Boasting two of the industry’s most advanced driver technologies, HERO by Empire Ears is truly a standout hybrid IEM with an uncompromising performance ethos focused on delivering the purest connection between listener and IEM.

At the heart of HERO is a proprietary quad-hybrid configuration comprised of triple balanced armatures plus a next-generation W9+ subwoofer. This combination generates legendary bass response while delivering lush, intimate vocals and supreme detail retrieval via a 4-ways synX crossover network backed by ARC resonance mitigation technology.

Dual W9+ Subwoofers - The Empire signature W9+ dynamic driver brought serious performance to the IEM world by combining the breakthrough of an enclosed woofer in a tuned bass-reflex system. Elevating the W9 design formula to its highest level, the W9+ boasts a larger internal coil diameter, more linear excursion envelope along with a more capable suspension to handle peak-to-peak excursion while mitigating distortion. W9+ extinguishes any limits the previous design had and delivers unparalleled bass on all fronts.

BA Drivers - Hero comes equipped with 3 proprietary balanced armature drivers to deliver the signature midrange that the world has come to know and love from Empire Ears. Each driver has been purpose-built to their precise requirements and exacting standards. Only the highest performing components are used.

synX Crossover - Genetically dissimilar from the rest of the IEM world, the Empire synX crossover network truly stands out with countless bespoke methods and technologies protecting it as a unique masterpiece. A marriage of three different driver technologies become symphonized by a unique, proprietary 4-way synX crossover system designed to maximize performance from each and every driver.

ARC (Anti-Resonance Compound) - a proprietary conformal coating that virtually eliminates unwanted vibrations and resonance from within IEMs. ARC effectively increases the mass of the components it’s applied to: every driver, crossover, and sound tube. This gives the internals more solidity while serving as a dampener to absorb the unwanted resonance instead of reflecting them out of phase. With A.R.C. clarity is increased substantially, bass is deeper, and the IEM becomes more efficient.

Bespoke Litz Copper Cable - Hero comes supplied with Alpha-IV (A4), a premium handcrafted 4-core cable comprised of a proprietary 26AWG UPOCC Litz Copper with multi-size stranding. The advantage of multi-sized stranded design within the same encapsulations enables A4 to achieve distinct highs and details due to the signal transmission speed in thinner cable strands, while the thicker size cable strands deliver smoother bass and mids.
