{"type":"firestarter.listing","listing":{"id":"lst_8e8PQYbk","product_name":"CrinEar Reference","category":"In-Ear Monitors","description":"\n  \n    Purpose-Driven Design for Absolute Neutrality\n    The CrinEar Reference is engineered with a singular goal: achieving true reference-grade neutrality. Designed around a population-averaged diffuse field response tilted at -1dB per octave, it incorporates a subtle bass lift to maintain perceptual balance—compensating for real-world listening conditions and the physicality of low frequencies. Fully verified under ITU-T Type 4.3 conditions, the Reference represents a milestone in acoustic accuracy—delivering what can be considered one of the flattest in-ear monitor tunings ever achieved.\n  \n  \n\n  \n    World’s Flattest In-Ear Monitor Tuning\n    Through precise acoustic modeling and measurement validation, the CrinEar Reference achieves an exceptionally flat frequency response. This ensures that music is reproduced exactly as intended—without coloration, exaggeration, or masking of details. Whether for critical listening, mixing, or mastering, the Reference offers a transparent window into your audio.\n  \n\n  \n    Hybrid Driver System for Precision Performance\n    The CrinEar Reference features a sophisticated hybrid driver configuration combining dual dynamic drivers and balanced armatures. Two 10mm dynamic drivers handle sub-bass with authority and realism, while Sonion balanced armatures reproduce accurate mids, and a Knowles super tweeter delivers extended, detailed highs. This multi-driver system ensures full-range performance with excellent separation, resolution, and coherence.\n  \n  \n\n  \n    Precision-Machined Full Aluminum Housing\n    Crafted using 5-axis CNC machining, the full aluminum shell offers exceptional structural rigidity and durability. This minimizes unwanted resonance and enhances acoustic stability, ensuring consistent and accurate sound reproduction.\n  \n\n  \n    Engineered for Audiophiles and Professionals\n    Designed in Singapore, the CrinEar Reference is built for audiophiles, engineers, and professionals who demand uncompromised accuracy.
