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.
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.
