Craft Ears Omnium Review ​

Intro​

Hello, this sound review and feature covers the latest from a truly premier audio brand named Craft Ears, and the set I’m referring to is the Craft Ears Omnium. The Omnium ($2,600) has a very unique tribrid driver configuration (1DD, 1PL, 5BA’s) and to say I was excited to hear how Craft Ears implemented those drivers is an understatement. Craft Ears has a long history now of producing some of the finest earphones on the market. Granted, this is the only Craft Ears product that I’ve had the pleasure of spending time with. However, I’d be lying if I said I wasn’t more than thrilled to be able to spend time with this set and explain my thoughts about it. I should also note that I received the Omnium as part of Audio Geeks United States review tour. So, thank you very much Audio Geeks and thank you Craft Ears. Truly, when it comes to spending my quality time with the Omnium in my ears… the pleasure is all mine!

Craft Ears​

If I’m being honest, I really didn’t know much about Craft Ears previous to a couple years ago. I’ve seen their extensive website and checked out their products, but with three kids, a mortgage, and a bunch of other things which drain my money I simply don’t have the funds to attain any of those fine products. So of course, I look from afar, nod my head, looks amazing … maybe one day. It wasn’t until Audio Geeks made this feature possible that I began checking out Craft Ears origin story in greater curiosity. It took no time to be impressed folks. The Craft Ears journey is a cool story. The brand was conceived only in 2019, out of Poland. That’s going on six years ago. I had no idea. However, this brand was born from the passion of one man. This man goes by the name of Jedrek. A musician, drummer, music producer, with a background in engineering and apparently, he’s also a very talented and outgoing person. Craft Ears has a series of videos in their “About us” section of their website which explains this origin story, spoken by the man himself. Years ago Jedrek decided that he’d simply craft and create iems for himself and after much trial and error he began to hit his stride. Thus, in a very condensed format, Jedrek founded Craft Ears. At any rate, it’s fairly obvious that Craft Ears has some extremely talented people and a penchant for creating not just iems, but works of art and passion. I couldn’t be more impressed. By the way, I shortened this story so much that it’s almost criminal. I can tell you for sure that I am most definitely a fan now. How could you not be?

Without further ado…
Folks, I am thrilled to be able to spend good and quality time with the Omnium. I have nothing on hand for a good comparison, but I have two ears and an interest in providing you the best explanation of the Omnium, to the best of my ability. With all of that said, I think I’m ready to get this review going. So, without further ado, the Craft Ears Omnium everyone…
*Note: I need to note that this review is only a “sound review” as I did not receive any of the packaging or accessories involved with the packaging. The only thing that I received was the earphones themselves as well as the beautiful cable. I can only speak on what I experienced firsthand.

Build / Design / Internals / Fit ​

Build Quality ​

The Craft Ears Omnium is simply built wonderfully. Enough said. I find the Shells to be very intricately crafted with precision as Craft Ears used a special 3D printing tech to create the housing of the Omnium. The faceplates have a slick looking carbon fiber design with polished acrylic resin covering making a very well developed and totally unique look. The nozzles actually have a slightly deeper fit than average yet is built to a perfect angle for my ears. I mean perfect! I couldn’t get a better seal. At any rate, the Omnium is built in a stellar fashion which exudes durability. It’s something you feel when they’re in hand. Very nice in its structure. I don’t see any extra ventilation holes. No where on the front or the back. That said, I also don’t get any annoying suction issues either. However, what this build style does accomplish is truly awesome passive noise isolation. Craft Ears states in their promotional material that the Omnium will afford you at least -26 db’s of isolation. That’s pretty awesome, if you didn’t know. Great for on stage and casual listening as well with no sound leakage. Folks, the Omnium is a structurally sound set with adequate weight, and certainly bulky. Still, I think this set is made with attention to detail and with strict scrutiny over the whole process.

Design​

Now, the design is one which is an actual art piece. The colors, the contrast, the materials, they all come together to form one of the better looking iems out there. Now, nothing is for everyone, but I cannot imagine many folks who wouldn’t feel that the Omnium is one of the sleeker looking iems on the market. Like I said earlier, you can actually change the design to fit your preferences with many options at the Craft Ears website. That said, I’m only speaking on the standard model here today, naturally. Still, the standard model is absolutely gorgeous! Again, it has a carbon fiber faceplate design with a high polish imported resin coating while an 18k gold border encircles the faceplates. Each one meticulously made, by hand, from a team of folks with more than 10 years of experience. Friends, hear me out. My pictures do not do this set justice. I tried, and I tried hard to capture the fibers in the faceplates, or the black-on-gold colors distinctly coinciding to form what I’d consider a small work of art. It’s just clean, from front to back. Basically, when the Omnium is in hand and in the ear you can see with perfect clarity what it is that you are paying for.

Internals​

This brings us to the Internals within the Craft Ears Omnium. I have to be honest, one of the largest reasons why I even wanted to hear the Omnium was because of the elaborate driver configuration. Again, the Omnium has a tribrid setup with a total of seven drivers separating the frequency by way of a 6-way crossover. Before I explain the drivers, I’ll first mention that Craft Ears employed their very own trademarked Space Expanse System named SES 3.0 as well as their own trademarked True Load “flat-impedance” technology. Friends, I really tried to find out more about this tech but there isn’t much that is readily available. However, one of the cooler things is that the Omnium presents a tubeless design along with what Craft Ears calls “custom-tuned acoustic chambers and resonators”. Needless to say, this type of internal structure obviously requires prolific engineering and understanding of acoustic principles. They did the work, and we benefited.

Drivers ​

Back to the drivers, Craft Ears decided to go with seven drivers in total using three different types of driver tech. They went with an amazing 9.2mm LSR (liquid silicone rubber) dynamic driver to cover the lows. LSR drivers are known for their bone rattling dense bass and impactful, punchy qualities when well implemented. I’ve tried a few other sets using LSR drivers and the Omnium is clearly the best. Next, Craft Ears went with a 10mm planar magnetic driver to cover the midrange. This is the one I was curious about the most. For the upper-mids they used one balanced armature driver. I have no idea what make and model of any of the BA’s. The highs use two additional balanced armature drivers, and the upper treble is also covered by two balanced armature drivers. So, as you can see it’s a pretty eclectic mix of drivers which encompasses this tribrid set. I should also mention the complexity involved in crafting a set with this many drivers, different styles and types of drivers, and doing so in a coherent manner harmonizing all of the qualities of each driver. This is no small feat folks. The people of Craft Ears should feel proud over this one. They sound fantastic!

Cable​

I should also speak on the cable provided with the Omnium. After all, it’s the only accessory that I have at my disposal. Having said that, I know almost nothing about this cable. Other than the fact that it is in fact a 2-pin cable with a 4.4 balanced termination, it’s 1.5 m in length, and the cable is made using silver-plated OCC copper materials and gold-plated jacks. As far as materials used, that’s all that I know. As far as the look; it’s a nice cable. The Omnium deserves a quality cable. I wouldn’t say it’d be my first choice, but a nice cable, nonetheless. So, it’s a copper-colored cable which actually looks great when paired with the Omnium. I feel the PVC outer insulation is pliable, rolls up nice, isn’t microphonic to my ears either. Not bad at all. I used this cable for about half of my critical listening. However, I also decided to upgrade the cable using an Effect Audio Eros S ii (series 2) cable just to hear if there was a slight difference. The sound using the Eros S ii was a small upgrade which seemed to fit the Omnium very well. That said, the included cable is perfectly fine and does exactly what it’s supposed to do. Again, it wouldn’t be my first choice, but if I was stuck on an island alone with my dap, the Omnium, and the included cable… I’d be perfectly happy. At least until my battery died. Not bad at all.

