Juzear, in collaboration with Zeos from Z Reviews, has crafted the Defiant as a statement in hybrid IEM engineering. Each side houses a 1DD+3BA driver array — a third-generation 10mm dynamic driver paired with a newly designed composite mid-frequency BA and a customized high-frequency BA. A three-way crossover with a fully damped acoustic structure and gold-plated PCB ensures pristine frequency division. A specially developed micro-perforation pressure balance system ensures a secure, comfortable fit for extended listening. Bundled with the premium FLARE IEM upgrade cable featuring a hybrid 6N SPOCC+SCCW structure and interchangeable termination plugs, the Defiant is a complete, uncompromising listening experience.

Four-Driver Hybrid Architecture

Each side of the Defiant houses a four-driver hybrid configuration: a third-generation 10mm dynamic driver with PU composite diaphragm and a powerful Neodymium magnet for deep, authoritative bass, complemented by three precision-tuned Balanced Armature drivers for unmatched midrange clarity and extended high-frequency response.

Three-Way Crossover with Fully Damped Acoustic Tubes

The Defiant's three-channel, fully damped acoustic crossover eliminates multi-driver distortion and optimizes sound transmission. Each acoustic tube is individually custom-damped for superior tuning precision. The 3rd-generation dynamic driver handles the low end with authority, a dual composite BA delivers rich midrange, and a custom-developed BA extends the highs with effortless clarity.

DLP 3D-Printed Shell with Precision CNC-Milled Faceplate

The Defiant's ear shells are produced using high-precision DLP 3D printing technology, crafted from premium skin-friendly resin for an ergonomic, all-day comfortable fit. The CNC-milled faceplates with nickel metal accents lend the Defiant a refined, artisanal aesthetic. Available in two distinguished colorways: Defiant Rainbow and Jade Green.

Premium High-Purity Hybrid Stock Cable

The Defiant ships with a FLARE IEM upgrade cable featuring a hybrid 6N SPOCC+SCCW wire core with 70 strands per conductor (280 strands total). The cable uses 0.78mm two-pin connectors and an interchangeable termination plug system, with both 3.5mm and 4.4mm plugs included.
