The FD3 comes with a copper cable and 3.5mm plug; the FD3 Pro adds a silver-plated cable with swappable 2.5mm, 3.5mm and 4.4mm plugs. It is Hi-Res Audio certified and won a VGP 2024 Summer award.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-fd3-fd3-pro-in-ear-monitors-photo-hero.jpg?v=1791323664\" alt=\"FiiO FD3 in-ear monitors\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eA 12mm flagship-level DLC driver\u003c\/h3\u003e\n\u003cp\u003eFollowing its FD-series siblings, the FD3 uses a newly designed 12mm flagship-level dynamic driver. Its diamond-like carbon diaphragm is impressively rigid, which reduces unwanted distortion, yet surprisingly light, for excellent transient response, low distortion and high sensitivity. A strong magnet with 1.5 tesla of flux and an ultra-fine copper-clad aluminium voice coil from Japan’s Daikoku give a powerful sound.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-fd3-fd3-pro-in-ear-monitors-photo-dlc.jpg?v=1791323669\" alt=\"The 12mm DLC diaphragm driver of the FiiO FD3\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-fd3-fd3-pro-in-ear-monitors-photo-driver.jpg?v=1791323673\" alt=\"The FiiO FD3 driver and its 1.5T magnet\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eThe FD5’s acoustic prism\u003c\/h3\u003e\n\u003cp\u003eThe acoustic prism used so effectively in the flagship FD5 sits at the front of the FD3’s cavity too.