Fit / Comfort ​

As far as fit and comfort is concerned, you have to know that I have zero idea how this set is going to fit you. I’ve said this in every past review and it’s just as relevant now. As for me, the Omnium literally couldn’t fit better. I don’t have big ears either and the Omnium is quite chunky. Be that as it may, the nozzles have the perfect angle which seats wonderfully in my ears. I get a nice seal everytime and the bulk of this set isn’t a concern at all. Yes, this set is big, and yes, the fit is deep, but the ergonomics of this set is very good, for me. Obviously, the comfort is also very nice. I’ve had many multi hour sessions and never once did I get irritated with how the Omnium fit my ears. So, it’s subjective and we’re all different, but I really feel that the majority of people will have zero issues, just like me.

Drivability​

Output Power ​

Friends, I looked everywhere but I was unable to find an actual sensitivity of the Omnium. However, I was able to conjure up the rated impedance which is right around 12 ohms. I suppose the sensitivity numbers aren’t all that important because I thankfully have my ears to guide me. From all of my sources I honestly never had an issue. Even less powerful sources worked just fine. However, folks, this set deserves and desires some good and strong output from whatever device it is that you choose. Without question! Feed it some power. I promise it will reward you. Also, how many people are buying the Omnium at $2k without also having a quality source? It’s almost a crime to pair a dongle dac with this set, but lo-and-behold… they actually sound fantastic when I used the 4.4 balanced port on my devices like the EPZ TP50, Aful SnowyNight, and about 15 others that I’m not willing to jot down here. I mainly used my Fiio Q15 on high gain, my Shanling M6 Ultra (also high gain), as well as a few other daps and it is very apparent to my ears that power brings out the best in this set. Now, it doesn’t have to be 10,000 watts but give the Omnium some juice. You can thank me later.

Source Pairing ​

As far as tonal pairing of the Omnium with my source devices. After listening to over 20 different devices in the time I’ve had the Omnium, I personally enjoy a warm/neutral to neutral source device. Now, the Omnium is just that… warm/neutral. Or, mostly neutral with an ever-so-slight warmth captured within its tonal coloration. That said, I absolutely adore this set with my warm/neutral Shanling M6 Ultra. Just wonderful. Something about how crisp this set can sound, how clean-lined it is, and how utterly spacious the stage is that having a warmer source didn’t exaggerate whatever warmth the Omnium is perceived to have. No veil, nothing blended or too congested sounding either. In truth, I found the Omnium to mesh very well with most sources. Please take note that the Omnium really does have some significant changes per what source you do choose. Now, I don’t think it’s very “picky”. Meaning, the sound will truly be great no matter what you choose. But it will adapt to the source and you will have tonal changes, so I’d choose the source which fits you. One more point, I would certainly try to pair the Omnium’s with your best sources. No doubt this is a set that will reward you for feeding it with cleaner and more sonically gifted devices.

Sound Impressions ​

*Note: I mentioned it in the intro but I’ll mention it again, the Omnium came to me from Audio Geeks USA Tour provided from Craft Ears. What this means is that I received this set after many folks had already had a chance to listen. I say that because I have zero idea if burn-in is necessary, or not. Sorry for that. Also, I listen almost entirely with flac or better files which are stored on my devices. I mainly use UAPP (USB Audio Player Pro) as my Android music player as well as occasionally use Hiby Music Player as well.

What’s it sound like? ​

The Craft Ears Omnium is truly a special iem, from so many angles. Every way you turn the Omnium you’re actually seeing the epitome of the word “premium”. Luxurious in how it’s outfitted, upmarket and upscale in every way. However, brush all of that aside. Folks, if it doesn’t sound good then everything else is a golden ring in a pig’s snout. One thing I found out right away is that the Omnium absolutely fits the bill of a flagship caliber iem from a flagship caliber brand. The type of set which reminds those who berate companies for their kilo-buck offerings that there is in fact… levels to this game. Make no mistake friends. Without question the Craft Ears Omnium is one which resonated to the umpteenth degree with me and one which I have taken every second that I’ve had to engulf myself in its sound. After all, it isn’t every day that I am able to hear a set of this quality. I’m going to get the most of it.

Well represented ​

In my opinion the Omnium hovers right around warm/neutral and comes across in a mostly speckless manner (for the tuning) and a very full sound with a smoother demeanor. A subtle warmth evokes a certain organic quality that the Omnium has. It’s a realistic tinge towards the natural. Authentic in its timbrel approach and aided by a holographic, almost euphonic stage showing off every front to back tier of sound that my music asks of it. Somehow Craft Ears crafted this tribrid set with the cohesion of a single DD, yet with the fairly clean-cut separation, depth of field, and distinct note outlines of a multi-driver iem. Basically, every solid quality of every driver used in the Omnium is tailored wonderfully to the target that Craft Ears was shooting for. Add to that, every area of the mix is well accounted for and very well represented. I’d say the Omnium is a nice mix of technically able and musically inclined. It’s a very smooth operator through and through, yet doesn’t lack the knife-edged definition needed for certain tracks, certain instruments, and overall note definition when a track requires it. There’s plenty of upper frequency brilliance to illuminate the subtle details, with some caveats that I’ll explain later. Maybe not the most exciting set on planet earth but man does it have its rewards.

Super condensed sound between the 20’s​

I’d say the Omnium carries a U-shaped sound signature with a focused sub-bass lift and again, a fairly brilliant upper half of the frequency. The sub-level of the bass is an absolute banger! It hits hard! Deep! The mid-bass is more slender and not as impactful but has enough boom for most genres. One thing is for sure there is no shortage of texture, and it comes across very well contoured and clean. Now, the midrange is dynamic, pristine, lean in body but dense in perceived mass with a clean contour to notes and never really recessed to my ears. The mids are forward, snappy, yet not without some form of musicality. Each midrange note has good clean-lined presence, leaner in body but still rich. There’s authority in the midrange presence, the lean density. The Omnium also has better detail retrieval than I would’ve guessed and does so with the help of tight transients, a glass-lined surface texture, along with a widespread, tall, deep, but also fairly intimate stage. Separation is nice, Imaging is spot on and I hear fantastic layering of sounds. In fact, that’s one of my favorite aspects of this set.

Bass Region​

The Omnium is not basshead. Let’s just get that out of the way now. I’m sure if Craft Ears wanted to they could produce one of the most amazing basshead sets on the market. However, the Omnium is not it. Now, this set is certainly “partially” tilted that way as the sub-bass has a mean lift with plenty of emphasis enforcing the lowest of the lows. In my opinion the Omnium is just above moderate in its low-end muscle with a densely weighted sound down low which can get flat-out jarring when a track calls for it. Now, the low-end mostly keeps to itself. This is not a bass region which enforces its warmth and weight to every far corner of the frequency. Craft Ears is better than that folks. What they did was roll off the mid-bass just enough to leave pristine mids. In fact, the bass flattens right at about 150hz. Having said that, this somehow doesn’t take away from the mid-bass boom as I thought it might. Perhaps on some big bass drops I could use more oomph and boom muscle as the lows are missing just a touch of impact due to the roll-off. But I really wasn’t missing much of anything besides those rare instances. The truth is, the low-end has plenty of body and meat for most any genre. Not to mention that the bass region as a whole is very well defined, very clean, and not even hinting at anything one noted or blended. I hear excellent texture, nice layering of the bass, and I can certainly feel the low-end rumble. So, it could use a hair of impact, and the Omnium may not be the mid-bass boom king. If those are the only downsides thus far then… I’d say the Omnium is doing pretty good.

