{"type":"firestarter.listing","listing":{"id":"lst_0Ny60s37","product_name":"TANGZU Tang Sancai Narrow Bore","category":"Eartips","description":"\n\nConical Structure Design\nThe Tang Sancai NarrowBore version features a completely new internal conical structure design, unlike the previous two versions. After repeated testing and modifications, this structure complements the Narrow Bore's characteristics, ensuring the precise path of sound waves at the speed of sound. Adjustments to the hardness and length of the tube have been made to optimize this. The Narrow Bore version also sports a unique double flange-like shape for deep insertion, differing in appearance from its predecessors.\n\n  \n\nSpecial Wall Texture Design\nThe unique pattern on the eartips serves a dual purpose: efficient pressure release and a secure, comfortable fit for extended listening sessions. This design ensures that the eartips stay securely in place while providing optimal comfort.\n\n  \n\nNARROW Bore Diameter\nThe diameter of the bore plays a crucial role in sound balance and performance. During the development process, extensive analysis, experiments, and tests were conducted to achieve the ideal sound target effect. The Narrow Bore version enhances low-frequency quality while maintaining sound clarity, providing a well-balanced listening experience.\n\n  \n\nMedical-Grade Hypoallergenic Material\nTang Sancai uses medical-grade silicon to minimize the chance of any allergic reactions. This ensures not only superior sound quality but also a safe and comfortable user experience. The soft touch of the material makes wearing the eartips a blissful experience, allowing you to forget they are even there.\n\n  \n\nOptimized Core Design\nThe Tang Sancai Narrow features a shorter core designed to optimize clarity and responsiveness of sound, while still retaining a thick core for resistance to transformation and increased durability. This ensures that the eartips deliver high-quality audio performance while being robust and long-lasting.\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/2_52f5725e-9af3-4146-bfac-c773ab1dc0b4.jpg?v=1770789342","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/f8227597b389e8f81c4289db7abb838.jpg?v=1719483992","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/62a81f975625740c396b88fdc547bdd.jpg?v=1719483992","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/77aaa087668e71fa2ab1feb05639402.jpg?v=1719483992","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/630178d65bb440ade5ef3b8d6451938.jpg?v=1719483992"],"price":12,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:46.026Z"},"share_url":"https://firestarter.network/l/lst_0Ny60s37","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
