Cup style More information
Open-back headphone designs are often higher-performance but have poor noise isolation and leak sound. Closed-back designs provide better noise isolation and leak less sound.


Wearing style More information
Over-ear headphones sit over your ear and surround your ear with a ring of padding. On-ear headphones are padded but rest on top of your ear. In-ear monitors are worn inside your ear canal.


Driver type More information
Speakers and headphones use a device called a 'driver' to create sound. Different types of drivers have different strengths and weaknesses, but can all produce great sound. Common varieties include dynamic, planar magnetic, and electrostatic.

Dynamic, Balanced Armature

Connectivity More information
Connectivity refers to the method in which the headphones connect to the audio source. Headphones can be either wired or wireless.

The Legend X In-Ear Monitor Headphones are the latest flagship from Atlanta Georgia's Empire Ears.

The Empire Ears Legend X features 10-way crossover, 7 proprietary drivers (include 2 W9 Subwoofers, 2 Mid, 1 Mid-High, 1 High and 1 Super High) and Empire Ears' A.R.C. Resonance Mitigation Technology to produce a satisfying V-shaped sound.

If you're looking for extra low-end, the Legend X is perfect.

synX 10-Way Crossover

Empire Ears has implemented their latest synX crossover technology in the Legend X. The synX crossover designates more individual audio bands per driver than any crossover technology in existence. The engineers at Empire Ears can manipulate specific parts of the frequency range to precision craft the target response and eliminate signs of phase incoherence between drivers. synX powered in-ear monitors have incredible stereo separation and smooth phase response, leading to hyper-realistic imaging and staging.

synX has plenty of advantages over competing crossover technologies and here are a few of them:

Ultra-Wide Frequency Bandwidth

The Legend X produces a super-wide frequency range, offering listeners unparallel 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, they have created a unique combination of handpicked resistors, electrolytic capacitors, and filters. This ensures the cleanest signal path while offering an exceptionally low noise floor.

Low Distortion

Extremely low distortion means 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 then soldered with highly conductive, ultra-pure silver and gold Mundorf Supreme for maximum signal transfer.

Seven Proprietary Drivers

The Empire Ears Legend X contains seven proprietary drivers; 2 W9 Subwoofers, 2 Mid, 1 Mid-High, 1 High and 1 Super High. The W9 subwoofers allow the Legend X to hit hard in the low-end while the balanced armature drivers deliver outstanding clarity and detail throughout the frequency range. Each model is further tuned with a specially designed synX crossover network to achieve studio monitor levels of audio reproduction effortlessly.

W9 Subwoofers

The W9 Subwoofers (Short for Weapon IX) are a result of two years of research and development from Empire Ears. The W9 consist of 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 woofer is enclosed in a tuned bass-reflex system with a front-firing sound port and rear-firing vent for maximum efficiency and unmatched performance. 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 in Empire Ears laboratory in Norcross, Georgia.

Proprietary Balanced Armature Drivers

The Legend X utilizes a number of proprietary balanced armature drivers by Knowles and Sonion, each one purpose-built for a specific target response. Empire Ears' 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.

Bespoke Handcrafted Cables

Every Legend X in-ear monitor includes a 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. However, the option for either 2.5mm or 4.4mm terminations are also available at no additional charge.
