Empire Ears Legend X (Universal)

United States flag

Built for bass devotees, the Legend X Universal unleashes visceral sub-bass with enormous scale while preserving a super-wide soundstage and incisive vocal placement. The Headphone Show found its grand, V-shaped presentation unusually distinctive, pairing club-ready slam with strong resolution, luxurious acrylic craftsmanship, and a clear center image that keeps the excitement precisely focused.

Pros

Exceptional bass impact, bloom, and large-scale presentation for bass-focused listening.

Super-wide staging with strong lateral definition and a distinct, forward center image.

Exceptionally clean acrylic construction, with seamless faceplate integration and a clear view of internal components.

Cons

V-shaped tuning recesses male vocals while the upper mids can make female vocals sound sharp.

Bass texture and control trail its sheer impact; notes can sound smoothed over and mid-bass can become less disciplined.

Large shells may protrude in smaller ears, and the connectors do not fully seat into the earpieces.

What Reviewers Are Saying

"There is really nothing else on the market like it."

— The Headphone Show

SOUND QUALITY PERFORMANCE 84/100

The Legend X delivers an unapologetically large, bass-led V-shaped presentation with unusually expansive lateral staging and sharply defined central images. Its technical strengths are tempered by a recessed lower midrange, bass that can lose control and texture, compressed treble character, and restrained small-scale dynamic contrast.

Bass

89/100

Bass is the defining attraction: the reviewer calls it an "absolute bass cannon," with huge note size, bloom, and slam that will strongly appeal to bass-focused listeners. Texture and control are less convincing, however, as attacks can sound stretched and smoothed over, while abundant mid-bass can become less disciplined than flagship peers.

Midrange

78/100

The V-shaped balance leaves the midrange comparatively recessed, particularly for male vocals. An assertive upper-midrange rise brings female vocals forward, but can make them sound sharper than the rest of the vocal range.

Treble

80/100

Treble is clearly present rather than rolled off, with emphasis on the leading edge of percussion. The reviewer finds its quality less remarkable than the bass or staging, citing a somewhat compressed character and limited distinction between individual hits.

Resolution Separation

86/100

The review considers the Legend X technically capable and resolving despite its strongly elevated bass response. Its large low end can still add density to the presentation, so fine detail is not always presented with the clearest or most open sense of separation.

Soundstage Imaging

93/100

Imaging is a major strength, with a super-wide stage, strong lateral definition, and a notably distinct, forward center image for vocals. Stage height is above average, though the reviewer does not consider it among the very best in its class.

Dynamics Coherence

77/100

It produces plentiful bass slam and a grand, larger-than-life scale, but this does not translate into equally convincing dynamic gradation. Quieter passages remain too elevated and larger dynamic swings can sound flatter than intended.

FIT COMFORT ISOLATION PERFORMANCE 75/100

The universal shell is reported to fit well, but its larger body can protrude noticeably from smaller ears. Long-term comfort is therefore likely to depend more than usual on ear size, while the available review provides little direct discussion of passive isolation.

Seal Stability

84/100

The reviewer reports a good fit and does not identify seal loss or fit-related bass variation. The larger shells may be less discreet in smaller ears, but there is no indication that they routinely fail to maintain a seal.

Comfort

82/100

Fit is described as good overall, and the supplied Final E tips are said to be very comfortable. The shells are definitely on the large side and protrude in the reviewer's smaller ears, which may limit comfort for some listeners.

Isolation

50/100

The review says little about real-world passive isolation. No specific comparison with other sealed IEMs or report of outside-noise attenuation is provided.

Assessments of Build Quality, Usability, and Overall Propositions.

Build Accessories

89/100

Construction receives especially strong praise: the acrylic shells are exceptionally cleanly finished, with seamless faceplate integration and a clear view of the internal components. The protective Pandora case, comfortable Final E tips, and Effect Audio cable are useful inclusions, although the case is bulky and the reviewer would prefer recessed or more fully seated connectors.

Value for Money

73/100

At roughly $2,279 to $2,400, the reviewer cannot offer a straightforward recommendation against competing flagship IEMs. Its singularly extreme bass-and-stage presentation serves a distinctive niche, but the price is difficult to justify for listeners seeking a more balanced all-round flagship.

Manufacturer's Description — Empire Ears

At long last the Legend has returned to the throne to push the limits of in-ear monitor performance to its highest point ever. Experience a world-class prestige IEM and a new era of uncompromising design and performance. From its arsenal of 7 proprietary drivers (including twin sequential W9 subwoofers) to its industry leading, state-of-the-art 10-way synX crossover network, the Legend X is the culmination of everything extraordinary we do at Empire.

Hybrid Technology

The Empire X series model features a combination of both proprietary balanced armature speakers and dynamic range W9 subwoofers in order to deliver maximum clarity while achieving a powerful low end response. Each model is further tuned with a specially designed synX crossover network to achieve studio monitor levels of audio reproduction effortlessly and faithfully.


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. The keys to these performance capabilities lie at the very core of its design, where the woofer is enclosed in a tuned bass-reflex system with a front-firing sound port and rear-firing vent for maximum efficiency.


Conventional dynamic drivers and passive radiators (a speaker without the magnet and coil) often suffer in low octave frequencies and are heavily dependent on internal shell enclosures for volume, limiting form factor and vastly reducing efficiency with limited extension. The W9 is superior in its custom port tuned design, reaching frequencies even lower than its target response while mitigating distortion as the woofer isn’t required to move as far near resonance frequency.


Every W9 subwoofer is hand assembled to our exacting quality standards in our Norcross, Georgia laboratory


Proprietary Drivers


The Legend X utilizes a number proprietary balanced armature drivers by Knowles and Sonion, each one purpose built for a specific target response. Our drivers feature specialized reeds and low-mass diaphragms to reproduce incredible detailed, true-to-recording sound while remaining efficient enough to be powered by everyday devices.


Furthermore each Empire driver utilizes a NASA-born ferromagnetic liquid technology, Ferrofluid, to dampen acoustics peaks and reduce vibrations in combination with our A.R.C. technology. The end result is extraordinary clarity and increased shock durability.


A.R.C. Technology

Balanced Armature (BA) drivers are vastly used in the IEM industry due to their small footprint and ultra efficient designs however they suffer from resonant behaviors that may cause peaks, unwanted vibrations, and distortion. To help mitigate this our drivers utilize Ferrofluid between the magnets and armature to provide a wide range of damping values, eliminating the need for a damping screen in the port tube.


Despite this a secondary peak can still occur from the other components interacting with the drivers. Driver peaks can cause fatigue, distortion, and ultimately affect the way music sounds. We sought out to create a remedy for this and after years of relentless R&D we’re proud to announce A.R.C. (Anti-Resonance Compound), a proprietary coating that virtually eliminates unwanted vibrations and resonance from within IEMs.


A.R.C. 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 overall.
