4. What are the characteristics of the FH19 driver and sound performance?

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 Co. Ltd..

This technology employs two 13mm 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 suppresses any residual sound after the audio signal stops.

The mid-to-high frequencies are handled by six Knowles balanced armature drivers units. In order to achieve even higher levels of vocal sound quality, FiiO 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.

The most outstanding feature of FH19 sound performance is balanced, durable, which belongs to the type of long-listening without getting tired. Low-frequency clean, dense and mellow mid-frequency, high-frequency balanced and durable. Taking the advantage of the energetic dynamics, wide soundstage , no matter listening to pop music or large-venue classical music, FH9 can handle with ease.
