FORGING AHEAD FROM THE PAST - FLAGSHIP SOUND

Three years ago, the FH9 was launched, as FiiO’s first high-end flagship hybrid earphone. With its energetic dynamics, wide soundstage, and pleasant sound quality, it was enthusiastically received by HiFi users worldwide upon release. It gradually became known among audiophiles as a great example of “balanced earphones,” far exceeding our expectations in popularity. It is still a competitive set of earphones even in today’s market.

The new FiiO FH19 from FiiO is a significant upgrade, incorporating much user feedback. It retains the signature sound and flagship-grade craftsmanship of the FH9, and is also co-developed with Tokyo Onkyo Ltd. in Japan and Knowles in the USA. It features a truly high-end acoustic design, with richer and fuller midrange and more robust yet flexible bass. Additionally, the fit has been redesigned and optimised based on the characteristics of the human ear, allowing you to experience truly flagship-level comfort.

THE PINNACLE, FURTHER IMPROVED - TWO DYNAMIC SIX BA DRIVER CONFIGURATION

The new FiiO FH19 features a flagship-worthy dual dynamic and six balanced armature driver configuration. Handling the bass is an all-new push-pull dual dynamic driver unit co-developed with Tokyo Onkyo Ltd. in Japan. This driver features greatly enhanced low-frequency extension, cohesion, and speed. The mid-to-high frequencies are handled by specially customised Knowles enhanced midrange balanced armature drivers, which achieve greater sound energy density for rich and delicate vocals that are wonderfully musical without sacrificing detail.

POWERFUL COMBO - PUSH-PULL DUAL DYNAMIC DRIVER UNIT

FiiO, in collaboration with Tokyo Onkyo Co. Ltd., has developed a push-pull dual dynamic driver unit* for the FH19, based on push-pull technology used in high-end audio. This technology employs two 13.7mm high-magnetic dynamic drivers with PU+DLC composite diaphragms, arranged in an opposing configuration. When the diaphragms move back and forth, the overall movement direction of the two dynamic drivers remains consistent, ensuring phase consistency. This effectively doubles the driving force, and the diaphragms can provide air damping to each other. This makes the dynamic drivers exhibit more stable movement and fully suppress any residual sound after the audio signal stops.

Compared to typical dynamic drivers, push-pull dual dynamic drivers require only half the amplitude to achieve the target sound pressure level. This results in smaller diaphragm displacement, significantly improving linear driving performance and further reducing intermodulation distortion, allowing the driver unit to deliver cleaner sound.

*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” outward, 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.
