Pure silver data lines consist of two independently insulated twisted pairs wrapped in gold-plated shielding, providing excellent bending performance without compromising flexibility.\n\n\nDirectional Connection\nWhen outputting USB audio signals, the system identifies an OTG device by detecting the resistor inside the USB-C plug. Correct plug orientation ensures proper signal flow when connecting USB DACs or players, optimizing playback accuracy.\n\n\nCNC Full-Metal Shielded Plug\nThe plug housing is crafted from aviation-grade aluminum via CNC machining. The three-piece assembly fully shields the soldered area, and the redesigned USB-C PCB reduces the overall profile compared with TC09L plugs, ensuring stable, interference-free signal transmission.\n\n\nStepped Non-Slip Ergonomic Design\nThe plug features a textured stepped structure that prevents slipping when pinched, making plugging and unplugging easier and smoother.\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TC19LL-01.jpg?v=1775128536","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TC19LL-02.jpg?v=1775128536","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TC19LL-04.jpg?v=1775128536","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TC19LL-05.jpg?v=1775128536","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TC19LL-06.jpg?v=1775128536"],"price":82.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:44.112Z"},"share_url":"https://firestarter.network/l/lst_FKuuE7JN","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
