{"type":"firestarter.listing","listing":{"id":"lst_OgrMsbyt","product_name":"DUNU Mortise","category":"Headphones","description":"\n  \n    Immersive Natural Soundstage\n    Crafted for listeners who value the essence of sound, the DUNU Mortise delivers a warm, rich, and full-bodied audio experience. Vocals are textured and cohesive, low frequencies are deep and controlled, while treble extends smoothly without harshness or sibilance. Its spacious, well-layered sound remains fatigue-free across long listening sessions, excelling in pop, vocal, and instrumental genres.\n  \n\n  \n    Open-Back Acoustic Architecture\n    The open-back design minimizes internal reflections and standing wave interference, allowing sound to propagate naturally. This enhances soundstage width and depth, providing precise imaging and an immersive, well-balanced listening experience that is comfortable for extended use.\n  \n\n  \n    Ultra-Thin Carbon Fiber Dynamic Driver\n    Featuring a 50mm full-range driver with an N52 neodymium high-flux magnetic circuit, the ultra-thin carbon fiber diaphragm ensures stable, linear performance. The W-shaped diaphragm profile and flexible surround system minimize distortion while enhancing detail retrieval and resolution across the frequency spectrum.\n  \n\n\n  \n    Adaptive Ergonomic Structure\n    The adaptive suspension headband conforms naturally to different head shapes, evenly distributing pressure for a secure yet relaxed fit. Soft, high-resilience memory foam ear cushions maintain acoustic integrity while providing long-term comfort.\n  \n\n  \n    High-Purity Single-Crystal Copper Cable\n    The detachable cable ensures optimized signal integrity and minimal interference. The Q-Lock Mini interchangeable plug system includes 3.5mm single-ended and 4.4mm balanced terminations, plus a 3.5mm to 6.35mm adapter, offering broad compatibility and future-proof flexibility.\n  \n\n\n  \n    Premium Carrying Case\n    A custom fabric carrying case is included, providing refined protection for your headphones and accessories.\n  \n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/2_cc5aff25-d46b-4f3a-b274-dfefffaff3b1.png?v=1775645132","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/1_6_f00d5dcb-8aaa-44bf-9453-8a66d5952b28.jpg?v=1775645132","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/1_1_cc7ee824-ecf7-4ebc-9220-8ace0242b9cb.jpg?v=1775645132","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/DSC01148.jpg?v=1775645132"],"price":429.9,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:44.096Z"},"share_url":"https://firestarter.network/l/lst_OgrMsbyt","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