Sub-Bass​

Like I said, the sub-bass region houses the most of the Omnium’s low-end emphasis. That said, I should prepare you for just how bone rattling this sub-bass can get. This 9.2 mm LSR driver was absolutely put to the test during my critical listening “bass playlist” and passed with flying colors. The sub-bass enforces its will on the track “Groove” by Ray Wylie Hubbard. Every undulating and quivering note is met with some of the deepest droning haptic growl that I’ve heard in a while. Really, the Omnium provides a very hardy and robust rumble and vibratory feel to my music. In the same breath, I hear a very streamlined cleanliness without the usual fuzz floating around at the crest of every note. Sub-level notes are hard edged, well contrasted, dynamic, and they can take on some very fast bass passages with relative ease. I fell for the mixture of mass and speed when listening to this set. How the driver can attack fast, hard, and with a concrete style note surface, full of dense meat, and then decay and recover with precision. Notes are rounded, well dimensioned, never flat, always full, never pillowy, and always clean. Really a nice job here.

Mid-Bass ​

Again, the mid-bass does have a slight roll-off, but somehow, I hardly ever miss whatever it is that it’s supposedly missing. There’re a few tracks missing that last little bit of added weight in this region, but really the mid-bass still carries a decent boom. I’d say it’s very well put together. The mid-bass has very decisive and very firm notes with usually very explicit note outlines. Well defined, punchy too. Couple those descriptors with the aggressive sub-level palpable drone and what you get is a very well-rounded bass. Lucas Graham has a track called “All of it All” and right away the Omnium reminds me why I should never look at a graph. This is one of those tracks which calls on some meat in this region and the Omnium delivers. However, it’s in tandem with the presence from the sub-bass which almost bolsters this region. Or Sun June in the song “Everything I Had”. Right at the outset of this song you’ll hear the bass guitar’s fullness. It bellows, pregnant with a low drone yet concise at the edges. No extra fat at all. Lean, yet dense. If that makes sense. There’s an organic depth and timbre along with a natural decay that creates a very atmospheric sound while at the same moment that full bass never seems to mask over other frequencies. Really a well-controlled bass in general.

Downsides to the Bass Region ​

Without a doubt the number one thing that you may want to watch out for is the sub-level emphasis. It’s hefty, meaty, guttural to the core. Not everyone desires such a sound. In the same breath, there’s almost a lack of impact at times too. Not every track either. However, I can attest that on some tracks you’ll feel as though you are slightly missing something. Very rare, very few and far in between, but it exists with the Omnium. Definitely, there will be those who want a more balanced sound, less coloration. However, with this sub-level emphasis I don’t hear any distortions, and it’s never so emphasized that it obscures other elements in the mix. I also wouldn’t go so far as to call it bloated either, It’s way too clean for that. To flip that coin, there will certainly be bassheads who actually desire more than the Omnium can give them down low. I mean, you have to be a bona-fide bass junkie, but they are out there. To finish this section, I just want to declare that I love this bass. For so many reasons and from many tracks. I love the speed, the bulbous body, the decisive and dense notes. Just really nice.

Midrange​

This brings us to the midrange. I hear a mostly warm/neutral midrange with a forward tilt, perhaps making the soundstage come across a slight bit intimate. Yet the stage also comes across wonderfully holographic with great layering of the sound field. As far as note weight goes, I’d probably refer to the midrange as lean-lush in its approach. Less like a milkshake and more like skim milk. It is milky though, with a silken sound and moist notes which never really come across “traditionally” thin, dry, papery, or anemic to my ears. I suppose the midrange is a hair lean, but somehow it does have adequate body across the mids due to the density of each note and the black background. Again, there’s a richness to the sound which is completely enthralling. Couple that with a very engaging and immersive soundstage presentation and what you get is a wholly captivating and charming sound. To add to that, Craft Ears was able to draw enough solid emotion from my music, with enough smoothness, and enough wetted body to keep from sounding analytical. Truth is, I could definitely use a hair more warmth to embolden the low-mids a bit more. But please trust me… I’m not complaining. After a few songs I began to melt into this midrange and all questions about warmth and note weight flew right out the window. This lean-lush approach is partially caused because the low-end really doesn’t encroach at all into the midrange, leaving a very pristine sound in this region without any chance at any veil or any muddiness in my music.

Mids cont… ​

Now, the Omnium midrange does borrow some vibrancy and crisp snap from the opposite end of the spectrum, leached from the treble region. Enough of a pointed and acute snap on attack for instruments such as snares, cymbals, adding that satisfying abrasiveness for strings with very nice harmonics. Generally speaking. Also brass or woodwind instruments have enough energy to never come across dull but rather pronounced and with great presence in the mix. Of course, not every track is the same but by-and-large the Omnium does sweet justice for most instruments. Also, the Omnium doesn’t have an ultra-contrasted and rambunctious presentation. Yes, it has good energy, but that energy is well regulated, well structured, never loose or sloppy and never too vivacious. It’s controlled, clean, and each note sounds cropped, trimmed, and shaped enough to pull nice separation of instrumentation along with plenty of air in this region too. Also, I don’t hear anything I’d call shouty, sibilant, or metallic, and the cohesion of the drivers is out of this world. Timbre leans natural to my ears with a nice attack and a natural decay to most notes. Resolution is pretty darn nice in this region too with good note definition, separation, and air to the sound. The Omnium is not tuned to be a detail beast, but in my opinion, it illuminates the subtleties very nicely. Really an all-rounder style which should fit many hobbyists quite well.

Lower-Midrange​

If I were to characterize the low-mids, I’d say “lean n’ clean”. Now, “lean” is not a downside in my eyes. Perhaps for lesser quality iems which come across more dry, papery, and less concrete in body. However, the Omnium is none of those things, but instead the Omnium presents stuff like male vocalists very favorably against the rest of the mix. They come across substantial in the face of that lean structure. You have this lean-muscle mass style of fast twitch transient behavior in a fluid manner with a smooth body, crisp at the edges, well defined, and nicely etched in the face of a black background. Can a set of earphones come across both lean, and… meaty? Well, I suppose they can. Is the greatest contributing factor the tuning, the drivers, maybe a little of both? That said, the low-mids do come across with a subtle warmth. Not a lot, but it’s there. They aren’t dead neutral. I’d say toeing the line closer to warm/neutral, yet with one foot leaning closer to the neutral side. Oddly enough, there is just enough warmth to give instruments and male voices a palpable sense to my ears. There’s texture in these low-mids while layered sounds project some dimension into my music. Notes have a certain roundness to them. Of course, I could repeat this same thing in every area of the mix. Another thing I think is great is how well Craft Ears tuned this set and all of its drivers to come across uniform and very cohesive. Every transition sounds nicely blended.

Low-mids cont… ​

I definitely hear an almost glass-lined inflection at the crest of most notes. For instance, “How it Feels” by Zayn shows off his hearty yet raspy voice. With the Omnium in my ears, the note edges of that rasp aren’t exaggerated. So easily his voice can sound almost sharp. Especially when too much vibrance is added into the equation. What I enjoy about the Omnium is that his vocals remain in control throughout and never lose the note outline. He sounds knife edged without sounding abrasive. He sounds illuminated in the midst of solid underlying density and a very focused clarity. Almost as though his (and many other males) vocals sound embossed, with great presence, and a certain governed vibrancy. Again, I could use a hint more warmth here and generally I feel that males and certain instrumentation benefit greatly with a thicker and more hearty sound. However, it’s almost as though I’m hearing my playlist tracks for the first time going through many male lead songs just to hear how the Omnium will portray these tracks that I know so well. I gotta tell you all, the sound is so clean, transients are rapid, quick in decay, without lagging harmonics blending surrounding notes within the sound field. What’s left is very bold fundamental tones and a more sculpted body as a whole. It’s hard to not be impressed with this one folks.

