Flagship Hybrid IEM 1 dynamic 6 BA driver acoustic design
FiiO's 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 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.

Ultimate purity With unique notch filter
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.
