The Omnium is the latest model from Craft Ears, which is also the new flagship. After I recently tested my first custom IEM with the Bellos X4 and was so impressed with the comfort, I also decided to go for a custom with the Omnium. After several personal messages with the very friendly CEO Jedrek from Craft Ears, I decided on the "Blue Galaxy" design with the colors silver/white, black and blue. After sending the digital ear impressions in the form of .STL files and after a processing time of approx. 2 months, I finally held my custom Omniums in my hands. Before I talk about the design, comfort and sound, I would like to shed some light on the technology behind the Omnium.
The Omnium was developed for both professional musicians and discerning audiophiles and is therefore intended to cover both areas. At the heart of achieving this goal is a very special driver setup that is rarely seen. A single 9.2mm DD driver is responsible for the bass range. A 10mm Planar Magnetic driver is responsible for the mid-range to ensure an even more natural reproduction compared to the use of pure BA drivers. The upper mids are supplemented by a BA driver. Another two BA drivers are used for the treble range. But that's not all. Another two BA drivers are used exclusively for the super high frequencies. So let's add them up. So the Omnium uses a total of 7 drivers with 3 different technologies. I'm particularly excited about the integration of the Planar Magnetic driver. I'm only familiar with the PMG Audio APX (although I haven't heard it yet), which also uses Planar Magnetic drivers, in this case two of them. Perhaps we will see this more often in newer IEM models in the future if it has a positive effect on the sound. Developments in the IEM sector therefore remain very exciting!
I would also like to mention two further developments from Craft Ears that have found their way into the Omnium. One is the "True Load" technology. This ensures that the Omnium always has the same frequency response on all DAPs, regardless of the output impedance. SES 3.0 (Space Expanse System), a sophisticated audio enhancement technology that takes the listening experience to a new level. The SES is described as a special 3D-printed horn-loaded tweeter that is meticulously tuned for precise bandwidth. Craft Ears has ingeniously positioned the tweeter at the tip of the nozzle to enhance its presence, while incorporating a special chamber to regulate its output in relation to the other drivers. Finally, a 6-way crossover network ensures that all the drivers are combined into a single sound. More on whether this succeeds later.
The Omnium's precision and meticulous construction consists of a 3D-printed housing that not only ensures durability, but also contains special waveguides to optimize sound reproduction. The result is not just an audio accessory, but a true masterpiece that offers something not only for the ears, but also for the eyes.
I enthusiastically opened my package after the Fedex letter carrier rang the doorbell. The Omnium and all the accessories are in a plastic case. In terms of dimensions, everything fits in easily. I prefer this case to the round leather cases that offer little space. There is a sticker on the lid of the case with the serial number and the owner's name. The scope of delivery includes a silver-coated OCC copper cable that can be operated differently using two interchangeable plugs in the form of 2.5mm and 4.4mm. It has a length of 1.5m and is therefore slightly longer than that of many other manufacturers (usually 1.2m). The cable is well made and very soft. I can't hear any microphonic effects. The scope of delivery also includes some stickers, a letter from the CEO and founder Jedrek Nowicki, a cleaning brush and a cable clip. All in all, the unboxing experience is rather unspectacular. The main focus here is on the essentials and that is the Omnium itself!
My custom Omnium is incredibly well made and looks fantastic! Well, blue is also my favorite color and that's why I chose this design. But Craft Ears also offers a lot of other designs. There is certainly something for everyone. The fit really is absolutely perfect. Screwing the IEMs in and out is child's play. They sit bombproof. On the first day you can still feel that there is something in the ear canal, but this gets better day by day. What I also noticed is the very high level of isolation from external noise. I've never had an IEM that isolates so well. But the Omnium is also my first "ordinary" custom IEM. I got my Bellos X4 Custom some time ago. However, due to the In Air Canals technology, it doesn't sit nearly as deep in the ear canal as the Omnium Custom does. As a result, the insulation of the Bellos X4 is not quite as high as that of the Omnium. However, the Bellos X4 is more comfortable due to the fact that you no longer feel anything in the ear canal. But no other custom IEM will be able to compete with it. Perhaps the Fir Audio E12 Custom, which has a similar design to the Bellos X4? I'll be testing that one soon too. In any case, I'm glad that my digital ear impressions seem to have turned out great and that I can use them for any subsequent custom IEMs without any problems.
