{"product_id":"fiio-ff5-flat-head-dynamic-driver-earbud","title":"FiiO FF5 Flat-Head Dynamic Driver Earbud","description":"\u003cp\u003eThe FiiO FF5 is a flat-head earbud, the classic open style that rests in the outer ear rather than sealing the ear canal, rethought with a large 14.2mm dynamic driver and a carbon-based diaphragm. FiiO tuned it especially for female vocals, with a diffuse open back and acoustic resistance pipes for cleaner, more extended bass than earbuds usually manage. The CNC aluminium shells weigh just 3.4g, and unusually for an earbud the cable detaches, with swappable 3.5mm and 4.4mm balanced plugs.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-ff5-flat-head-dynamic-driver-earbud-photo-hero.jpg?v=1791322903\" alt=\"FiiO FF5 flat-head earbuds with their cable\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eTuned for female vocals\u003c\/h3\u003e\n\u003cp\u003eAs Joseph, chief engineer of FiiO’s IEM R\u0026amp;D centre, explains: the female voice spans roughly 160Hz to 1.2kHz, and the FF5 was designed to focus on it rather than on heavy bass. The team controlled the resonance at 127Hz so vocals don’t sound muddy or boomy, and lifted 2kHz–4kHz slightly to make female voices clearer, more transparent and more prominent. The light carbon diaphragm gives excellent treble, so the overtones of voices, guitars, cymbals and violins come through with nuance and layering.\u003c\/p\u003e\n\u003ch3\u003eA large 14.2mm carbon-based driver\u003c\/h3\u003e\n\u003cp\u003eBreaking with earbud tradition, the FF5 uses a specially developed 14.2mm dynamic driver with a carbon-based diaphragm and a PU surround, both light and very rigid. Unwanted movement is kept in check, minimising non-linear distortion, for quick transients and excellent treble resolution.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-ff5-flat-head-dynamic-driver-earbud-photo-driver.jpg?v=1791322909\" alt=\"The 14.2mm carbon-based dynamic driver of the FiiO FF5\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eA diffuse open back, like a flower in bloom\u003c\/h3\u003e\n\u003cp\u003eInspired by the layers of a flower’s petals, the FF5’s diffuse open design uses an acoustic damping device that lets some of the air pressure inside the earbud escape. That reduces internal reflections and standing waves, for a purer sound and better bass.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-ff5-flat-head-dynamic-driver-earbud-photo-diffuse.jpg?v=1791322912\" alt=\"Airflow through the diffuse open back of the FiiO FF5\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eAcoustic resistance pipes for extended bass\u003c\/h3\u003e\n\u003cp\u003eEarbuds need more care than in-ear monitors to sound great, and after much experimentation FiiO developed acoustic resistance pipes for the FF5. As the diaphragm moves, the air pressure is diverted into the pipes, reducing low-frequency resonance, so the bass is more extended and better textured.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-ff5-flat-head-dynamic-driver-earbud-photo-cutaway.jpg?v=1791322917\" alt=\"Cutaway of the FiiO FF5 showing the driver and acoustic pipe\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eLight aluminium, with anti-slip rings\u003c\/h3\u003e\n\u003cp\u003eThe shells are aluminium alloy, as used in many high-end earphones, light yet durable: each earbud weighs only about 3.4g, so it almost disappears in your ear. Some listeners prefer silicone rings on earbuds, so as well as three types of foam cover, FiiO includes six moulded anti-slip silicone rings in two sizes. They give a better seal for more extended bass while keeping the resolution elsewhere.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-ff5-flat-head-dynamic-driver-earbud-photo-rings.jpg?v=1791322920\" alt=\"The anti-slip silicone rings included with the FiiO FF5\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eA 392-wire cable you can detach\u003c\/h3\u003e\n\u003cp\u003eFew earbuds have detachable cables, which makes them hard to keep using if the cable fails. The FF5 uses expanded MMCX connectors, so you can replace the cable or try others. The included cable is high-purity silver-plated monocrystalline copper: 14 wires braided into a small strand, seven small strands into a large one, and four large strands in all, 392 wires. The extra cross-section and Litz braiding improve conductivity and treble resolution.
