{"type":"firestarter.listing","listing":{"id":"lst_9Yb4j8C2","product_name":"Kiwi Ears Halcyon","category":"Early Bird Products","description":"\nHear Every Detail, Feel Every Note\nThe Kiwi Ears Halcyon is the world's first MEMS + 1DD + 3BA tribrid IEM, combining cutting-edge MEMS technology with a dynamic driver and custom balanced armatures for full-spectrum sound. CNC-milled aluminum housings and precision acoustic engineering deliver wide soundstage, clear mids, deep bass, and sparkling trebles. \n\n\n\n\nMEMS Technology Meets Tribrid Setup\nThe Halcyon is one of the first in-ear monitors to implement a tribrid configuration utilizing cutting-edge solid-state MEMS (Micro-Electro-Mechanical Systems) technology. MEMS is a solid-state speaker using silicon chips and passive components to generate a piezoelectric effect. Without traditional acoustic components such as coils and diaphragms, MEMS excels in speed and high-resolution performance, particularly in the ultra-treble frequencies. Combined with traditional balanced armature and dynamic drivers, Halcyon achieves one of the world’s first tribrid configurations to benefit from MEMS’ ultra resolution.\n\n\n\n\n\nBest-In-Class Tonal Signature\nThe Halcyon combines technical performance with exceptional tonal balance. Following Kiwi Ear’s famed tonal signature, the Halcyon provides a studio monitor-like neutral tuning with an enhanced sub-bass boost. The sub-bass shelf features a balanced 8dB sub-bass boost, which is cleanly cut at 200Hz for bloat-free midrange. The mids are natural and clean, mirroring the accuracy of studio monitors. This enhances instruments and vocals and provides exceptional imaging and layering precision. The treble peaks precisely at 3kHz for a perfect pinna gain compensation, and has a treble decay that is fitted to modern tuning preference signatures.\n\n\n\n\n\nExcellence in Driver Technology\nThe Halcyon combines the best of both traditional and modern driver technologies. A 10mm composite diaphragm dynamic driver powers the sub-bass for a powerful, yet well-controlled and tight bass response. This provides a real subwoofer-like bass experience, whi","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KiwiEarsHalcyon_6.jpg?v=1778495116","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KiwiEarsHalcyon_2.jpg?v=1778495115","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KiwiEarsHalcyon_1_1.png?v=1778495115","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/Kiwi_Ears_Halcyon_5.jpg?v=1778495233","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KiwiEarsHalcyon_23.jpg?v=1778495115","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KiwiEarsHalcyon_24.jpg?v=1778495116","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/Kiwi_Ears_Halcyon_17.jpg?v=1778565505","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/Kiwi_Ears_Halcyon_18.jpg?v=1778565505","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/Kiwi_Ears_Halcyon_19.jpg?v=1778565505","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/Kiwi_Ears_Halcyon_20.jpg?v=1778565505","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KiwiEarsHalcyon_4.jpg?v=1778495116","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/KiwiEarsHalcyon_3_1.png?v=1778495116","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/Kiwi_Ears_Halcyon_8.jpg?v=1778495233","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/111111111111.jpg?v=1778841887"],"price":259,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:43.993Z"},"share_url":"https://firestarter.network/l/lst_9Yb4j8C2","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