For the sound test I use my two DAPs iBasso DX320 MAX Ti and FiiO M15s. I also use the Korg tube-based iBasso PB5 amplifier, which I operate together with the iBasso flagship DAP. The Omnium is absolutely easy to drive and with both DAPs you don't need more than the first gain stage to drive higher levels.
The most exciting question I asked myself after the comfort and the design is right, how does it actually sound? Tonally, it is a rather bright tuning with a touch of warmth in the mids. The bass is about 5dB below the usual Harman tuning. As I personally consider the Harman curve to be more bass-oriented, the Omnium's bass is neutral in my opinion. Neither the low bass range nor the mid bass range is emphasized here and the alignment of the bass has only one goal and that is quality! And here we really are dealing with a technically very good bass range that plays at a top level of quality. If the recording calls for it, the 9.2 mm DD driver can conjure up a hammer-hard bass curve in your eardrums. With thinner recordings like old 80s metal, however, the Omnium doesn't emphasize anything artificially and can come across as a little too thin. Personally, I would wish for 2-3dB more bass, like the AME Custom Gaia I recently tested. But that would probably affect the overall coherence and the audibility of the bass. With the FiiO M15s you can get a little more punch out of the Omnium than with the DX320 MAX Ti. However, the latter offers the more beautiful timbres. And in combination with the PB5, the punch is also quantitatively on a par with the M15s. Regardless of which of the two DAPs is used, modern metal recordings sound damn punchy and with plenty of texture. Once Upon A Time by Excalion or the new album by Rage are great fun. Ray Alder II is absolute madness with the Omnium! The 9.2 mm DD driver can do that really well without any support from BCD. But as I said, the Omnium wouldn't be my first choice for thinner recorded material like 80s metal or new wave.
From 200Hz onwards, the Omnium roughly follows the Harman curve with slightly lower upper mids and less presence. The mid-range with its sound colors is the biggest highlight of the Omnium for me. The Planar Magnetic driver conjures up a warm, full-bodied mid-range, which particularly highlights vocals wonderfully and provides a touch of tube sound. This is not the kind of mid-range that aims for maximum instrument separation, as is the case with an EE Raven, for example. Instruments play with more body and contour. But they are still placed extremely sharply in their space and can be located with ease. This Planar Magnetic driver produces an overall timbre that is not comparable with other IEMs that use DD or BA drivers. A Multiverse Mentor also plays with great timbre and fullness in the mids. Nevertheless, it is not comparable with the Omnium. Let me try to transfer this to the headphone sector. A Multiverse Mentor sounds comparable to a Focal Utopia 22 in the mids and the Omnium sounds more like a Susvara. The mids of the Omnium are spectacular for me!
The Omnium doesn't shy away from the treble either. The implementation with the two BA drivers for the treble and two additional BA drivers for the super high frequencies does a great job here. The Omnium is one of the TOTL IEMs with a very good treble range, which masters the balancing act between resolution and yet smooth reproduction fantastically well.
In general, the entire tuning from bass to treble is absolutely coherent and nothing stands out. And all of this at an absolutely top technical level. What more could you want! Yes, there are IEMs with even better treble like the Gaia or bass like the XE-6 or Raven. But an IEM with better mids? For me, the Omnium even beats the Multiverse Mentor here, albeit very narrowly.
The stage imaging is one of the more compact forms. It is somewhat wider and deeper than average (e.g. compared to the 64 Audio U4s), but is very well realized. As already mentioned, there is nothing to complain about in terms of separation and localization.
At a price of 2499€, I think the Omnium is an insider tip in the TOTL IEM range. In terms of tuning and coherence, it outperforms many candidates from higher price ranges. With a mid-range that will make any audiophile rave, the Omnium is one of the best IEMs currently available! If I could wish for anything else, it would be a sound switch with which you could increase the bass range by 3dB as required, then it would be a perfect endgame IEM!