Upper-Midrange ​

The upper mids come across more forward than the lower half of the midrange mix, which is pretty much customary in most sets. The Omnium can at times come across with a hint of glare. I suppose this is from the quick and steep pinna rise. Having said that, I don’t mind it at all. Perhaps not perfectly natural but with a nicely energetic sound which almost sounds capped-off so as not to induce too much brightness and luminosity into this region. Just enough to add some sparkle to the upper-mids, some shimmer, some strategically placed luster to female vocalists and instruments. Now, if you are sensitive to a pinch more vibrance in this area than you may want to look at other options. As for me, I actually really enjoy how Craft Ears tuned this region. I hear a nice crispness, some crunch, and a very resolving sound which draws out every last little micro-dynamic and micro-detail. Transparent, well-resolved, clean-lined, and once again there’s a smooth underlying fundamental tone. Usually. Every track is different but for the most part the Omnium has a magical ability of being many different descriptors at once. The upper mids once again pull off a very full sound while keeping a leaner demeanor. It’s the way female voices and instruments sound well projected, impelled towards the listener.

Upper-mids cont… ​

Also, the Omnium doesn’t leave out the emotion from my music. Like the song “I Can Change” by Lake Street Dive. Friends, there is a fullness that resonates in a very lovely manner. Feather-soft at the outset of the song to resounding at the drop of a dime. Yes, there’s a pinch more outward radiance and candor, but I feel this helps to propel her vocals. Every intonation of her voice sounds both clinical and emotionally gratifying. Enough to not come across analytical anyways. Again, there’s still a large enough musical influence on the sound and enough body to her vocals. Every reverb & secondary harmonic of the acoustic guitar which strums alongside her vocals comes through crystal clear. Once more, depending on your preference, this region’s ear gain may just bring you right to the cusp of your tolerance, only to stop short of anything offensive. This rise adds a sense of air to the sound, some space, solid separation, and helps to illuminate those subtle details. You see, the Omnium is not one of those sets with forced resolution in an attempt to draw those subtleties to the surface, which usually comes across grating. The Omnium isn’t that at all. Everything is under control, every note is contoured, every last accentuation and modulation of her voice is form-fitted and moist, never dry.

Downsides to the Midrange ​

I could list a few potential issues that some may have. All subjective tuning preference stuff. Like, the midrange is not a very thick and lush sound and those who desire that warmly weighted and mass filled sound will not exactly get that here. Again, this set leans analytical and while its notes do have nice density, they aren’t thick. Also, the pinna rise will likely be an issue for anyone sensitive to it. There’s no shortage of folks who want a less vibrant upper-mid to lower treble, who get fatigued very easily. While I have absolutely zero issue with how Craft Ears tuned this region, I still know that there will be plenty who’d be better served checking out other sets tuned more to their liking. In truth, I find the upper-mids very tasteful and they really do well to highlight all the technical stuff very well. I could also say that the Omnium definitely has a “quasi-natural” sound. Almost there. Perhaps the drivers themselves and their outright ability (transient swiftness, speed) along with the slightly boosted ear gain keeps the Omnium from coming across perfectly organic. In my opinion I’d take this tuning every day of the week as it has way more wonderful qualities than anything else, but it isn’t perfectly authentic to life. Close though. I suppose I could also add that the sound is so clean and so precise at times that the Omnium will likely uncover the issues of poorly recorded and lesser quality tracks. This is one of those things that reviewers say, “audiophile speak”, but there’s some truth to it.

Tolerance​

Everything comes down to your tolerance for everything mentioned and your preferences. For me, I get lost in the sound of this set. The way it layers the stage, the 3D style dimensions of the sound field, the distinct separation, the wonderful cohesiveness, the nice mix of musicality and technical ability, the snap, the crispness, the controlled vibrance; It all adds up to a very compelling and completely engaging sound. You are getting what you pay for with the Omnium. Nice work Craft Ears!

Treble Region ​

The treble is one of nicely feathered-in brilliance and a very cohesive rendering of this region. I wouldn’t call the treble “energetic” as it comes across as slightly more calm, easy on the ears, less intense as a whole up top. Coming out of the upper midrange you have a quick dip at 6k in what most consider the “presence region” and then a linear ride on-out to the upper treble. Like I said earlier, you won’t have any of that forced-resolution which comes from boosting the treble region in an attempt to add more resolve, details, etc. What you usually end up getting is an artificial sounding treble with over emphasized peaks that usually end up causing fatigue. Not with the Omnium. Actually, I find the Omnium is tuned very nicely offering a smoother take on this region. Great for long listening sessions. I can tell you that the Omnium’s treble probably wouldn’t be the first choice amongst die-hard treble-bois. The Omnium simply isn’t tuned with the sort of emphasis and focus within the treble region that most treble heads prescribe to. That doesn’t mean it isn’t talented, very well defined, nice crispness, adequate treble bite, and solid extension though. Also, the treble still provides the rest of the mix with some solid air, openness, and levity, or luminance. Furthermore, the Omnium never sounds congested, or constricted, never dull and never boring. The treble simply isn’t boosted to the stars. Craft Ears made it palatable for the average listener and I can really respect that.

It fits the character of the tuning​

Like I said, the Omnium has plenty of edge to the sound which helps in adding some bite to notes but more than anything this is a smoother treble. The body to most treble notes is nice too and there is some tactile feel up top depending on the track or recording. Basically, just because you don’t have that ultra contrasted and dynamic treble doesn’t mean it isn’t a good treble. Craft Ears tuned the highs to fit the overall character and target they were going for. I’m sure if they wanted to craft and create the ultimate treble head set, they probably could very easily. It’s much harder to tune an easy going yet talented treble region. One where you still have very good note definition, treble punch, and a relatively brisk snap as on the Omnium. One which keeps a calm and linear path through the treble yet extends very well into the upper portions of the treble. Most definitely this region plays a supporting actor role, but treble is one of those areas which can literally make or break an iem. Too much emphasis, too little, lacks bite, too much edginess, too much sharpness, too dull. I could go on and on. The point is the treble is important to get right whether it’s the focus or not. I couldn’t praise what Craft Ears has done enough because the treble is dulled down yet still doesn’t lose the clarity, spunk, and resolution of a solid treble.

Examples ​

Furthermore, the treble has some speed too. Transients are not lagging at all. The treble can and will take on faster passages fairly well. As in “Magnetic Fields, Pt. 1” by Jean Michel Jarre. This track is littered with digital treble coming at you from so many angles. Very rapidly I might add. The Omnium is able to distinctly separate and delineate every attack edge with a layered and rounded note body with an acute incisiveness. For the most part anyways. Every note sounds very well placed in the sound field too. Timbre is fantastic as it isn’t overtly boosted causing anything to sound artificial. Enough brilliance to add some sparkle to each note in a more organic fashion. Very speedy too as I really feel that the Omnium almost forces my mind’s eye to locate every note. It isn’t just some mishmash of treble tizz blended and flatly displayed. There’s an element of dimension to the sound folks. Another track is “Evil Twin” by Lindsey Stirling. The Omnium is able to resolve all the subtle details in this less intense manner which is a nice thing to hear. So easily this track can push tolerances on lesser quality sets, with lesser quality drivers, and lesser quality tuning. Also, her violin comes across with just enough shimmer and dynamics to satisfy yet without becoming abrasive. Again, the sound field has layers to it with well placed notes. One more example is a track I also use often called “Ice Bridges” by Billy Strings. His banjo play is lightning fast, and the Omnium really does resolve this track well. Not every set pulls it off very well. Craft Ears did a fine job.

