The ESR boasts an amazingly tight, accurate sound with enormous dynamic range and unprecedented frequency response
Empire Ears - ESR
“Building forth on the all-round capabilities of Empire Ears' appraised Spartan, the ESR offers similar neutrality, with an improved tuning throughout the spectrum. Combining greater body to the sound with a pleasant touch of warmth results in a more engaging midrange, while further improved extension provides even greater resolution.
Accordingly, the ESR has evolved as the pinnacle of balance, providing one of the most linear signatures in Empire Ears' lineup. A bass that is neutral in quantity, but high in definition, and quick in pace; a smooth midrange that holds the line between forward and laid-back, and a precisely-tuned treble, delicately balancing between clear and smooth. But more than anything the ESR is a detail monster, offering the pinpoint precise imaging, clean separation, and high resolution of top-tier competitors, at a mid-tier price.”

Grammy Award Winning Sound
Every aspect of the ESR was conceived, designed, and crafted to faithfully reproduce what the artist had intended. With the expertise of producers and mix engineers, including 2x GRAMMY Award winner, Michael Graves, we were able to understand firsthand what they require from in-ear monitors.
synX Crossover Technology
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 precision craft the target response and eliminate any signs of phase incoherence between the drivers. Alternatively, mix engineers and audiophiles will have full control of the drivers when equalizing through a mixing console or digital audio player. synX is the industry’s most advanced IEM crossover technology with each model featuring its own uniquely designed synX network.
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 ESR 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 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.
The ESR 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.
Bespoke Handcrafted Cables
Every ESR iin-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.
Effect Audio’s extensive engineering and manufacturing background gives them the edge over all other cables. After extensive testing with numerous other cable manufacturers we’re proud to announce our official partnership with Effect Audio to bring you some of the finest cables in the industry and to ultimately defeat the weak link in IEMs.
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.
