Empire Ears HERO
Designer's Notes
“Hero is relentless, fierce and unapologetic – a renunciation of rules, preconceptions and everything that’s expected from it. It represents a tour de force of Empire’s expertise and craftsmanship, elevating musicality presentation to a level non-existent in its tier. With DNA sourced directly from Legend X and Zeus XIV, Hero reveres our past to emulate flagship levels of performance without the flagship admission.
The heart of Hero is a proprietary quad hybrid configuration comprised of proprietary triple balanced armatures and a next generation W9+ subwoofer. This staunch 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. Hero’s sophisticated design, proprietary technology and extraordinary audio reproduction capabilities make it a class-dominating masterpiece.”

Handcrafted Alpha-IV 26AWG UPOCC Copper Litz Cable
Proprietary Technologies
Alpha-IV

At Empire Ears we believe that an extraordinary IEM requires an extraordinary cable. We’re proud to introduce 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.
A4 features a durable, overmolded .78 2-pin connector offered with either a 3.5mm right angle or 2.5mm balanced termination and improves upon the previous cable design. 2.5mm to 4.4mm adapters are available HERE.


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

Weapon IX+
Our 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.
Every W9+ subwoofer is hand assembled to our exacting quality standards in our Norcross, Georgia laboratory.
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 of these drivers has been purpose built to our precise requirements and exacting standards. We work closely with our vendors to ensure that only the highest performing components are used.

synX Crossover Technology
Legendary Crossover Network
Genetically dissimilar from the rest of the IEM world, our synX crossover network truly stands out with countless bespoke methods and technologies protecting it as a unique masterpiece. A marriage of 3 different driver technologies become symphonized by a unique, proprietary 8-way synX crossover network designed to maximize performance from each and every driver.

synX advantages
synX powered in-ear monitors have remarkably high stereo separation and smooth phase response, leading to more dynamic realistic imaging and staging for both live and studio use. synX features a myriad of other advantages including:
Ultra-Wide Frequency Bandwidth: The Legend X produces a super-wide frequency range, offering listeners unparalleled sound quality and details that bests even the most high-end headphones on the market.
Best Signal-to-Noise: In order to ensure that all of the industry-leading sound quality is heard in your ears we’ve worked to create a unique combination of handpicked resistors, electrolytic capacitors, and filters in order to ensure the cleanest signal path possible while offering an exceptionally low noise floor.
Low Distortion: Extremely low distortion means that every nuance in your mix will be reproduced faithfully without audible artifacts.
Maximum Signal Transfer: Every driver and crossover is individually wired and insulated with 7-strand, UPOCC Litz wires to eliminate acoustic feedback and further soldered with highly conductive, ultra pure silver and gold Mundorf Supreme for maximum signal transfer.
