A 10.3mm dual-cavity driver with a beryllium-plated bio-cellulose diaphragm sits in mirror-polished 316 stainless steel shells, and a custom cable with OCC copper and silver-plated cores completes it. At 37Ω and 108dB it runs happily from a phone, and shines with a hi-res player.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/cayin-yd01-fantasy-beryllium-plated-single-dynamic-iem-photo-hero.jpg?v=1791377321\" alt=\"Cayin Fantasy single dynamic driver in-ear monitor\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eShaped to touch your heart\u003c\/h3\u003e\n\u003cp\u003eThe design is elegantly inspired by stringed musical instruments, combining lines and curves to pair strength with gentleness.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/cayin-yd01-fantasy-beryllium-plated-single-dynamic-iem-photo-shape.jpg?v=1791377326\" alt=\"Cayin Fantasy, inspired by stringed instruments\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eDual cavity, two-way magnetic structure\u003c\/h3\u003e\n\u003cp\u003eAn additional rear cavity lets the sound wave flow smoothly and reduces resonance, for more clarity and a more holographic soundstage.
