Every decision made in the recording, mixing and mastering process relies on the truth and that’s explicitly what the Empire Studio Reference (ESR) MKII delivers; Pure, neutral and unadulterated sound reproduction with unrivaled detail retrieval. The ESR MKII is the next generation of the ESR and is consequently the best studio reference in-ear monitor we’ve ever crafted.

The ESR MKII features an upgraded 5 driver hybrid configuration, consisting of triple balanced armatures and dual electrostatics, alongside a completely reengineered 4-way synX crossover network driven by EIVEC and ARC technology to effortlessly reproduce the sonic transparency and critical details needed for monitoring, mixing and mastering.

The ESR MKII is Empire’s flattest in-ear monitor and it delivers true-to-recording dynamics, ultra-fast transient response and wide dispersion to meet the needs of music, cinema and broadcast production.

Alpha-IV

At Empire Ears we believe that an extraordinary IEM requires an extraordinary cable. We're proud to introduce Alpha-IV (A4); a premium handcrafted 4 core cable comprised of a proprietary 26AWG UPOCC Litz Copper with multi-size stranding. The advantage of multi-sized stranded design within the same encapsulations enables A4 to achieve distinct highs and details due to the signal transmission speed in thinner cable strands, while the thicker size cable strands deliver smoother bass and mids.

Brushed Silver - Keeping It Classy

The ESR MKII features a premium Brushed Silver aluminum faceplate for a sleek, professional design suitable for any environment.

A Studio Reference Hybrid

Equipped with two of the industry’s most advanced driver technologies, the ESR MKII is truly a standout IEM with an uncompromising performance ethos focused on delivering only the most exceptional accurate monitoring experience.

BA Drivers

ESR MKII comes equipped with 3 proprietary balanced armature drivers divided across 3 separate frequency bands for maximum coherence and resolution.

EST Drivers

ESR MKII masterfully manipulates dual electrostatic drivers in unison with our proprietary EIVEC technology to reproduce a remarkable 10Hz-100kHz frequency range. The ultralight moving membrane within ESR MKII’s electrostatic drivers give the most accurate transient response, resulting in unparalleled clarity, separation and detail.
