{"type":"firestarter.listing","listing":{"id":"lst__Xs1iVig","product_name":"U18s","category":"Universal","description":"  \n64 Audio revolutionized the IEM industry in 2016 with its world class reference level U18t, the world's first 18-driver earphone. Now, with the introduction of U18s, 64 Audio has taken the heritage of the 18 driver platform and further pushed the envelope of innovation in sound and design. U18s combines proprietary drivers, LID technology and a new electronic crossover network to deliver a uniquely exceptional listening experience. \nU18s is handcrafted in the USA from aerospace-grade aluminum billet. CNC milled, sand blasted, fly cut, and twice anodized - the result is a striking fractal design that is inspired by nature itself.\n  ","images":["https://cdn.shopify.com/s/files/1/0411/4717/0966/files/PLP-Template.jpg?v=1782754977","https://cdn.shopify.com/s/files/1/0411/4717/0966/products/U18s-Angled.jpg?v=1670885657","https://cdn.shopify.com/s/files/1/0411/4717/0966/products/U18s-Back.jpg?v=1670885657","https://cdn.shopify.com/s/files/1/0411/4717/0966/files/U18s-Included-Flat-Lay.jpg?v=1782768596"],"price":2999,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:54:58.760Z"},"share_url":"https://firestarter.network/l/lst__Xs1iVig","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