Extension​

Real quick I should write about one aspect of the treble which is surprisingly well done. That is, the way it extends into the upper treble. Folks, I am literally missing nothing out past 10k. The Omnium is able to convincingly portray every last lingering harmonic, every cymbal crash, or any other sound within the high-highs very well. Again, very nice timbre too. Now, every track presents cymbal strikes differently, but by-and-large I don’t hear anything splashy. I don’t hear anything with too much of a sheen to it. I hear cymbals with a nice body to them and the secondary harmonics seem to cut loose relatively quickly keeping a clean edge. This extension also seems to psycho-acoustically stretch the soundstage to a degree. I definitely get the illusion of greater width. I thought that was nice to hear as there’s a ton of info up top which many sets either neglect to capture or sound artificial to the ear.

Let’s face it… ​

Having said all of those nice things, let’s face it… there are certainly iems tuned to take on these areas better. However, at times those sets are more one-dimensional, while the Omnium is much more of an all-rounder style. So, it’s nice to hear such a talented sounding iem. Like a Swiss army knife of iems. Again, there are certainly iems which specialize in areas like the treble region. These sets can come across more resolving, with better detail retrieval, more tart in their note bite, and with more of a haptic feel to the treble region. So, the Omnium is obviously not perfect. No doubt this is a set which has to align well with your own personal tastes, and yes, I realize I made the most obvious statement ever right there. However, the sentiment remains. You have to want a slightly more laid-back sound tonally. You have to desire a less intense and less energetic sounding treble region. However, I really don’t want to skew these words in the wrong light. The Omnium is not without energy, dynamism, sharpness, and brilliance. It’s just like I said earlier, Craft Ears simply tuned the Omnium in a more palatable and easy-going manner.

Downsides to the Treble Region ​

No doubt the biggest glaring issue would be for treble junkies. The Omnium was tuned with more of a balance dynamically and so treble heads won’t always get that gratifying vivaciousness that they crave. Of course, for fans of good easy going treble, I have the set for you. I suppose the treble region could use a hair more of that pleasing snap and punch, similar to what you get with good EST drivers, among a few other driver types. However, I cannot take anything away from how this set was tuned up top. So long as you know what you are getting. Still its well detailed, good precision, has some zing, not too drab and not rolled-off to my ears. Also, the timbre is solid.

Technicalities ​

Soundstage​

The overall “perceived” size of the imaginary stage within my mind when listening to the Omnium is certainly above average. I’d say width is great, out past my ears, nice dynamic range, just as potent at the outer edges as it is closer to the center. You have decent height too, and very nice depth of field to my ears. Enough to put a smile on my face. That said, the Omnium sounds as though it is somewhat closer and more Intimate on the front end. The midrange is positioned a hair closer to the listener. I actually love this type of stage and prefer it to a stage which sits out in front, pulled back. I like the intimacy and so maybe I have a bias here. I’m sure there’s plenty of you who don’t enjoy a more intimate portrayal of your music. At any rate, for me it’s great and therefore I give it two thumbs up. Add to that the stage has a very nice 3D style dimensionality as well. I’ve said a few times that layering is very nice and that is partially due to the depth I’m referring to. I can tell you that the sound is not congested at all. The soundstage is great folks.

Separation / Imaging ​

Instrument separation is generally very good. The Omnium has that nice clarity, clean note delivery, well defined notes, it sounds airy and open, quicker transients, slightly leaner presentation. Add those all together and what you get (most of the time) is nice separation of elements within the imaginary stage. Of course, there are some caveats which should go without saying. That is, if you are listening to a heavily bassy track then you may get some masking happening. Obviously, you aren’t going to hear all of that good separation through that raucous bass. Also, badly recorded tracks are going to show themselves with this set and they may cause separation to not be as easy to discern. Imaging walks the same line as separation. Or better, as I find the imaging capabilities on the Omnium to be really great. I can’t remember any time during my listening that I felt anything was out of place. The Omnium is always on-point. Moreover, the Omnium’s layering ability is quite awesome too. Truly a nice set.

Detail Retrieval ​

As far as detail retrieval I’d have to say that the Omnium is above average. No doubt about it. For all the reasons that the Omnium succeeds in separation and imaging, it also succeeds in detail retrieval. Just a very clean sound as the Omnium has all the trappings of a set which can bring all the subtleties to the surface quite well. I hear nice micro-dynamics (depending on the track) and the Omnium has very nice and pronounced macro-details. For the micro stuff the Omnium performs much better when a track isn’t ultra congested and there isn’t a booming bass presence. I really didn’t have a hard time hearing the minutiae within my music and at times the Omnium is flat out amazing in this regard. That all said, I should also add that obviously there are sets which are tuned more analytical with a much more clinical sound which outperform the Omnium here. However, those sets also don’t have the wonderful tonality, timbre, and fluidity of the Omnium. This is why the Omnium is such a special iem. Really an all-rounder kilo-buck in-ear monitor that can mostly do it all very well.

Is it worth the asking price? ​

Okay, this question is going to have to come with some fairly obvious caveats. Let’s just get something out of the way, the Craft Ears Omnium is meant for who it’s meant for. Maybe that doesn’t make sense. Let’s try it this way, the Craft Ears Omnium is most certainly worth every last dollar of the $2k+ that it costs to those who have zero issue purchasing something at this cost. It is what it is. I’m assuming if you’re still here then you are likely one of those folks. The truth is, the Omnium is actually a very well priced iem for what it is. Yes it’s a kilo-buck iem, but against the current crop of kilo-buck sets it actually stands very tall. No doubt the Omnium will have to suit your idea of what “good” sounds like. However, at these prices I’m quite positive that you are well aware of what your preferences are. Anyone willing to pick up a top-tier flagship like the Omnium likely knows exactly what they are looking for. That all said, the Omnium has a big fat “YES” to the question in the header.

The Why… ​

Because the Omnium comes with an absolute boatload of accessories (I realize I didn’t cover the accessories, if I had them I would’ve.), a very nice copper colored cable, fantastic case, a slew of tips. Next, the build and design are so classy, very stoic looking, handsome, and premium in every sense of the word. Craft Ears gives you the option to design your own on their website with so many options that it isn’t even worth talking about here. You’d have to see for yourself. 18k gold trim surrounds the carbon fiber and resin covered faceplates. Folks, the design is absolutely DOPE! In every sense and meaning of the word. However, it’s the next section which helps propel this set from a gorgeous paperweight into one of the best TOTL flagship iems that my ears have heard.