Craft Ears is a very young Polish boutique brand founded in 2019 by Mr. Jędrzej, also known to his friends and family as Jed. Alongside his passion and lifelong for achieving the pinnacle of sound quality, the founder is also drummer, music composer, and producer. Like most prominent boutiques, Craft Ears already has a successful track record of making custom IEMs for musicians in Europe. The brand truly rose to fame in the the audiophile consumer sphere after releasing of the Aurum, a magnificent tribrid priced at $1384. They also offer the relatively affordable Argentum ($735) and “The One” ($845). Omnium is the current Craft Ears flagship, which has already garnered much praise from the summit fi community lately. Amplify decided to buy one to see what the fuss is about, and I must say, these positive statements are not honeymoon phase hyperbole.

Specifications
Omnium features a seven-driver tribrid configuration. A 9.2mm LST dynamic driver handles the bass, and a 10 mm planar driver handles the midrange. Five balanced armatures (one for high mid, two for treble, and three for upper treble) handle the high mids and upper frequencies.
According to Craft Ears, The Omnium utilizes a tubeless design with custom-tuned acoustic chambers and resonators. Combined with their innovative SES 3.0 (Space Expanse System) and True Load (Flat Impedance) technology, this guarantees a wide soundstage and consistent performance across different devices. These sound like a mouthful, but they work perfectly as described which I will discuss in detail in the sound review.
Build quality, accessories, and comfort:
Omnium looks and feels exotic from the get-go. The faceplate is made of carbon fiber (not a fake texture, but actual carbon fiber), with a gold-plated Craft Ears logo and a gold-plated edge lining surrounding it. The rest of the earpieces are made of 3D-printed resin, which is finished so well that I initially mistook it for ceramic (ceramic would make the earpieces too heavy, so that makes sense). Build quality and aesthetics-wise, I have nothing but high praise for the Craft Ears Omnium.
The outer package might look small for a ToTL set and somewhat spartan, but the color scheme and font placements are tastefully done and exude quality. The accessory package seems sparse at first glance, but every single one of them is functional. Craft Ears provides a heavy-duty pelican-style hard case, which is the perfect size for the IEMs, in my opinion, neither too small nor overly large. A generous selection of ear tips is provided in a Craft Ears printed small plastic box. The modular stock cable that comes with the packaging is of fairly decent quality and ergonomics, though you can always switch to better cables.
Unlike many of its flagship IEM counterparts, the nozzle is not overly thick, making experimenting with different sets of tips a breeze. Though the earpieces are slightly large and hefty, I had zero issues regarding comfort thanks to the overall flatter profile and ergonomic contours. The nozzle is angled aggressively and burrows deep into
the ear canal. It might take a few days to adjust for folks accustomed to shallower fit. Isolation was fantabulous for me, thanks to the deep fit and seal I got with the stock dual flange tips. Fortunately, there is no ear pressure build-up or driver flex.
Sound
The Omnium is one of those rare IEMs that immediately makes you blurt out, “Whoa, it sounds great!”. No steep learning curve, wow factor, or acquired taste is involved. That is how effortlessly pleasant and natural this IEM is from the get-go. Its timbre somewhat reminds me of the fantastic DITA Perpetua and Aroma Audio Jewel in many ways.
"FR Measurement by @aaf evo"
Tonally speaking, I would describe the Omnium as a mildly V-shaped, hyper-balanced set without any focused emphasis on a particular frequency. The bass is present and textured, with a nice balance between the sub-bass and the midbass frequencies How solid and prominent this bass would perform is greatly source sensitive though. The bass was incredibly dense, tactile and enveloping when paired with the Sony WM1ZM2 + Aroma Audio A100TB while with the iBasso Osprey PB5 portable amp it was more subtle and sub-bass focused. With the Questyle CMA 18P the bass response was somewhat similar to the PB5 but with a bit more midbass tilt. Determining what source you would pair this IEM with for the optimal bass is crucial. I thoroughly enjoyed the Aroma A100TB combo for hip-hop and aggressive tracks. What's Ya Phone Number? by 2Pac and Skin of my teeth by Megadeth are two great examples. For slow-paced tracks and orchestral music, I preferred the PB5 pairing slightly more.
The midrange is easily my favorite aspect of Omnium. It is precisely how I envision a proper midrange rendition: neither too dense nor too glassy, with extreme precision and background nuances that pop effortlessly. The midrange here strikes the perfect balance between clarity and heft. The vocals are pure bliss to listen to, be it the thick, manly voice of Johnny Cash, the distinctive falsetto-fueled voice of Supertramp's Roger Hodgson, or the high-pitched, angelic voice of Joni Mitchell. Omnium’s midrange is clearly on par with the midrange of Aroma Audio Jewel and DITA Perpetua, if not better.
