Craft Ears are a new CIEM manufacturer spearheaded by Jedrzej, a drummer, music composer, and producer from Poland. The company has been in the works for 2 years with the goal of creating the best sounding and most comfortable CIEMS for musicians and audiophiles alike. Craft Ears are a well-known name on musical stages over Europe and are focussing on their presence in the audiophile community. Jed utilises Sonion balanced armature drivers with custom sound chambers and offers full graphics personalization enabled by his adoption of DLP 3D printing to create shells. He has some very unique designs built to an immaculate finish. All CIEMs are covered by a 60-day fit warranty, 2-year warranty on components and life-time support. He is working alongside top engineers to deliver cutting-edge acoustical developments. I recently received the Craft FOUR for review and it shows great promise, impressions below with a full review coming soon!

Argentum
Argentum is one of our sibling models of the Genesis series created with "less is more" philosophy in mind. We put quality above quantity which isn't popular in mid range models. Precise implementation of one unique dynamic driver and carefully selected two balanced armatures from Sonion help us achieve sound quality above the price of Craft Ears Argentum.
Craft Ears Argentum is the evolution of our multiple times awarded Craft Four you loved so much! It is our second hybrid design from the Genesis lineup. Sound presents extended and defined sub-bass with a visceral impact, clear and well-textured midrange, and treble tuned to be as transparent as possible for a unique detail experience. Craft Ears Argentum features a dynamic, precise soundstage and imaging that can really do magic.
For low-end and lower mids, we have decided to go with a 10mm Carbon dynamic driver. It provides a faster, deeper, and more controlled bass with a more exciting signature. The sub-bass is incredibly extended. We have redesigned drivers and crossovers from our bestseller - FOUR - to make mids less sharp and increase detail reproduction, providing natural tonality. Super-Tweeter connected with carefully calculated horn structure provides clean and refined treble with adequate brightness and great soundstage.
The Craft Ears Argentum represents outstanding value. It is fun, but still a reference, musical earphones with punchy, extended low end, neutral, rounded mids, and precise highs.

Craft Six
The Craft SIX, creates the perfect balance - audiophile neutral and smooth sound with excellent dynamics and lifelike imaging. Featuring six drivers: Dual Sub-Low, Dual Low-Mid, Single Mid-High, and One Super-Tweeter, along with our proprietary RASEN Bass, True Load, and SES technologies.
Our six-driver earphone was designed to deliver neutral sound, with perfect balance, redefined low frequencies, and smooth but detailed trebles. Clear, big sounding, lifelike bass meets full-body and organic mids, all completed by smooth, extended, detailed but never harsh highs. The highest resolution, extreme depth, very wide soundstage, and surprising dynamics is something that makes our C6 model stand out.
C6 delivers Reference and Natural sound with highest calculations done to fully control Frequency Response and Cumulative Spectral Decay (first time in the IEM industry)
RASEN Bass ™ (Reference Acoustic Spiral Enhanced Bass) - Patent-pending solution, precisely calculated and designed 3D printed structure, that creates low-end notes as realistic as a true subwoofer.
True Load ™ - Extremely flat Impedance and Phase.
SES™ (Space Expanse System) - Our very own field-specific, 3D printed, horn-loaded tweeter which was tuned in a very particular bandwidth.

Craft Ears Aurum
Craft Ears Aurum is the pinnacle of our work till now and the highlight of the Genesis Series. It’s flagship model so there couldn’t be a better name than “aurum”, which means “gold”. Especially, as characteristics of this element, like natural shine, were our inspiration to create Aurum’s exclusive design and sound signature.
Aurum is our first tribrid model equipped with a specially ordered dynamic driver, four carefully selected armature drivers, and two Sonion electrostatic drivers. Our proprietary technologies make it possible to set new standards for IEMs with three different types of drivers. Thanks to that Aurum provides exceptional extension on both ends, excellent coherency, a huge soundstage, precise imaging, and remarkable detail retrieval, yet sound always is natural, smooth, and well-balanced. Meet the Genesis of immaculate sound.
Craft Ears always want to push the boundaries further to get the best sound possible. Our goal is to create something new and fresh. Aurum is our first tribrid IEM released as we believed that three different types of drivers allow us to create extraordinary and strongly technical sound, yet with great timbre and tonal balance.
Craft Ears Aurum is well-balanced IEM with great tonality and jaw-dropping extension on both ends. Its foundations are very deep and visceral, yet precise sub-bass and controlled, textured and impactful midbass. Each lower note is delivered with great attack and send of power, but never overshadows other frequencies. Mids are neutral and very detailed, yet have a good body and are smooth. Thanks to that, vocals could shine and easily reproduce an artist's emotions.
Highs are part of Aurum's sound we are especially proud of. Very detailed, yet smooth with good reproduction of cymbals. The extension could be compared with much more expensive IEM. It leads to a very airy presentation and great soundstage width. Aurum provides a sense of depth, precise imaging, and holographic feel with strong channel separation. Our flagship is a perfect mix of technicalities, naturalness, and musicality.
The exceptional sound of Craft Ears Aurum is possible not only thanks to carefully selected drivers but also our own technologies.
We decided to go with a 10 mm PEN Dynamic Driver that works as a true subwoofer. It provides clear, fast, and full, but not overwhelming sub-bass. Lightweight yet stiff PEN diaphragm coupled with N35 magnet makes lows unmatchable - accurate dynamics and exquisite sound quality all at the same time.
Four Balanced drivers with carefully chosen five-way electrical crossover are responsible for mids and highs, making them defined with remarkably natural voicing and timbre with minimal sharpness. The Dual Electrostatic driver is the icing on the cake, which gives an exceptional sense of ultra highs.
We also improved, the beloved by you in Craft Six, SES™ (Space Expanse System) technology. We have tuned it, especially for electrostatic drivers inventing patent-pending SES™ 2.0, our very own field-specific, 3D printed, horn-loaded tweeter. We have reached the EST driver's loudness and expansion never seen before, maintaining its speed and softness. Now the last octave is exceptionally clean and refined as it was never in the past.
Craft Ears Aurum also features our True LoadTM technology. It ensures extremely flat Impedance and Phase, which helps in achieving great coherency between three different types of drivers.