That sound! ​

Beyond the aesthetic, build quality, packaging/Accessories, what makes the Omnium one of the better sets within its price point is…THAT SOUND! I’m sure that’s what you all came for anyways. The Omnium has a very nice balance across the spectrum, warm/neutral, very cleanly defined, awesome mix of smooth and crisp, with a stage which sounds wide, deep, and holographic. Timbre is very nice as well. I don’t hear anything outright peaky, glaring, or too sharp. Everything is kept in great control. Nothing metallic, no sibilance and cohesion of drivers is really special. The Omnium has this deep and vibratory sub-bass that reaches guttural levels serving as the foundation of this set striking a bold contrast against the levity of the upper portions of the mix. The mids are both technically on-point as well as emotionally gratifying. Forward, great clarity, tight transients, lean yet dense. Nice musicality and great technically! The treble is easy going, never strident or too vivacious, yet the Omnium’s treble is not without nicely controlled vibrance. Also, the extension into the upper treble sounds well tuned, nothing splashy, no treble tizz. Again, the stage is well dimensioned, intimate yet full, 3D in its rendering as the stage really adds to the whole experience. Nice with details, solid separation of elements of the stage, well layered, Imaging is spot-on too. Now, there are some subjective gripes that some may have but in my opinion the Omnium is a very nice all-rounder flagship iem that’s worth every penny to own. If you can do it. Obviously for those who cannot afford such a set there are many iems within the market which can almost get you there and cost much less. For whom it’s for… yes, the Omnium is worth the asking price.

Conclusion​

To conclude my full written review and feature of the Craft Ears Omnium I again have to thank the good people of Craft Ears for supplying the Audio Geeks USA Tour with a set of the Omnium in exchange for a full review. With that, I also want to thank Audio Geeks as I wouldn’t have been able to dive into a set like this without them. I thank both outfits very much! Also, I need to thank you, the reader, for clicking the link and spending time at Mobileaudiophile.com. Every time you click a link to this website it is very important to us. Without question we are trying to build our reach and that doesn’t happen without you. Granted, we’ve really grown in a special way with many many followers, and we couldn’t do any of it without you. Thank you so very much.

Other Perspectives ​

Now that you’ve read my full review and heard all of my thoughts and my perspective of the Craft Ears Omnium, I am urging you to go and check out other thoughts of this wonderful iem. At this price I’m sure I don’t have to tell you this, but I’m urging you nonetheless. Every reviewer has the potential to be very different from the next. Just like you. We all have our own tastes in music, we all have different preferred sound signatures, likes and dislikes. Beyond those things, we don’t all have the same gear, which can greatly change how we perceive each product we review. Also, not all of us have been down the same road in audio. We’ve had different experiences in the hobby. There’s a thousand variables which differ from the final thoughts and opinions we have. So, it really does pay for you to do your due diligence and read, watch, or listen to all of the opinions. Well my friends, I am all out of words, I hope each and every one of you are healthy and happy. Take good care, stay as safe as possible, and always… God Bless!

Craft ears omnium



Is a great that sound natural clean refined that’s very dynamic micro-detailed through its mids and vocals.





View attachment IMG_2710.jpeg



Bass:

The bass is nice textured also well controlled, midbass in particular is very polite and it never bleeds into the mids so the omnium stays clean through its mids which makes the vocals shine, and pop out more than usual, tho I wanted more mid-bass slam as bass head I think the Omnium lacks mid-bass overall in result it makes the iem not the ideal choice for bass dominated genres like hip-hop, EDM, and Reagaton. Sub-bass is nice and textured and very high quality comparing to other TOTL iems.

Treble:

Treble is very well-extended and shines depending on the sources but overall it’s very smooth and revealing without being fatiguing, also, it helps the Omnium to sound holographic and wide through its stage. I think the mostly correct sounding iem. Although it uses BAs for its treble, the high frequencies arevery nice bit more relaxed in the lower treble which keeps the Omnium non-harsh iem, and it will give the right amount of treble emphasis. Some may wish the treble had more energy at least through the lower treble to give a bit more energy for the details that sit in the back ground that represents the harmonics that are carried in the upper mids/lower-treble which usually keep the experience more enjoyable but maybe fatiguing that’s why the Omnium takes a different approach and it follows more of relaxed treble that’s clear and revealing and none-fatiguing instead.

Mids:



The mids are the star of the show in this iem where the micro details and vocals are emphasized but it’s a very unique tuning that I have never experienced before with other iems. The Omnium is able to pull a lot of information through its mids. You are able to hear the separation in the vocals, also you will be able hear a clear breaths that’s it’s very emotional so vocal lovers will definitely enjoy this type of presentation. Instrument placing is top tier well imaged, and separated by the Omnium.


Overall:

The tuning of the Omnium will shine with pop, accustics, and anything that doesn’t require a lot of warmth and bass slam. The Omnium is a top tier iem that has a very natural sound signature that feels like reference that could suit audiophiles that like correct sounding monitors that won’t over color any part of the frequencies.





Comparisons:



Vs RN6

The Radon is a whole lot more warm iem and it does slam much much harder than the Omniim also it has stronger treble emphasis and extension thanks to the single EST driver for the high frequency; the Omnium is more neutral and it feels more reference tuning compared to the RN6 also Omnium seems a very relexed version of RN6.



Vs XE6



XE6 is a very warm iem even more than the RN6. XE6 has crazy mid-bass slam, also has a very well extended treble that’s very energetic and resolving. XE6 is more engaging compared to RN6, and the Omnium, but the XE6 will be more close in tuning to RN6 than the Omnium as both are very warm iems, tho RN6 is more natural than XE6 and the Omnium is a lot more natural than RN6. Fir-audio monitors offer very warm listening experience that’s supported by huge amount of bass, and well extended treble that’s very resolving, and engaging more than the Omnium’s treble. If you are a treble-head then XE6/RN6 will be better option than the Omnium also, if you are a bass-head RN6/XE6 will also be better options than the omnium as they have that bass impact that you can really feel through the outer driver(Kinetic bass). Overall, depending on your preference, and what you like in an iem all three iems have TOTL performance but they differ in their presentation.

XE6: will offer huge mid-bass and very well extended treble that’s none-fatiguing and less detailed than the other two monitors.



RN6: will offer natural midrange that will allow the vocals to shine and have some note weight in fact the upper mid range/lower has amazing energy that will be more engaging than the Omnium but it could be fatiguing to some the treble has certain peaks in the CIEM version, where as the XE6 and Omnium treble is more smooth or none-fatiguing as the RN6. However, both RN6/XE6 will offer thicker sound whereas the Omnium is a whole lot linear sounding.



Omnium: has less upper midrange to lower treble energy, which makes the prostration less fatiguing and more relaxed comparing to RN6/XE6. Instead, the Omnium will have a less bass, and treble than RN6/XE6 and its whole presentation is focused in its mids which lets the vocals shine and easier to hear the separation and breaths than the RN6/XE6 but due to RN6 tuning of the upper-mids/lower treble the background harmonics will sound more engaging and more detailed than the Omnium. Overall RN6/XE6 will have thicker sound than the Omnium whereas the Omnium will sound linear reference like but due to its unique tuning it will be very engaging and dynamic yet natural and none-fatiguing.



Vs Mest mk2

Mest mk2 is one of my favorite iem that’s exciting and dynamic that has a very spicy treble performance, tho it carries that warm-bright tonality it’s very close to the Omnium’s in tuning which a reference like tuning except the Mest will have more treble emphasis Omnuim will have better technicalities, The Omnium has wider-stage and better imaging than the Mest while the Mest will be more enjoyable for those who love treble a lot. Both of these iems try to follow that bright-warm style but both iems are more bright than warm. Overall, the Omnium offers the better listening experience than the Mest mk2 and it’s a step above in terms of musicality, right timbre, instrument placement and separation.

Sources:



Hiby: R8ii and R6P2



Both make the Omnium sound dynamic and natural without over-coloring any part in fact the iem does stay natural across many sources but I think it will shine more with warm sources instead of the natural and organic feel of Hiby daps. Although with the Hiby devices the presentation of the Omnium is very engaging, exciting, holographic, I do get better listening experience with the R8ii than the R6P2; the separation and the imaging are rendered better on the R8ii than the R6P2.





