Fine-tuned curve, outstanding frequency response through meticulous engineering 

"The advantage of hybrid driver products is the ability to draw on the strengths of different types of drivers and combine them. The FH9 not only utilizes large dynamic drivers, but also ultra-high frequency Knowles BA drivers. Together, these drivers work to cover a very wide frequency range and are capable of producing great energy in a dense package. These characteristics are crucial for reproducing even the tiniest of details at any frequency. For example, ultra-high frequencies are usually only a small part of actual music, but are extremely important to how we perceive the music. If your system cannot reproduce that tiny part of your music with sufficient resolution, you will get a dry, closed sound. So, you need to have a system capable of high resolution at any frequency with a 'dense' sound for true high-fidelity audio. With a 'dense' enough sound, string instruments will sound appropriately soft, wind instruments will sound duly full, percussion instruments will clearly portray them vibrating the air, and human voices will sound more solid – overall a more realistic sound.”

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.  

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. 

Hi-Res Audio certified

The FH9 is Hi-Res Audio certified, ensuring you can listen to your music with all of its rich details, as the artist intended.
