{"type":"firestarter.listing","listing":{"id":"lst_ZHtWyWhT","product_name":"Yanyin Canon II","category":"Earphones/IEMs","description":"\n\n\n\nThe Perennial Paradigm of the Yanyin Atelie\nCanon as Yanyin Studio's longest-running product line, has very distinctive features, and has been recognized by many users. This Canon II is also a chic product with some new features in addition to the original excellent design, such as such as the latest bio-dynamic driver, Galaxy-looking faceplate and graphene single crystal copper silver-plated cable.\n\n \n\n\n\nClassical, Yet Not Outdated, Structure\nThe Canon II perpetuates the quintessential \"1DD+4BD\" configuration. The \"1DD\" employs a third-generation bio-diaphragm Dynamic Driver, accompanied by a dual-chamber spatial design, which optimizes air pressure balance, thereby enhancing low-frequency dynamism and facilitating deeper immersion. Consequently, an audiophile-grade low-frequency experience is attainable even with earphones. The \"4BD\" comprises two full-size Balanced Armature drivers for mid-to-high frequencies and an additional two for high frequencies, resulting in a harmonious sound density across these ranges, ensuring outstanding audio quality.\n\n \n\n\n\nHigh-Quality Cable to Attenuate Stethoscope Effect\nThe Canon II’s auricular cabling utilizes four strands of graphene single-crystal copper plated with silver. The cabling has a supple texture to mitigate the stethoscope effect and is supplied with customizable plugs and jacks that can be freely paired.\n\n \n\n\n\nPhysical Acoustic Conduit, Multiple Tuning Modalities\nCanon II includes two independently controllable low-frequency switches, affording four tuning modes. Furthermore, the exterior boasts a medical-grade resin with a handcrafted shell, surpassing the durability and eco-friendliness of 3D-printed alternatives.\n\n\n\n\n\n\n\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9734.jpg?v=1685344396","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9722_d7bd7c39-db91-4b63-8c30-12e7949f0175.jpg?v=1685344396","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9718.jpg?v=1685344396","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9673.jpg?v=1685344396","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9677.jpg?v=1685344396","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9693.jpg?v=1685344396","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9712.jpg?v=1685344396","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9700.jpg?v=1685344396","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9743.jpg?v=1685344396","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9715.jpg?v=1685344396","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9745.jpg?v=1685344396","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_9661.jpg?v=1685344396"],"price":379,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:46.997Z"},"share_url":"https://firestarter.network/l/lst_ZHtWyWhT","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
