Empire Ears ESR MKII Universal Fit IEM

The Empire Ears ESR mkII is a universal fit, reference in ear monitor. The ESR mkIIs from Empire Ears are designed to provide mixing and mastering engineers true-to-recording dynamics, ultra fast transients, super-wide dispersion and the flattest response possible.

The ESR MK II is powered by three triple-balanced armatures combined with dual electrostatics, culminating in a five-driver hybrid configuration.

Each part of the driver array is supported by Empire Ears' specially developed synX crossover network, EIVEC electrostatic control technology, plus ARC anti resonance treatment to avoid contamination of the soundstage.
