The Spartan IV was passionately engineered to embody discipline, self-denial, and simplicity, in order to achieve a level of technical excellence that would tenaciously hold its own against other in-ear monitors with a higher driver count.
The Spartan IV possesses immense energy, making it an instant fist pumper with its tight bass, engaging mids, and obscenely clear treble. Detail retrieval and coherence is nothing short of superb. It handles everything thrown its way with ample competence via an advanced 4-way crossover network to rule all 4 drivers.
Also, the Spartan IV is available with ADEL™ technology which helps protect your hearing. The ADEL™ option can be added when using the product designer.
Designed and made for the most discerning musician, artist, engineer, and audiophile.

The Spartan IV is the most neutral in-ear monitor in the Olympus lineup. No one element of the frequency response stands out over the other, making it extremely versatile among all musicians. Headroom is vast, allowing you to hear yourself and others in the room without having to focus. Bass is tight and deep, mids are even and engaging, and the treble is extended with ample air. The Spartan IV is most popular among guitarists, vocalists, and sound engineers.
What The Critics Are Saying
“The Spartan is an excellent all-rounder and can handle any genre thrown its way. I need to create some kind of shotgunshane award for this one – maybe the “Rock Star of Fame” award?!” Shotgunshane, CYMBACACVUM.com

4 Balanced Armature Drivers
The Spartan IV boasts 4 proprietary balanced armature drivers, each individually tuned via our advanced crossover network in order to achieve maximum coherence and resolution. Each and every driver at Empire Ears is subject to strict quality control tests before we apply a patent-pending nano magnetic coating. This conformal coating not only resists moisture and other harmful contaminants but also optimizes performance by shielding each driver’s magnetic field to eliminate all interference.
Using only the most exceptional components the Spartan IV’s internals are individually wired and insulated with 7-strand, sapphire and gold, silver-plated copper Litz wires to eliminate acoustic feedback and further soldered with robust, ultra pure quad-eutectic for maximum conduction.
4 Way Passive Crossover System
The Spartan IV features a sophisticated 4-way, 3 crossover points network that’s tuned specifically to magnify performance from every driver. Unlike other in-ear monitor companies, Empire Ears does not use filters or dampers to manipulate the frequency curve. That method of tuning forces the drivers to operate outside of its intended frequency range, often duplicating too many of the same frequencies from numerous drivers. This means you’ll have to turn the volume up to hear what you want.
Our method of tuning allows the drivers to behave naturally as our crossover network is engineered to assign the proper frequencies and levels to the corresponding transducer. The end result is a crystal clear, full range frequency response that can be heard even at low volumes.
Triple Bore Design
The Spartan IV features 3 precision ported sound bores with a designated bore for highs, mids, lows, and the IV technology. Each bore is engineered and hand ported in-house to our exacting clearances in order to achieve optimum phase alignment, consistent performance, and the truest sound possible every time.
Phantom Black Or Titanium Silver Cable
Every Spartan-IV in-ear monitor includes your choice of a 50 Inch Phantom Black, 60 Inch Phantom Black, or 60 Inch Titanium Silver cable.
