Spectrumica The name “Spectrumica” combines “Spectrum,” for the colorful array of sounds it produces, with “Mica,” symbolizing its unique dual transmission system that uses both air and bone conduction. This innovative design features a coil-based CBC bone conduction driver alongside IceLab’s advanced acoustic coordination, providing listeners with immersive and richly layered auditory bliss. Spectrumica offers high-fidelity audio through an advanced 8-driver Quadbrid configuration, blending EST, BA, Dynamic, and Bone Conduction drivers for rich, immersive sound. Features include a custom Mica Cable with Ice Lab’s 3D-HALO shielding for clarity and reduced noise, an Aluminum shell for durability, and ergonomically tuned housing. The P-Sync phase chamber ensures precise synchronization, while premium Japanese Elna capacitors enhance sound accuracy. With dual ear tip options and an aviation-grade build, Spectrumica prioritizes both performance and comfort, designed for an elite audiophile experience. Driver Configuration Spectrumica features an innovative 8-driver structure combining ceramic Dynamic drivers, CBC bone conduction units, Sonion Balanced Armature drivers, and electrostatic drivers. It utilizes Elna audio capacitors, Japan-made MFR metal film resistors, and pure Silver-plated OCC copper internal wiring. Each sound element has been meticulously refined through extensive listening comparisons, achieving optimal acoustic performance. P-Sync Phase Synchronization ChamberBone conduction directly transmits sound to the cochlea through the skull, enhancing low frequencies and spatial depth, though it risks phase misalignment. To address this, IceLab developed the P-Sync phase synchronization chamber, precision CNC-milled to ensure airtightness, reduce resonance, and align air and bone conduction phases. The ceramic diaphragm’s rigidity minimizes deformation under high pressure, enabling sharper responses. Together with the CBC bone conduction driver’s low-frequency capability, this design creates a pure, transparent, and 3D sound. Industry-Leading Sonion DriversBalanced Armature drivers are renowned for their resolution and sensitivity, with Sonion being a leader in the field. Combined with Balanced Armatures, Sonion’s micro-EST electrostatic units, capable of reaching ultra-high frequencies up to 40kHz, deliver seamless, natural sound. Audiophile Grade Sound Spectrumica is expertly designed with carefully selected crossover components, specialized wiring, and tuning ear tips for premium sound. Japanese ELNA capacitors, chosen for their audio quality, and Japanese Metal Film resistors for rhythm precision, enhance performance. To optimize each driver, IceLab uses high-conductivity, gold-plated silver wiring, while thicker OCC copper wiring enriches the dynamic and bone conduction drivers, enhancing low frequencies and delivering a fuller, more immersive sound experience. Housing and Fit The Spectrumica’s design uses aviation-grade Aluminum for strength and optimal bone conduction while remaining lightweight and comfortable. Ice Lab’s ergonomic expertise is evident, as the housing’s 0.4mm thickness at the bone conduction contact point minimizes signal distortion. Two ear tip options—high performance silicone and premium Eletech Baroque—have been rigorously tested to provide rich tonal variations, allowing users to experience the full depth of Spectrumica’s sound capabilities. Custom-tuned Cable The Mica cable for Spectrumica is custom-designed using IceLab’s 3D-HALO Shielding technology, which creates a quieter soundstage and fuller audio. Its OCC single crystal copper core, combined with gold-plated OCC copper in a Litz Type 4S twist, balances dynamic performance and subtlety. With a shielding layer of pure silver and silver-plated wires, the cable enhances high-frequency brightness and ensures clear, transparent sound quality.
