    Supercharged Bass
    With Patented S.Turbo design 

    The bass frequency sound tube features FiiO's patented S.Turbo acoustic technology, which cleverly guides sound waves through a turbine shaped tube to enhance bass frequencies. As a result, while the bass is deep and powerful without being bloated and muddy. At the same time, this design also filters redundant frequency sound from the other higher-frequency drivers, ensuring a smoother connection between the bass and mids. In a nutshell, S.Turbo will give you a supercharged listening experience you won't forget.

    Fatigue-free listening, semi-open acoustic design

    The FH9 features a semi-open acoustic design incorporating FiiO's system of balanced pressure relief between the front and rear cavities. The result is more natural sound, and more comfortable listening in longer sessions due to greatly minimized pressure on your eardrums when listening.

    Undesirable sibilance is often the result of driver units being placed into a shell with no consideration of how they interact with each other, making it more likely that unwanted resonances occur. Thus, using finite element analysis, FiiO specifically designed the FH9's shell to feature a notch filter which effectively eliminates unwanted resonances generated in the shell, sound tube, and cavity. The result is greatly minimized undesirable sibilance for a purer and more transparent sound. 

    Ultimate purity
    With unique notch filter 

    We provide two color schemes for the FH9, gray and black. The FH9’s next-generation industrial design gives it a decidedly premium look and feel worth of its status. Not only is the FH9’s titanium construction beautiful, but its extreme rigidity also helps to greatly minimize unwanted harmonics and resonances for better sound quality.

    Build quality worthy of a flagship

    pure titanium construction

    Each FH9 ear unit is precisely made with five-axis CNC machining to ensure it meets tight tolerances and be of high build quality. All of this is combined with a pleasing feel against your skin for excellent wearing comfort, allowing you to easily immerse yourself into long listening sessions.

     

    Flagship Hybrid IEM

    1 dynamic 6 BA driver acoustic design

    FiiO’s new flagship hybrid IEMs, the FH9, is the result of two years’ worth of intense research on how to fully take advantage of the strengths of hybrid IEMs and push the boundaries of what they can sound like. This 1 dynamic 6 BA driver design (7 in total) features a 2nd generation 13.6mm DLC diaphragm dynamic bass driver fully capable of extending to the lowest frequencies with ample punch. Mid and high frequencies are handled by a custom 6 Knowles BA setup that accurately reproduces every last musical detail. Together, these drivers provide a rich and detailed musical soundscape fully befitting a flagship.

     

    Specially customized

    6 Knowles BA setup

    All 6 BA drivers in each ear unit of the FH9 are from Knowles. High frequencies are handled by the proven SWFK-31736 driver. For the mid frequency drivers, FiiO has partnered with Knowles themselves in over 2 years of extensive research on how to best implement such drivers to achieve perfect harmony between multiple drivers for an absolutely coherent sound.

    The FH9s shell is specially engineered to eliminate unwanted harmonic resonance generated as sound waves travel through the shell, sound tube and cavity – which greatly eliminates undesirable sibilance in the sound.

    The FH9 is FiiOs first hybrid IEM to feature a self-developed 2nd generation DLC (diamond-like carbon) bass driver. Compared to the 1st generation driver, the magnetic circuit structure has been redesigned resulting in 20% higher magnetic density to better push the massive 13.6mm DLC diaphragm – which means an even more dynamic sound. And thanks to DLCs outstanding rigidity and high damping coefficient, the FH9s bass driver is capable of providing extremely quick transient response with extremely minimal distortion.

    "The advantage of multi-unit products is that they can extract the advantages of different units and combine them. FH9 not only uses large-size moving coil units, but also uses Lou's ultra-high frequency moving iron units. The frequency response coverage is very wide and the energy density is large. This is very important for the playback of small energy information; for example, the ultra-high frequency energy is small, but it is extremely important, there is no sense of space, so better resolution requires sufficient sound density. If the density is enough to hear the string, it will feel sticky, the wind will be thick and full, and the percussion instrument will feel air vibration when it is knocked. The instrument and the human voice will sound more stable, more solid, and more like real sounds."

    *The black sound filter comes pre-installed. Other filters are included as accessories.

    Parameters

    The beautiful stainless steel angled MMCX connectors are designed to make your wearing experience as painless as possible. Details such as the special angle allow you to more easily connect your IEMs for more comfortable wearing as well as the left blue right red indicators to quickly get you going. All serve to let you purely focus on enjoying your music.

    Materials with weak rigidity are slower to respond to voice coil movements and produce irregular ripple-like movements, causing distortion.

    Because of its use of rigid DLC material, the diaphragm is more responsive to voice coil movements for less distortion and more accurate reproduction of sound.

    Included with the FH9 is a high-purity pure silver cable with 8 branches of 28 wires each, for a total of 224 wires. Each wire is individually isolated and all are braided together in the Litz style. The outer sheath of the cable is made from environmentally friendly TPU, which not only sports a radiant transparent look but is also resistant against yellowing under long-term use and stiffening when in low-temperature environments.
