Legend X

The flagship of the X Series, the Legend X takes in-ear monitor performance to the highest possible point. Pushing limits at every turn, the Legend X is a world-class, prestige IEM from a new era of uncompromising design and ground-breaking engineering. Every facet of this IEM is extraordinary – from its armament of 7 drivers – including twin Weapon IX 9mm subwoofers, to its industry leading, state-of-the-art 10-way synX Crossover Network. The Legend X is the culmination of everything we strive for. Energetic and addicting, the smooth treble rides across a deep-reaching, impactful low end. Top-tier transparency and separation dance across one of the largest and most three-dimensional sound stages in the market. The Legend X is king.

The Art of Refined Craftsmanship

Unrivaled Build Quality. Every individual component is inspected by hand and held to the highest standard. Then, every in-ear monitor is handcrafted by our passionate craftsmen, from shell construction through to hand lacquering each unit.

From the silver-plated copper wires to the beautifully created jewel tone shells to the rich and exotic imported amboyna burl wood and abalone shell faceplates we use only the finest material to craft every single component of each Empire in-ear monitor, from the inside out.

Every Empire Ears in-ear monitor is proudly designed, engineered, and manufactured in Norcross, Georgia USA.



Nothing beats the isolation and comfort of a custom shelled in-ear monitor. Provide us with molds of your ears and we will hand-craft an in-ear monitor that delivers the highest possible quality of comfort, isolation and sound.

Hybrid Design

Empire Ears feature a combination of both proprietary balanced armature speakers and dynamic range subwoofers in order to deliver maximum clarity while achieving a powerful low end response. By combining the two we can create a listening experience unique in its fullness and unrivaled in its sound.

Balanced armature drivers are the professional’s standard. True, honest, non-fatiguing sound across the entire frequency range with tighter responses and super broad dispersion. Dynamic drivers use a diaphragm push sound into the ear resulting in rich tones and emphatic, visceral bass.

Anti-Resonance Compound (A.R.C.) Technology

A.R.C. is a proprietary combination of advanced polymers coating that adds to the relative mass of each component dampening the resonant vibrations. Is designed to  eliminate unwanted vibrations and resonance from within the in-ear monitors themselves. With A.R.C. clarity is increased substantially, bass is deeper, and the IEM becomes more efficient overall.

The specific qualities of the A.R.C. were inspired by natural resins. In fact, natural rosin has seen use in musical instruments for centuries, being applied to the strings of a violin for its stick-slip friction component that allows a note to be played more reliably while not affecting the pitch or duration of the note due to it’s anti-resonance qualities.

By utilizing our A.R.C. we can cut down dramatically in-shell resonance. The result is a much cleaner sound with no phase interference, a better listening experience without fatigue and an isolation that you can genuinely appreciate for hours on end.

synX Crossover Networks

Developed with over 30 years audio manufacturing experience the synX Crossover is the industry’s most advanced IEM crossover technology. 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 is a supercharged crossover design that designates more individual audio bands per driver than any other crossover technology currently in existence. By creating an ultra-wide, multi-channel highway our engineers can manipulate specific parts of the frequency range in order to precisely craft the target response and eliminate any signs of phase incoherence between the drivers. Alternatively, mixing engineers, performers and audiophiles will have full control of the drivers when equalizing through a mixing console or digital audio player.

We install, by hand, a variety of top secret resistors, electrolytic capacitors, splitters, filters and other technologies, soldered in-line to tune our in-ear monitors.

synX Crossover Network features a myriad of other advantages including:

-Ultra-Wide Frequency Bandwidth: The Bravado, our entry level model, produces a super-wide 8hz to 40khz frequency range, offering listeners unparalleled sound quality and details.

-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.


After nearly 2 years of relentless R&D Empire is proud to announce the Weapon IX (W9), a proprietary 9mm rare-earth magnet subwoofer with the ability to deliver extreme output, accurate dynamics and sublime sound quality all at the same time.

This proprietary dynamic driver brings the full force of your music to your ears, hitting you with the essence of a true subwoofer. This visceral sensation brings a depth to the experience that is unmatched in the in-ear monitor world. Every kick drum hit, snare triplet, or reverberation of a slapped bass note will be felt as much as it is heard.

In the case of Legend X IEMs we use two Weapon IX subwoofers, one of which is dedicated strictly to subsonic frequencies for the low end and the mid lows. This means that one subwoofer produces a rich and luscious tone while the other provides the air pressure of the hit. By not artificially upping the bass we maintain our enormous, 3D soundstage.


Bespoke, handcrafted Ares II cable by Effect Audio. The Ares II boasts a proprietary blend of 26 AWG UPOCC Litz copper with ultra-flexible insulation for maximum signal speed transmission, performance, and ergonomics. Each cable is terminated in an ultra durable 3.5mm, 24k Oyaide gold plated right angle plug. Alternatively, for our audiophile clientele, we also offer 2.5 and 4.4 balanced terminations at no additional charge.
