{"type":"firestarter.listing","listing":{"id":"lst_B3VzUJD6","product_name":"FiiO FT13","category":"Headphones","description":"\n\nPurpleheart Craftsmanship, Pure Acoustic Beauty\nThe FT13 continues FIIO’s pursuit of wooden headphone artistry after the acclaimed FT1. Crafted from Purpleheart wood sourced from South America’s ancient rainforests, the ear cups are naturally oxidized over 90 days to achieve a deep, wine-like purple hue. Each cup is unique, combining exotic aesthetics with excellent acoustic damping to reduce resonance and enhance sonic purity. Symbolizing rarity, strength, and individuality, the Purpleheart wood reflects FIIO’s dedication to merging natural beauty with acoustic precision.\n\n\nDeep, Immersive Sound with 60mm Dynamic Driver\nEquipped with a 60mm large dynamic driver, the FT13 delivers extended bass depth, expansive soundstage, and reduced distortion. The driver ensures powerful dynamics and precise transient response, making every note impactful while preserving detail across the frequency range.\n\n\nWool-Composite Nanofiber Diaphragm\nThe diaphragm is crafted from European birch pulp using a century-old papermaking technique. Blended with wool fibers and reinforced with carbon fibers, it achieves exceptional rigidity, reduced breakup vibrations, and enhanced treble resolution. The result is a diaphragm only 0.1mm thick—lightweight, natural-sounding, and highly expressive.\n\n\nW-Shaped Diaphragm for Enhanced Efficiency\nInspired by loudspeaker paper cones, the W-shaped diaphragm increases effective vibrating area by 25.8%. With a rigid dome and soft suspension, it reduces distortion while maximizing efficiency, offering cleaner mids and highs with remarkable clarity.\n\n\nClosed-Back Acoustic Design for Noise Isolation\nThe FT13 features a closed-back architecture with passive noise reduction, achieving up to -26dB isolation. A specially engineered U-shaped acoustic tube, wave-dissipation chambers, and damping cotton further reduce external noise and resonance. Ideal for commuting, office, or late-night listening, the design ensures immersive sound without disturbing others.\n\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/FT13_343e48b5-dae3-4b33-b171-2d70c60b0edb.png?v=1772611480","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/FT13_f52593c8-8bef-4638-af50-da644dbcae58.jpg?v=1772611480","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/FT13.png?v=1772611480","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/FT13_3137f98d-9a07-452a-9228-364547717eff.jpg?v=1772611480","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/FT13_e794c736-83f3-427a-940a-e0cead0ef9f8.jpg?v=1772611480","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/FT13.jpg?v=1772611480"],"price":349.45,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:44.201Z"},"share_url":"https://firestarter.network/l/lst_B3VzUJD6","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
