Empire Ears ESR Universal

The ESR is the next model in Empire Ear’s EP Series multi-balanced armature IEM line-up after the EVR. As a studio reference model, the ESR demonstrates all of U.S. Based Empire Ear’s unique attention to detail. Every Empire Ears IEM incorporates their SynX Crossover technology, which employs complex multi-way crossovers to divide frequencies between drivers, allowing for precise tuning and minimal phase distortion. Empire Ears also coats the internal parts of their earphones with a unique Anti-Resonance Compound that increases mass damping on the driver units and decreases resonances. These technologies allow for a cleaner, more precise sound.

ESR stands for Empire Studio Reference, and this model was designed as a reference monitor for an accurate sound. Slightly warmer than the vocal-oriented EVR, the ESR uses 3 balanced armature drivers to deliver a natural balanced sound with some added high frequency detail. This is a good, punchy all rounder, but if you prefer more bass in your music try Empire's hybrid models like the Bravado or Vantage.

Empire Ears Universal IEMs come with high quality, 2-pin double braided cables from the famed Singapore-based Effect Audio, as well as high quality silicone ear-tips from the Japanese company Final Audio. Despite the amount of technology packed into each unit, Empire Ears IEMS are lightweight and comfortable. The ESR is also available from Mindisc as a custom model matched to your ears and design preferences.