Questyle M15:

Sounded really good with the Omnium, there is a sense of more slam using the M15 with the Omnium a. Overall the M15 is a very great paring that makes the Omnium fun engaging but maybe also intimate in the soundstage, are Vocals are more forward comparing to the R8ii/R6P2, But definitely a better source for the Omnium will make listening experience better as the Omnium scales up with better sources.




Here is my video review below:

Summary


Craft Ears is renowned for their high-quality, handcrafted in-ear monitors designed for both musicians and audiophiles. The Omnium features a unique and advanced driver setup, ensuring a full-range and balanced sound signature. It includes a single 9.2mm LSR dynamic driver dedicated to producing deep and impactful bass, a 10mm planar driver for articulate and natural mids, one balanced armature for high-mids, two balanced armatures for highs, and two more for super-highs. This configuration ensures every detail in your music is captured and reproduced precisely. The Craft Ears Omnium is an ambitious launch into the IEM market, offering a sound that balances accuracy, musicality, and technical performance. It boasts premium build, detailed tuning, and excellent performance with my current sources, the Cayin RU7 and Earmen Angel.


This review reflects my personal and subjective listening experience with the mentioned audio gear product. I would like to thank Craft Ears and Audio Geek Brotherhood of Audiophiles for organizing this review tour in my country and allowing me to share my thoughts on the product. This review is not influenced in any form and I have not been compensated.

Before I start, I would like to mention that most of my impressions of the gear are based on the sources and test tracks mentioned, so your mileage may vary.

Build & Design

The Craft Ears Omnium exudes craftsmanship, as is evident with most IEMs in this price range, especially from manufacturers who take the aesthetics of their IEMs seriously. The shells are sleek and ergonomic, offering a snug and comfortable fit for extended listening sessions. The finish feels premium, with intricate detailing on the faceplate, hinting at the precision put into both aesthetics and function. Despite being slightly larger than average IEMs, the Omnium rests securely without causing fatigue.

The included cable is of good quality: supple, durable, and free from microphonics. However, it leans towards a dry sound. I was happy to receive the Penon GPS from the Audio Geek group to enhance my experience with this IEM. The Penon GPS is sturdy, complementing the Omnium’s sound signature and bringing more life to its sound. The connectors on the Penon GPS fit perfectly.


Sound Quality

The Craft Ears Omnium stands out for its balanced yet engaging sound signature. It is neither clinical nor overly warm; instead, it walks a fine line between technicality and musicality. This makes it suitable for critical listening while maintaining a layer of fun that prevents fatigue.

Bass

The bass presentation is clean, controlled, and layered. Sub-bass has excellent extension, delivering a natural rumble without bleeding into the midrange. Mid-bass is tight and punchy, with fast transients that lend energy to genres like EDM, rock, and hip-hop.

When paired with the Earmen Angel, the bass becomes particularly impactful. The Angel’s clean amplification allows the Omnium to dig deep into its low-end response, adding a tactile weight without bloating.

The Cayin RU7 offers a more analog and natural presentation. The RU7’s warmth in NOS (non-oversampling) mode enhances the Omnium’s bass body.

Midrange

The mids are where the Omnium shines brightest. Vocals, both male and female, are presented with a sense of intimacy and clarity. Instruments like pianos, strings, and guitars are articulate and natural, with excellent note weight and decay.

The Earmen Angel enhances microdetails in the midrange, creating a slightly more forward vocal presentation that suits vocal-centric tracks. The Angel’s dynamic punch also lends energy to live recordings, where instruments benefit from added separation and layering.

Meanwhile, the Cayin RU7 offers a smoother, more organic midrange presentation. Vocals sound lush, with a slight warmth that enhances emotional delivery.

Treble

Treble on the Omnium is detailed, extended, and free of harshness. The tuning avoids excessive brightness, keeping the IEM fatigue-free even during long listening sessions. Sparkle and airiness are present, allowing cymbals and high strings to shine without overshadowing the mix.

The Earmen Angel brings out treble energy with exceptional control, while the Cayin RU7 provides a smoother, slightly rolled-off treble.

Technical Performance

Soundstage & Imaging: The Omnium boasts an impressive soundstage for an IEM. It presents a wide, airy sense of space with excellent separation and imaging. Instruments and vocals are precisely placed in a three-dimensional space, making orchestral and live recordings particularly immersive. The Earmen Angel excels at expanding the soundstage width, while the Cayin RU7 adds a more holographic depth.

Detail Retrieval: The Omnium’s detail retrieval is top-tier. Microdetails like subtle breaths in vocals or the resonance of guitar strings are rendered effortlessly. The Angel enhances this with sharper dynamics, whereas the RU7 provides a more natural, organic presentation of details.

Dynamics: Dynamics on the Omnium are punchy and lively, particularly with the Earmen Angel, which excels at delivering tight, impactful transients. The Cayin RU7, while slightly softer, brings a fluidity to the dynamics, lending an analog charm to crescendos and drops.


Synergy with Sources

Earmen Angel

The Angel amplifies the Omnium’s strengths: clean bass, forward mids, and sharp treble energy. It brings a sense of dynamism and precision to the IEM, enhancing both macro and microdynamics. This pairing is ideal for critical listeners who crave detail and punchy, engaging sound.

Cayin RU7

The RU7 adds a natural, musical touch to the Omnium. The NOS mode particularly complements the IEM’s tuning, softening any sharp edges and lending a fluid, analog-like warmth. This pairing is ideal for listeners who value timbre, emotional delivery, and a relaxed presentation.

Final Verdict

The Craft Ears Omnium is a masterfully tuned IEM that delivers balanced, detailed, and engaging sound. Its performance scales exceptionally well with a variety of sources, offering both musicality and technical brilliance.

Thanks to Jedrzej (“Jed”) Nowicki, CEO of Craft Ears, and the Audio Geek USA Tour, I have had the extremely fun opportunity to demo the Polish-born, Craft Ears Omnium, the brand’s flagship IEM which retails at €2499 (appx $2700USD). I want to thank Jed profusely for providing this unique, addicting IEM for tour in the USA and for supporting our tours in general! I will be excited to hear what other members have to say about this one, for sure. I will say upfront that, for me, this unique TOTL IEM took me slowly and by surprise!

Omnium is a 7-driver tribrid IEM with 1x DD for the lows, 1x planar (!) for mids, and 5x BAs handling all the rest. I am always intrigued with the inclusion of planar drivers in multi-hybrid IEMs, owning one myself, the Custom Art Fibae 5, also from Poland! Interestingly, the planar is not used for highs as I would expect, but for lows/mids to complement the DD. Also like Fibae 5, Omnium uses a flat impedance technology so that Omnium remains similar across devices. Omnium is placed firmly in the high-end of the hobby, retailing at about $2700USD depending on exchange rates as it’s actually sold in euros at €2499. As an American audiophile, you need to order Omnium directly from Craft Ears (https://craftears.com/products/craft-ears-omnium-universals/), though I imagine at some point in the not distant future, you should be able to get them from one of the big US distributors. But dealing with Craft Ears is a pleasure and they are able to serve the world from their little corner of Poland. In fact, a fellow head-fier figured this out, bought Omnium, loved it so much, he traded it in for a custom that he continues to use to this day. I have also read further that their customs are fantastic, so nice to know it’s available and solid quality.

