{"type":"firestarter.listing","listing":{"id":"lst_3RXrZFjp","product_name":"TANCHJIM FORCE","category":"In-Ear Monitors","description":"\n\n\nPrecision Engineering from Two Legends\nTANCHJIM and EFFECT AUDIO have come together to co-develop FORCE, combining TANCHJIM’s mastery of acoustic engineering with EFFECT AUDIO’s cable craftsmanship. Every part of the FORCE, from its custom dual dynamic drivers to its signature silver-plated cable, was born from deep collaboration. This partnership ensures a perfect balance of sonic performance and design, offering listeners a refined yet powerful Hi-Fi experience.\n\n\n\n\nPremium Open-Back Design\nUnlike traditional IEMs, the FORCE uses an open-back rear chamber featuring a fine steel mesh that allows air and sound waves to flow naturally. This unique design minimizes internal reflections and ear pressure, creating a more expansive soundstage while significantly reducing listening fatigue. Despite being open-back, the FORCE still offers excellent passive noise isolation and minimal sound leakage thanks to precise engineering and acoustic damping.\n\n\n\n\nFlagship Dual Dynamic Driver Architecture\nFORCE houses two custom dynamic drivers: an 8.2mm beryllium-coated mid-high driver and a 10mm titanium-coated bass driver, both using PU-suspended diaphragms. This setup, based on TANCHJIM’s DMT 4 Ultra driver platform, provides powerful bass, detailed mids, and sparkling treble. The materials and suspension allow for fast transient response, natural tonality, and rich dynamics without distortion—even at high volumes.\n\n\n\n\nHPFD-Seg Frequency Division Technology\nTo ensure each driver performs optimally, FORCE employs TANCHJIM’s proprietary HPFD-Seg crossover technology. This high-precision frequency segmentation keeps both drivers working within their ideal range, reducing harmonic distortion and phase issues often found in multi-driver setups. The result is a cohesive, high-resolution sound that preserves micro-detail and emotional nuance.\n\n\n\n\nCable by EFFECT AUDIO\nThe included cable is handcrafted by EFFECT AUDIO using four strands of silver-plated UP-OCC single-crystal copper in ","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/6_cdaa65c8-a247-4d37-907b-c4ff3129e144.jpg?v=1751535319","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/1_64ab5e62-d783-4f84-86af-cd8a15b2cf2b.jpg?v=1751535319","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/2_149231e4-65f2-48af-94c4-826815005f3f.jpg?v=1751535319","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/3_e0dbf3ba-590d-4294-a16d-bceec57f4fd4.jpg?v=1751535319","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/4_e02dbfa9-0a19-4c98-8218-0a8a36fe7d31.jpg?v=1751535319","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/5_844f8f96-3923-4fe0-916e-7d5b6f7b938d.jpg?v=1751535319"],"price":279.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:44.906Z"},"share_url":"https://firestarter.network/l/lst_3RXrZFjp","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
