{"type":"firestarter.listing","listing":{"id":"lst_U6eRI3Lc","product_name":"Kefine Klean","category":"Earphones/IEMs","description":"\n\n\nSuperior Sound Quality with DLC Technology\nThe Kefine Klean earphones utilize a state-of-the-art 10mm dynamic driver featuring a diaphragm made from diamond-like carbon (DLC). This advanced material not only ensures remarkable clarity and detail but also extends high frequencies, providing a transparent and clean sound signature. The natural and musical audio profile includes powerful bass, warm mids, and smooth treble.\n\n\n\n\nRobust and Durable Construction\nCrafted with an alloy casting housing, the Klean earphones ensure consistent sound quality and stability. The durable build is reinforced with a screw design that prevents damage from adhesive failure or external force, promoting longevity. Polishing after casting provides a smooth and refined finish, enhancing the overall aesthetic appeal.\n\n\nComfortable Ergonomic Fit\nDesigned to contour to the human ear, the Klean earphones provide exceptional comfort for extended wear, ensuring a snug fit that enhances the listening experience.\n\n\nHigh-Quality Silver-Plated Cable\nEquipped with a high-purity silver-plated copper wire, the Klean cable features 18 strands per core for a total of 108 wires, promoting a clean and transparent audio signal. This robust cable design facilitates wide compatibility with aftermarket options through a 0.78mm 2-pin detachable connector.\n\n\nVersatile Tuning with Interchangeable Nozzles\nKlean earphones come with two interchangeable nozzles, each designed with distinct tuning systems to cater to different sound preferences. The silver nozzle offers a warm, smooth sound, while the black nozzle delivers a higher resolution with brighter, more transparent tones. This feature enhances versatility and allows users to easily adjust their listening experience. The threaded design makes swapping nozzles quick and convenient.\n\n\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/Kefine_Klean_SV_02.jpg?v=1770364299","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/2_0c329606-6b96-47a1-86a0-d131cd12cf21.jpg?v=1770364299","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/Kefine_Klean_SV_09.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KefineKlean-3.5_84fed725-5453-407e-ba5c-69f406c304a4.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/Kefine_Klean_SV_07.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/3_e5b42325-7558-424f-98ff-519465502bcb.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/5_341a7bd1-5c35-4224-b944-253c9a32e9e4.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/6_fbd14381-7df0-4fa7-b003-854a1fe4c936.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/16_89135e6a-a723-4437-bf71-81cdbc881395.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KefineKlean-USBC-Mic.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KefinetypeCcable_1.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KefineUSBC_mic_volumecontrolcable_5.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KefinetypeCcable_2.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KefinetypeCcable_4.jpg?v=1770022042","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/Kefine_Klean_SV_10.jpg?v=1770022042"],"price":59.99,"currency":"USD","in_stock":true,"inventory_qty":49995,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:45.718Z"},"share_url":"https://firestarter.network/l/lst_U6eRI3Lc","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
