FiiO has officially launched the FX25 Hi-Fi earphones on Tmall, priced at ¥4 999. The device features a lightweight carbon fiber housing, with each earbud weighing approximately 7 grams. It is equipped with a standard 0.78mm 2-pin connector, allowing users to swap cables as needed.
Each earbud houses a hybrid driver configuration consisting of one 10mm lithium-magnesium alloy dynamic driver, two Knowles balanced armature units, and four Sonion electrostatic drivers. This setup covers a frequency response range of 10Hz to 40kHz.
The internal design incorporates the patented S.Turbo acoustic structure to boost low-frequency output and filter out unwanted mid-to-high frequencies. Additionally, an RLC second-order band-stop filter circuit is used to smooth out high-frequency resonance peaks.
The package includes a 1.2-meter liquid nitrogen-frozen 6N monocrystalline silver-plated copper cable with swappable plugs. The earphones have an impedance of 20 ohms at 1kHz and a sensitivity of 106dB per mW at 1kHz, along with a selection of silicone ear tips.
