Description
Designed for listeners who want audiophile-grade sound without breaking the bank, the FiiO FD3 delivers a remarkably spacious and natural listening experience through its semi-open acoustic design. The 12mm Diamond-Like Carbon (DLC) diaphragm dynamic driver, paired with a 1.5 Tesla magnetic circuit and Japanese Daikoku voice coil, produces detailed, low-distortion audio with a frequency response reaching 40kHz.
Crafted from lightweight aluminum-magnesium alloy with a 2.5D film-coated glass faceplate, the FD3 weighs just 7 grams per earbud for all-day comfort. Its flagship-grade acoustic prism technology minimizes high-frequency standing waves and improves sound wave diffusion, while the patented balanced air pressure design reduces eardrum fatigue during extended sessions. The included interchangeable sound tubes let you dial in your preferred tuning — the black tube emphasizes treble detail, while the red tube delivers a warmer, bass-forward presentation.
Hi-Res Audio certified and equipped with a detachable MMCX cable made from high-purity monocrystalline copper, the FD3 is ready for any source, from smartphones to dedicated DAPs.
