{"type":"firestarter.listing","listing":{"id":"lst_xiMoB-UX","product_name":"CrinEar Daybreak","category":"In-Ear Monitors","description":"\nScience-Backed Tuning Philosophy\nCrinEar Daybreak is the first mass-production model under Crinacle’s personal brand, built on years of measurement data and tuning refinement. Targeting the IEF Preference 2025 Curve, Daybreak offers speaker-like balance with natural mids, clean bass, and controlled treble. It's the definition of neutrality—engineered with precision, not guesswork.\n\n\n\n\nAdvanced Tribrid Driver Configuration\nEquipped with a custom 1DD+2BA+2mPT layout, Daybreak delivers full-spectrum resolution. A dynamic subwoofer ensures deep, tight low-end response. Two custom-tuned balanced armatures reproduce natural mids, while dual micro-planar tweeters extend the treble with ultra-fine clarity.\n\n\n\n\n\n3D-Printed Acoustic Engineering\nInside the fully-filled resin shell lies a complex, 3D-printed internal waveguide system. This architecture enables precise frequency separation and acoustic control, allowing every driver to perform at peak efficiency without phase or crossover distortion.\n\n\n\n\n\nBuilt for Long Listening Sessions\nThe ergonomic, pseudo-custom shell is designed for comfort and noise isolation. Lightweight and durable, the medical-grade resin construction pairs with an aluminum nozzle under 6mm for universal eartip compatibility—ideal for hours of fatigue-free use.\n\n\n\n\n\nModular Cable System Included\nBundled with a 4-core silver-plated copper cable featuring interchangeable 3.5mm SE and 4.4mm balanced plugs, Daybreak ensures optimal signal integrity and maximum convenience. Standard 0.78mm 2-pin connectors make future upgrades effortless.\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/CrinearDaybreak_2_1.jpg?v=1758854756","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/CrinearDaybreak_3_1.jpg?v=1758854756","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/CrinearDaybreak_4_1.jpg?v=1758854756","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/CrinearDaybreak_8_1.jpg?v=1758854811","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/CrinearDaybreak_9_1.jpg?v=1758854811","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/CrinearDaybreak_5_1.jpg?v=1758854811","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/CrinearDaybreak_1_1.jpg?v=1758854811"],"price":169.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:44.767Z"},"share_url":"https://firestarter.network/l/lst_xiMoB-UX","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
