Second-generation self-developed 14.5mm in-ear planar driver| 1μm thin diaphragm | Titanium + Aluminum dual-coating patented technology 28 nm-grade process technology | 0.055mm ultra-fine traces | 14 N52 neodymium magnets on each unit “Tesla valve” patented bass enhancement acoustic technology | Lightweight 6.5g per unit | Specially designed for comfort Rosewood/Black walnut versions available | 4 strands totaling 392 wires of silver-plated copper cable | 3.5/4.4mm swappable plug

• 1μm Ultra-thin Coating: After two years of independent research and development, FiiO has achieved the leading 1μm ultra-thin diaphragm in its class, with the diaphragm material made of high-performance PET substrate. As a result, the FiiO FP3 has significant performance advantages, accurately reproducing ultra-high frequency nuances and providing you with outstanding dynamic range and frequency characteristics.
• Titanium + Aluminum Dual Coating Patent Technology: The diaphragm features a dual coating of aluminum and titanium to enhance frequency response across different bands and improve audio resolution, allowing you to fully appreciate the delicate sound quality of planar drivers. The aluminum layer is lightweight, effectively increasing voice coil conductivity, while the titanium layer, known for its high hardness, significantly enhances high-frequency resolution.
• Patented bass enhancement acoustic technology: Acoustic engineers have designed specific branch lengths, angles, and quantities inside the headphone cavity to create a Tesla valve fluid structure that aligns with acoustic design. This significantly enhances the headphones' ability to produce deep, elastic low frequencies, allowing you to truly experience rich, profound bass.
• Dual-sided 14 N52 magnet: We adopts the N52 magnet with the highest performance in the double-sided array type, which coupled with the excellent magnetic circuit structure, maximizes the effective magnetic flux, realizes the high sensitivity of the planar driver.
• 3D-printed front shell+ wood faceplate: The Fiio FP3 features a natural solid wood headphone cover, available in options of rosewood and walnut. As an in-ear planar headphone, each Fiio FP3 weighs only about 6.5g. The front cavity is made using high-precision 3D printing technology, allowing it to be shaped flexibly according to the contours of the ear. This reduces pressure on areas like the ear canal and auricle. Additionally, a specific support structure has been added in the concave area of the ear, enhancing both comfort and stability.
• 0.78mm 2-pin High-purity silver-plated copper cable: The use of a 4-strand, 392-core copper-silver alloy wire twisted in a Litz structure increases the conduction area, effectively enhancing the high-frequency resolution of the headphones.
