Advanced tri-brid engineering. High-end sound made more accessible.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNamed after the vivid colors of autumn foliage, the \u003cstrong\u003eJomo Audio Koyo\u003c\/strong\u003e is a premium tri-brid in-ear monitor designed to bring together natural materials, sophisticated acoustic engineering, and exceptional value.\u003c\/p\u003e\n\u003cp\u003eKoyo combines a \u003cstrong\u003e10mm dynamic driver, three balanced armature drivers, and a 6mm planar magnetic super tweeter\u003c\/strong\u003e within Jomo Audio’s graphene-infused \u003cstrong\u003eAC2X Asymmetrical Co-Axial Acoustic Chamber\u003c\/strong\u003e. The result is a full-range presentation designed for powerful, textured bass, articulate mids, precise imaging, and airy, extended treble.\u003c\/p\u003e\n\u003cp\u003eBeyond its acoustic performance, Koyo is built to be as distinctive as it sounds. Stabilized maple hardwood, stainless steel, and a gold-plated brass open-back faceplate give every pair a character of its own—one that continues to evolve with age and use.\u003c\/p\u003e\n\u003ch2\u003eNatural Stabilized Maple Shell\u003c\/h2\u003e\n\u003cp\u003eKoyo’s housing pairs \u003cstrong\u003estabilized maple hardwood with a precision-finished stainless steel frame\u003c\/strong\u003e, creating a distinctive balance between organic craftsmanship and modern engineering.\u003c\/p\u003e\n\u003cp\u003eRather than covering the wood beneath a glossy lacquer, Jomo Audio uses a carefully polished and waxed finish that preserves its natural grain and tactile character. This approach also retains more of the wood’s natural acoustic properties, contributing to Koyo’s warm, organic presentation and spacious sense of ambience.\u003c\/p\u003e\n\u003cp\u003eBecause genuine wood naturally changes over time, each Koyo can gradually develop its own patina, deepening in character with use. Natural variations in grain and appearance also mean no two pairs are exactly alike.\u003c\/p\u003e\n\u003ch2\u003eFlowMax Open-Back Design\u003c\/h2\u003e\n\u003cp\u003eA striking \u003cstrong\u003eCNC-machined, gold-plated brass FlowMax grille\u003c\/strong\u003e forms the centerpiece of Koyo’s open-back architecture.\u003c\/p\u003e\n\u003cp\u003eEngineered to optimize airflow and acoustic dispersion, the FlowMax design helps Koyo create an open, natural-feeling soundstage while reducing the closed-in presentation that can occur with conventional sealed IEM housings.\u003c\/p\u003e\n\u003cp\u003eThe intricate brass structure also provides a distinctive visual contrast against the natural maple shell and stainless steel frame, giving Koyo an unmistakably boutique appearance.\u003c\/p\u003e\n\u003ch2\u003eSophisticated Tri-Brid Driver System\u003c\/h2\u003e\n\u003cp\u003eKoyo combines three complementary driver technologies, allowing each to focus on the frequencies it reproduces best.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e1 × 10mm Custom Silk-Diaphragm Dynamic Driver\u003c\/strong\u003e\u003cbr\u003eProduces deep, textured bass with satisfying physical impact and natural decay.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3 × Precision Balanced Armature Drivers\u003c\/strong\u003e\u003cbr\u003eDeliver articulate mids, high levels of detail, and precise imaging.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e1 × 6mm Nano Planar Magnetic Super Tweeter\u003c\/strong\u003e\u003cbr\u003eExtends the upper frequencies with smoothness, sparkle, and an airy sense of space.\u003c\/p\u003e\n\u003cp\u003eA \u003cstrong\u003e4-channel C.S.U. crossover circuit\u003c\/strong\u003e integrates the five-driver system for a coherent presentation across the frequency spectrum.\u003c\/p\u003e\n\u003ch2\u003eAC2X Graphene-Infused Acoustic Chamber\u003c\/h2\u003e\n\u003cp\u003eAt the heart of Koyo is Jomo Audio’s \u003cstrong\u003eAC2X Asymmetrical Co-Axial Acoustic Chamber\u003c\/strong\u003e, manufactured from graphene-infused 3D-printed resin.\u003c\/p\u003e\n\u003cp\u003eThe AC2X architecture places the bass and ultra-high-frequency drivers within a carefully engineered shared cavity while using an asymmetrical design to control interactions between the frequency extremes. This helps preserve low-frequency definition while maintaining clean, extended treble.\u003c\/p\u003e\n\u003cp\u003eThe chamber is also designed to create a stable operating environment for Koyo’s balanced armature drivers. Its graphene-infused resin increases structural rigidity and provides additional damping, helping suppress unwanted micro-vibrations and internal resonances.\u003c\/p\u003e\n\u003cp\u003eThe result is greater control, lower unwanted resonance, tighter bass, improved clarity, and a more natural tonal balance—allowing Koyo’s tri-brid driver array to perform as a cohesive system rather than a collection of individual drivers.\u003c\/p\u003e\n\u003ch2\u003eOil-Infused OCC Copper \u0026amp; Silver Cable\u003c\/h2\u003e\n\u003cp\u003eKoyo includes a premium \u003cstrong\u003eoil-infused coaxial cable constructed from OCC single-crystal copper and OCC single-crystal silver conductors\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe copper-and-silver blend is designed for highly transparent signal transmission, pairing the natural tonal qualities associated with copper with the excellent conductivity of silver.
