Feel the magic with the Empire ESR MKII

Equipped with two state-of-the-art driver technologies and modules to control them effectively, the Empire Ears ESR MK2 reproduces your music accurately and consistently.

Three Balanced Armature drivers handle the low, mid, and high frequencies, while two Electrostatic drivers handle the high and ultra-high frequencies. The result is a studio-reference sound with excellent detail and clarity.

Experience smooth, crisp sound through the ESR MK2 with SynX technology

Multi-driver IEMs need a competent crossover tech to ensure their drivers produce their intended sound accurately. With Empire Ears' SynX Tech, you can experience the cleanest sound with unmatched cohesion for a smooth and immersive listening experience.

Enjoy electrostatic drivers to their best with ESR MK2's EIVEC technology

Electrostatic drivers require plenty of power to deliver their full potential. When paired with Balanced Armature drivers in a hybrid setup, the EST drivers' overwhelming power can drown out the Balanced Armatures, resulting in a muddy and incohesive sound.

Empire Ears' EIVEC module prevents this by ensuring the EST drivers deliver a full, clean, and rich high-end while allowing the BA drivers to shine for a balanced sound.

Eliminate rattles with the ESR MKII's A.R.C technology

The Empire Ears MKII's components are intentionally made heavier to eliminate rattles that could potentially cause unwanted resonances over time.

Through Anti-Resonance Compound (ARC) technology, you can enjoy a clean and distortion-free bass response for those addictingly punchy beats.

Enjoy enhanced transmission speed with the Empire Ears ESR MKII IEM and included handcrafted cable

Having the best driver setup and crossover technology won't amount to anything if your cable cannot deliver the necessary information from your source to your IEMs. With the ESR MKII Alpha IV cable, you'll never worry about muddy or distorted sound.

The Alpha IV Cable features varying strand sizes to maximize frequency range and sound. Low frequencies travel through the thicker wires for a smoother and richer bass and midrange response, while treble travels through the thinner strands for a clean and detailed sound.
