NEW FLAGSHIP FIIO FH19 IN EAR MONITORS ANNOUNCED

FiiO has announced a new IEM flagship hybrid design with custom-built drivers, the FiiO FH19 In Ear Monitors.

The FiiO FH19 In Ear Monitors have a two dynamic plus six balanced armature driver configuration.

FIIO FH19 IN EAR MONITORS

The new FiiO FH19 features a dual-dynamic and six balanced-armature driver configuration. FiiO’s Engineering Team has worked closely with Tokyo Onkyo Co. Ltd. in Japan to develop an all-new Push-pull Dual Dynamic Driver unit to handle the bass frequencies.

The mid-to-high frequencies within the FH19 are handled by specially customised Knowles enhanced midrange Balanced Armature (BA) drivers.

PUSH PULL DUAL DYNAMIC DRIVERS

The Push-pull Dual Dynamic Driver unit used in the FH19 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, this is designed to ensure 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.

SEMI-OPEN DESIGN

The FH19 adopts a semi-open design that has been specially tuned to combine with FiiO’s front and rear cavity balanced pressure relief technology .This design aims to efficiently balances the internal air pressure, eliminating the feeling of pressure on the eardrum, ensuring long periods of listening without fatigue.

TITANIUM MID-FRAME

The FH19’s mid-frame is made from a Titanium, and the shell fashioned from 7000 Series Aerospace Aluminium ensuring a strong, yet lightweight pair of IEMs.

SUSPENDED VOICE COIL

To achieve flagship-level driver performance, the FIIO FH19 utilises a suspended voice coil design, with voice coil leads routed directly from the centre hole beneath the diaphragm, allowing them to float within the gap. This approach was chosen as it eliminates unnecessary contact and avoids additional adhesive load.

FOUR-WAY ACOUSTIC DESIGN

FiiO’s engineers have designed the FH19 to use its low-frequency and mid-frequency drivers in a precisely controlled four-way crossover design. For 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 the mid-frequencies, the 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 high frequencies, the FH19 adopts a coaxial design with an acoustic guide, whilst also incorporating Rubycon Audiophile-grade Film Crossover Capacitors, the same as those found in FiiO’s FA19 BA IEMs.

S.TURBO PATENTED ACOUSTIC DESIGN

FiiO’s patented S. Turbo design ingeniously leverages sound wave guidance properties, enhancing bass performance through a turbine-shaped structure.  Additionally, the design cleverly filters out excess mid-to-high-frequencies from the FH19’s dynamic drivers.

FIIO FH19 SWAPPABLE AUDIO FILTERS

The FH19 comes with three pairs of swappable audio filters. Each filter has different internal damping and mesh density, allowing you to adjust the sound profile of the FH19, according to your personal preference:

Red audio filter. Enhances low frequencies, providing powerful and impactful bass

Black audio filter. Offers balanced sound that is clear and transparent

Green audio filter. Delivers refined and detailed treble

FIIO FH19 IN EAR MONITORS CABLE-EAR TIPS AND MORE

The FH19 comes supplied with a high-purity pure silver cable, consisting of 8 strands of 28 wires each for a total of 224 wires. Each individual wire is independently insulated, and the cable is twisted using a Litz structure. The cable sheath is made from transparent TPU; effectively preventing yellowing due to prolonged use and stiffening of the cable due to use in low-temperature environments.

The FiiO FH19 comes with two twist-lock swappable jack plugs — 1 x 3.5mm single-ended, and 1 x 4.4mm balanced — ensuring the IEMs can be used with a wide range of audio devices including, Digital Audio Players (DAPs), Headphone Amplifiers, PCs and more.

In addition, to ensure the best fit and listening experience, the FH19 are supplied with 22 pairs of ear tips  including SpinFit, Foam, Balanced, and Dual Flange, in a variety of different sizes.
