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.

Build quality worthy of a flagship Titanium alloy construction

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 alloy construction beautiful, but its extreme rigidity also helps to greatly minimize unwanted harmonics and resonances for better sound quality. 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.

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 FH9's 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.

2nd generation FiiO DLC diaphragm dynamic bass driver

The FH9 is Fiio's 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 DLC's outstanding rigidity and high damping coefficient, the FH9's bass driver is capable of providing extremely quick transient response with extremely minimal distortion.

Fatigue-free listening Semi-open acoustic design

The FH9 features a semi-open acoustic design incorporating FiiO's patented 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.

Specially-tuned sound interchangeable sound filters

The flagship FH9 comes standard with three interchangeable sound filters. Each sound filter has its own damping and filter density, allowing you to choose between three different sound signatures.

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

RED: Enhanced dynamic bass focus
GREEN: Clear, transparent balanced timbre
BLACK: Highly resolving detailed treble focus

Enhanced ergonomics Stainless steel angled MMCX connectors

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.

Pristinely pure High-quality high-purity pure silver cable

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.
