push-pull" manner. On a microscopic level, when one dynamic driver diaphragm "pushes" butward, the other diaphragm "pulls" inward, and vice versa. On a macroscopic level, the two dynamic driver units can be seen as a single entity, moving in the same direction, providing double the driving force and phase consistency.

The FiiO FH19 uses six Knowles balanced armature drivers as its mid and high-frequency sound units. In order to achieve even higher levels of vocal sound quality, FILO collaborated with Knowles to create a custom mid-frequency-enhanced balanced armature driver. By adding acoustic vents to the rear cavity of the driver, the mid-frequency driver gains more sound energy compared to typical mid-frequency drivers. This further unlocks the inherent advantages of the mid-frequency driver, resulting in rich and mellow vocals that are hauntingly realistic, as if the singer was right next to you.

To achieve flagship-level driver performance, the FiiO FH19 utilizes a suspended voice coil design. In this design, the voice coil leads are routed directly from the center hole beneath the diaphragm, allowing them to float within the gap. This approach eliminates unnecessary contact and avoids additional adhesive load. Compared to conventional diaphragms*, the suspended voice coil design ensures uniform and smooth diaphragm movement, minimizing interference from other factors and fully unleashing the inherent potential of the diaphragm.
