“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
How do crossovers work?
Think of a crossover network as an audio traffic officer, directing highs to your tweeters, midrange to your speakers, and bass to your subwoofers. This is essentially what a crossover does; it takes an input signal and splits it into separate audio bands. Could you imagine having numerous speakers with just a few dedicated audio bands? It would cause a massive audio pile up, forcing the wrong speakers to reproduce the wrong frequencies constantly. We avoid all of this by utilizing specially designed drivers for designated frequency ranges and further maximizing their potential with our latest crossover technology, synX.
The ESR utilizes a number of 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 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.
Effect Audio’s extensive engineering and manufacturing background gives them the edge over all other cables. After extensive testing with numerous other cable manufacturers, Empire Ears is 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.
Proudly Handcrafted In The USA
Empire Ears has long prided itself for home-grown craftsmanship, with artisans donning lab coats and honing years of OEM factory experience before being entrusted to handle the Empire lineage. While several of our competitors have taken their manufacturing overseas or have turned to automation we’ve remained true to our handcrafted, made-in-USA roots to not only provide jobs to our local community but to ensure that quality is never compromised.
Every Empire Ears in-ear monitor is proudly designed, engineered, and manufactured in Norcross, Georgia USA.
