FiiO FH19 (6 Balanced Armature + 2 Dynamic) Hybrid In-Ear Monitor

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 optimized 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 customized 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.

Titanium+7000 series aluminum construction
The FIIO FH19 features build quality worthy of a flagship, to which the titanium midframe contributes. Its luxurious feel and uniquely charming titanium color give off a high-end appearance. Being the part of the earphone that is most frequently touched, the midframe’s pure titanium metal’s rigidity and corrosion resistance thoroughly protect the rest of the earphone’s shell, making it resistant to everyday wear and tear, truly embodying the essence of a flagship product.

7000 series aluminum shell
The FIIO FH19 employs 7000 series aluminum, which ensures a durable and strong shell while reducing the weight of the earphones. Thanks to this aluminum, the FH19 still provides a comfortable wearing experience even with more drivers and a more complex acoustic design.

Unfatiguing listening, large soundstage Semi-open design
The semi-open design has been highly praised in the FIIO FH9, FH7S, FH5S, and FD5. In the FH19, this proven semi-open design is once again utilized and has been specially tuned to combine with FIIO’s front and rear cavity balanced pressure relief technology – resulting in and more natural and relaxed sound, with a wide soundstage. This design efficiently balances the internal air pressure, eliminating the feeling of pressure on the eardrum which also helps to protect your hearing. Enjoy listening for long periods without fatigue.

Focus on small details, achieving large upgrades Suspended voice coil
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.

Scalpel-like accuracy Rubycon audiophile-grade film capacitor crossovers
Crafted with meticulous attention to sound quality, the flagship FH19 features the same high-precision Japanese film crossover capacitors as the FA19 that exhibit exceptional accuracy in phase alignment. While conventional resistor-based crossover components typically have an accuracy error of around 1%, the FH19 achieves an impressively low error rate of 0.1%. Furthermore, compared to ordinary ceramic capacitors, the FH19 not only achieves more precise crossover points but also effectively enhances high-frequency resolution and overall results in a more detailed sound.

Four-way acoustic design
“While the basic design is derived from the FH9, the FH19 builds upon its predecessor and surpasses it by updating the low-frequency and mid-frequency drivers and implementing them into a more precisely controlled four-way crossover design. In the low frequencies, custom push-pull dual-dynamic driver units are employed, and a ‘turbine low-frequency boost technology’ is used for physical low-pass filtering for relaxed yet natural bass. For the mid-frequencies, FH19 introduces an innovative ‘3+1 semi-open’ acoustic layout of balanced armatures. This is complemented by a newly designed resonant cavity, allowing for two separately managed mid-frequency zones that result in richer and more emotionally engaging mids. For the high frequencies, the FH19 retains the coaxial design with an acoustic guide while also incorporating Rubycon audiophile-grade film capacitors. This combination allows for high resolution while maintaining excellent treble tone.”

Turbocharged energy, Patented S.Turbo design
Inspired by turbochargers found in supercars, the FIIO development team meticulously created the S.Turbo patented acoustic design. This design ingeniously leverages sound wave guidance properties, enhancing bass performance through a turbine-shaped structure. The result is deep and vibrant bass. Additionally, the design cleverly filters out excess mid-to-high-frequencies from the dynamic driver, ensuring smooth transitions between the low and mid-high frequencies. The result is a more powerful and robust sound.
