Facing problems head-on, Breaking through them
The FP3 is equipped with FIIO’s second generation, self-developed 14.5mm in-ear planar driver. The planar driver has been designed from the ground-up by FIIO, from the diaphragm, to the patented dual-coating, to the conductive trace width, to the fine-tuning of the magnetic circuit, and even the standardized bracket fixings. Compared to typical off-the-shelf drivers, the self-developed driver can be completely customized to build and fit around it a sophisticated acoustic system, allowing the driver to achieve significant breakthroughs in sound quality.
Thanks to this intensive research and development, the FIIO FP3 features a large, almost limitless soundstage rarely found among its peers. It also effortlessly produces deep bass and detailed treble up to 40kHz, allowing you to fully dive into the music.
Dual-sided 14 N52 neodymium magnets
In order to achieve a comfortable and lightweight design, the development team decided to place 7 N52 high-performance neodymium magnets on both sides of the FP3’s driver. These magnets are arranged in a 7×2 pattern, totaling 14 in all. The balanced placement of these magnets allows the dual-coated traces to be distributed evenly within the magnetic field. This completes a matrix-style magnetic circuit system, ensuring that the diaphragm experiences balanced forces on both sides. As a result, the diaphragm does not move in irregular ways, which reduces distortion, and achieves high-fidelity sound.
A true standout, 1μm ultra-thin diaphragm
Engineers have constantly strived to achieve thinner and lighter diaphragms for planar drivers. After two years of independent research and development, we have created a class-leading 1μm ultra-thin diaphragm, using high-performance PET as the substrate. The difference between even a 2μm and a 1μm diaphragm thickness results in noticeable performance differences when the diaphragm is vibrating at high speeds, which ultimately affects sound quality.
The FP3’s 1μm ultra-thin diaphragm is exceptionally lightweight, allowing it to respond with lightning-quick speed. It faithfully reproduces even subtle sounds in the ultra-high frequency range, as well as providing exceptional dynamic range.
Dual-stacked, Finely-tuned frequency response
The FIIO FP3 employs a newly self-developed technology for its planar driver – a patented dual-coating system. The planar driver uses high-performance PET as the diaphragm substrate and selectively applies aluminum and titanium to create a dual-coated driver. Such a design enhances the driver’s frequency response across different frequency ranges, improves audio resolution, and allows listeners to fully appreciate the nuanced sound quality of planar drivers.
The first coating layer is made of aluminum. Lightweight and conducive, the aluminum coating enhances the traces’ conductivity, helping to reduce the IEM’s impedance and power requirements.
The second coating layer is made of titanium. With its high hardness, the titanium coating contributes to the diaphragm’s rigidity and enhances treble resolution and overall transparency.

“Tesla valve” patented bass enhancement acoustic technology
The FIIO FP3 is equipped with the same F.T.B.S.* “Tesla Valve” patented bass enhancement acoustic technology as in the FD15. The lengths, angles, and quantities of channels within the IEM’s cavity have been specially calculated to achieve a Tesla valve fluid structure. The result is significantly enhanced and deeply extended yet textured bass.
