Aurum
Craft Ears Aurum is the crowning achievement of our work so far and the highlight of the Genesis series. As the flagship model, there could be no better name than "Aurum," which means "Gold." Especially because the qualities of this element, such as its natural shine, were our inspiration for the exclusive design and sound signature of Aurum.

Sound from the soul
Aurum is our first tribrid model, equipped with a specially arranged dynamic driver, four carefully selected armature drivers, and two electrostatic Sonion drivers.
Our proprietary technologies make it possible to set new standards for IEMs with three different drivers. As a result, Aurum offers an exceptional extension at both ends, excellent coherence, a large sound stage, precise imaging, and remarkable detail reproduction, while the sound remains natural, gentle, and balanced.

Discover the genesis of flawless sound
Craft Ears always aims to push boundaries further to achieve the best possible sound. Our goal is to create something new and fresh. Aurum is our first tribrid IEM because we believe that three different types of drivers allow us to produce an extraordinary and highly technical sound that still has great tone and tonal balance.
Craft Ears Aurum is a balanced IEM with great tonality and breathtaking extension at both ends. Its foundation is very deep and profound, with precise subbass and controlled, structured, and impressive midbass. Every lower note is rendered with much attack and power but never overshadows other frequencies. The midrange is neutral and very detailed, yet has good body and is soft. Thanks to these qualities, voices can shine and easily convey an artist’s emotions.
The treble is a part of the Aurum sound that we are especially proud of. It is very detailed yet gentle, with good cymbal reproduction. The extension could be compared to much more expensive IEMs. It leads to a very airy presentation and a large sound stage. Aurum offers a sense of depth, precise imaging, and a holographic impression with strong channel separation. Our flagship is a perfect blend of technique, naturalness, and musicality.
Unprecedented technologies
The exceptional sound of Craft Ears Aurum is not only possible thanks to carefully selected drivers but also due to our own technologies.
We chose a 10 mm PEN dynamic driver that works like a true subwoofer. It delivers a clear, fast, and full but not overwhelming subbass. The light yet stiff PEN membrane combined with the N35 magnet ensures unparalleled bass—precise dynamics and exquisite sound quality at the same time.
Four symmetrical drivers with a carefully selected five-way electrical crossover handle the midrange and treble, characterized by remarkably natural intonation and a timbre with minimal sharpness. The electrostatic dual driver is the cherry on top, providing an extraordinary sense of ultra-high frequencies.
We have also improved the SES™ (Space Expanse System) technology you love in the Craft Six. We specially tuned it for electrostatic drivers and invented the patent-pending SES™ 2.0, our own field-specific, 3D-printed, horn-loaded tweeter. With the EST driver, we achieved unprecedented loudness and extension while maintaining its speed and softness. Now the last octave is exceptionally clean and refined, as never before.
Craft Ears Aurum also features our True LoadTM technology. It ensures an extremely flat impedance and phase, achieving great coherence between three different drivers.
