Hero (Custom)

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.

Every element of Hero is a combination of reminiscence to our history and it embodies our relentless quest to push the limits of possibility. Its sophisticated design, proprietary technology and extraordinary audio reproduction capabilities make it a class-dominating masterpiece.

Estimated build time: Due to overwhelming demand, our build time is currently 10-12 weeks from the date we receive your ear impressions. For your custom IEMs, it is very important to get ear impressions that are correctly made so that we can create the perfect fit. Read More About It Here. If you send us molds that are not up to our standards, it may necessitate a refit and could subject you to additional fees.

Reviewer's Notes

“I wholeheartedly recommend the Hero to anyone who wants a touch of Zeus XIV coupled with the goodness of Empire’s Weapon 9+ dynamic drivers. Vocal and mid-range lovers take note, this one is a must to audition.”

Read The Review

As someone who is very much into vocals and also enjoys good bass and warm musicality, the Hero satisfied with a smooth, detailed midrange; punchy bass, and highs that were pleasing without being overdone. Hero breathed a lot of life into my test tracks, lending emotion and warmth that really resonated with me.”

Alpha-IV cable

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.

Dual W9+ Subwoofers
Empire Ears Weapon 9 Technology

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 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.

A.R.C. Technology


Empire Ears ARC Effect


ARC (Anti-Resonance Compound) is 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.