Omnium is not a treble-head set per se, but I find it sufficiently airy without any hint of sibilance of grain. It has a very rounded, safe treble rendition that makes even inferior recordings tolerable while retaining all the information. Under $3000, Flipears Aurora XXIV is the only IEM that I can think of that does this. Like the bass response, Omnium's treble is also tied to what source you are going to pair it with. I was astounded by the level of transparency and air in the treble region, which had zero trace of unruly zing. The FATfreq Grand Maestro also does a similar thing with the treble and actually pushes even more air, though I find the slightly richer vibe of the Omnium more suited to my taste.
Omnium is a spectacularly technical and coherent IEM despite its non-offensive approach. Thanks to its pitch-back background and extreme micro-contrast and detail retrieval capabilities, I can pick apart small background nuances from each instrument without putting in extra effort. The soundstage is more expansive than average and very three-dimensional, simultaneously; it images with pin-point accuracy as expected from a brand with pro audio pedigree. The Omnium has a very accurate studio monitor 'esque approach in terms of positioning. Voices and instrumental notes that are supposed to sound intimate sound intimate, and vice versa. It sort of reminds me of the Hifiman Arya Organic in this regard.
Another thing I love about the Omnium is its equal excellence across genres and applications. Its safe but not overly so approach makes it a perfect IEM for gaming, movies, and intense audiophile listening sessions.
Comparisons:
64audio Volur:
The Volur is also a quite organic sounding by 64audio standards. It has more bass, but it is not the type of bass I vibe with. It's relatively softer and more diffused for my liking. A bit more tactility was what I was missing dearly when listening to the Volur. Volur is also way more intense and forward in the upper treble, though not sibilant, potentially causing fatigue in long listening sessions. I do like the Volur on its own, but for the same price, Omnium is a clearly superior set.
DITA Perpetua:
Perpetua is the best single DD IEM to date and the emperor of timbre and soundstage. That being said, Omnium’s timbre is almost equally as good. It's markedly more technical, way more technical, in fact, while the Perpetua is more of a $1500-2000-level IEM in terms of sheer resolution. Perpetua has a more natural and realistic bass decay. Midrange timbre and transparency are about equal on both. Perpetua is a very unique IEM that is really in a niche of its own. A great compliment to the Omnium, in my opinion.
Flipears Aurora XXIV:
Aurora is a bass canon compared to the Omnium. It is smoother-sounding and has a lush, warm sound signature, while the Omnium sounds more forward and crystalline in comparison. Technical performance-wise, they are equals. Aurora has more of a ZMF Atrium type of presentation, while the Omnium is more along the lines of ZMF Caldera, if that analogy makes any sense. Omnium has a blacker background, and subtle undertones are easier to discern on it than the Aurora.
Fir Audio XE6:
XE6 is a heavily colored set that requires acquired taste to appreciate. I personally find it awesome and insanely fun. XE6 has wild, untamed bass with a strong midbass focus, while Omnium's bass is more civilized and subtle. Thanks to its heavily colored tuning, XE6 is also more genre-specific. XE6 is a great addition to a collection of ToTL IEMs, but if you have the budget or willingness to keep only one, then Omnium will be my suggestion.
FATfreq Grand Maestro:
Grand Maestro is another fantastic all-rounder that I dubbed as a "Maestro of All Trades" in a separate review. Maestro is more U-shaped than the Omnium, with a higher bass shelf and a more lifted air frequency range. Omnium sounds comparatively richer and weightier, especially in the midrange. The level of transparency and resolution is about equal on both. Grand Maestro has a slightly larger soundscape than the Omnium, which is comparatively more intimate.
Craft Ears Omnium is a true master of all trades in a ToTL crowd filled with specialist sets. A no-brainer if you want only one ToTL IEM that performs at its peak in every genre. Omnium highly rewards different sources and cable combinations as well which is a big plus in my book. It is an IEM that genuinely does justice to its “Omnium” moniker.

Great review! I am a huge fan of the Omnium and opted to buy them as a CIEM for myself after owning them in universal. However, if you are going to use my measurements for your content I would appreciate being credited for them.
