4 years of fine tuning Forging ahead with the new reference grade hybrid

In 2018, FiiO implemented cutting-edge technologies such as the Trishell chassis, the S.Turbo acoustic design, and a 10-mm polymer composite driver in the FH5, which gave listeners a rich detailed listening experience. After the launch of the FH5, it was widely praised by users for its excellent deep bass and high resolving ability in an affordable package. It has been on the market for more than 50 months and is a testament to our dedication to great sound.

For 4 years and 3 generations of product launches of the FH5, we found that users wanted a brighter sound and even higher treble resolution but still maintaining some of the FH5 sound while being enjoyable for all kinds of music. Therefore, when designing the FH15 took the sound of the FHS as a Reference for tuning and developing the drivers in the FH15.

The lower frequencies are handled by an all-new 40mm dynamic driver with carbon-based diaphragm. The mid frequencies are produced by a custom Knowles ED BA driver, while the treble falls to the Knowles RAD for greatly improved transparency in the sound.

The bass, mids, and treble have been tuned in a way that allows the FH15 to sound great with all genres of music. For those wanting to precisely dial in the sound of instrumental music focusing on particular instruments such as the piano, guitar, violin, etc. the FH15 features interchangeable filters with distinctly different sounds.