The Omnium’s nice and thankfully small package gave a complete, but spartan, unboxing experience, including a Pelican-like hard plastic case for carrying the IEM, its 4w SPC stock cable (that I did not roll, nor did I feel the need to) and eartips (which I did not use or test as this is a tour unit). The beautifully and solidly crafted shell is on the medium/large side and had a tricky fit for me at first; it took me awhile to figure out how to best seat these monitors for maximum results. The key for me was to get a very deep and snug insertion in the ear canal because, without that, they sounded off. With that accomplished through the help of Divinus Velvet wide bore tips, the Omnium roared alive with its unique sound signature. I also gave Omnium a full 100-hour burn-in, though I think by 50 hours, it had settled nicely, though burn-in definitely helped.

First, the build quality and sheer beauty of the Omnium shells is exactly what you want in an expensive, TOTL IEM. It exudes class with its crystal covered carbon-fiber background surrounded by 18k gold plating. The included stock cable is a substantial, but very ergonomic 4w that looks and sounds the part, and I really felt no need to change it out. This package is really a treat for the eyes! How about for the ears?

Omnium has a unique tuning for me. The uniqueness is hard to describe, but I don’t think I’ve heard IEMs that sound quite like these before. There is a very wide open sound here that is almost bafflingly well separated and presented across the FR that has an understated, but beautiful, bass. If anything, they most remind me of Elysian Annihilator 2023 in the treble (not in the bass), but also strangely sound like a Sennheiser HD800s headphone in overall presentation, except that the sound is more immediate and less dispersed being an IEM. But if someone asked me for an IEM with a resemblance to HD800s, this would be the first one to come to mind, as the staging and sound presentation are similar to me. It’s the most open-sounding, closed IEM I think I’ve heard (still need to try Melodic Artification Alter Ego, an open back IEM).

So, Omnium is not so typical or easy for me to categorize, and I have been listening to a lot of IEMs for awhile now. I would say the tuning is a neutral U-shape with forward mids. It’s a fairly balanced tuning, and I would say outright, this is not a basshead set, though its bass is very well tailored and has good deep rumble when called for. But bass will not be the big sell for Omnium as its quantity is decidedly on the lighter side; again imagining that a custom set might generate a wee bit more bass feel). There sounds to me like a scoop in the midbass which causes the mids and treble to achieve some of the airiest and widest sound I’ve heard in an IEM, a lot like I hear from the HD800s. The midbass is handled by the planar driver and is very genteel and also on the lighter side, though it’s certainly there and doing its thing to keep this ship afloat. This can create a thin sound with bad recordings, but with good ones, it’s quite revealing and enjoyable, and for some reason, even without all that bass, everything sounds just right.

So what’s the surprise? Upon beginning my listening with Omnium, I was immediately aware that it sounded very different from any other IEM I had yet tried. Also, that its tuning would not typically be the sound signature for me – it can be a little bright for me and a little bass light (for lack of a better description) – but for some reason (likely brain burn in), this didn’t turn me off. And I couldn’t put it down during my time with it, having many multi-hour listening sessions and enjoying what is normally not my cup of tea. I would sometimes do a little back and forth with my new Macbeth and Rival alongside the Omnium, and they are dramatically different, making Omnium a potentially great complement to those more bass-rounded sets.

I’ve heard other balanced, bass-light tunings, and not-a-one has been able to captivate my attention like Omnium. And the more I listened, the more this tuning grew on me. So, ultimately, I was very pleasantly surprised by the uniquity of the Omnium and I could see adding it to my collection for that – a presentation that I do not have with any other IEM in my horde and one which I learned that I apparently like! It’s not going to take away my preference for heavier bass sets with denser sound, but as a counterpoint to them, it’s extremely seductive and fun. It sounded great across all of my sources and I had many multi-hour sessions without fatigue or discomfort. Truly a beautiful creation! Bravo, Jed, you are a talented man!!

CRAFT EARS- OMNIUM REVIEW

DISCLAIMER: The Craft Ears Six was purchased directly from Craft Ears with a small discount. We At Aural Cafe would like to thank the Craft Ears team for this opportunity and their support for Aural Cafe.

Introduction: -

Today at Aural Cafe we will be reviewing Craft Ears Omnium which is Craft Ears' latest flagship offering. Craft Ears Omnium is a hybrid IEM featuring a 7-driver setup in a 6-way crossover along with Craft Ears' proprietary patented technologies. It comes in both Universal and Custom versions and we will be reviewing the universal version.

Craft Ears is a Poznan, Poland-based company founded by Jedrzej Nowicki in 2019. Jedrzej Nowicki himself being a drummer, music producer and audiophile pivoted his lifelong passion for music into Craft Ears intending to not just create ‘another IEM’ but to come up with something unique that can offer unparalleled musical experience. The mission was to not just sell Hi-Fi in-ear- monitors but to enhance the musical journey for audiophiles and musicians alike, offering a gateway to experiencing music in its purest form. Being in this hobby for the last 9 years we at Aural Cafe were closely following Craft Ears launches regularly and wanted to own and test their IEMs. We have recently reviewed the glorious Craft Ears Six in Aural Cafe, and one can go through the review by clicking on the following link (https://www.facebook.com/teamauralc...Lfxsa5vhwTjkyDcpCrsS4zMFMTs4Zbo5ewuwofAzoTGAl). We were truly impressed by Craft Ears Six which increased our excitement to review Craft Ears' latest flagship offering ‘OMNIUM’. So here we are again with another review, this time for the mighty Craft Ears Omnium.

Craft Ears Omnium is the latest flagship offering from Craft Ears designed for both professional musicians and tasteful audiophiles. The aim of the Craft Ears team through Omnium is to achieve the pinnacle of audio engineering while offering exceptional sound quality and craftsmanship. Craft Ears Omnium features an advanced tubeless design setup along with custom-tuned acoustic chambers and resonators. Craft Ears Omnium, being a hybrid flagship offering utilizes Dynamic Driver (DD), Planar Magnetic and Balanced Armature (BA) driver in a unique and advanced seven-driver setup to ‘Redefine’ the art of listening. A single 9.2mm Liquid Silicone Rubber (LSR) dynamic driver is implemented to churn out deep and impactful bass, while a 10mm planar driver is utilized to extract articulate and natural Mids. Upper Mids are handled by one carefully selected BA along with two additional Balanced Armatures for the highs and another two for ultra-highs. The unique and advanced driver setup aims to come up with a full-range and balanced sound signature where every detail in the soundtrack is seized and reproduced with high precision. The seven drivers are implemented in a 6-way crossover along with Craft Ears proprietary technologies which are as follows:

• Tubeless Design setup is implemented in Omnium for the first time by the Craft Ears engineers along with custom-tuned acoustic chambers and resonators with the help of 3D printed Shell incorporating unique waveguides to achieve realistic low-end notes and HiFi sound delivery.
• True Load™ technology is implemented to deliver extremely flat impedance and phase, ensuring increased cohesiveness and consistent performance across different HiFi sources irrespective of its output impedance.
• SES 3.0 ™ (Space Expanse System) is the third generation of Craft Ears' very own field-specific, 3D printed, horn-loaded tweeter system implemented to achieve wide soundstage, excellent extension in high frequency along life-like texture.

All in all, we at Aural Cafe feel that the Craft Ears team through the implementation of the above-mentioned tech in Omnium have tried to again push the boundaries of sound excellence to achieve an exceptional sound signature. It comes in both Universal and Custom versions, and we will be reviewing the universal version which now retails for 2499 €.

Unboxing Experience, Design & Build: -

As you can see from our unboxing video () the Craft Ears Omnium arrived in a simple Dark Grey coloured cardboard box with Craft Ears Logo embossed in the Jet Black colour on the front. On opening the box, one is greeted with two Craft Ears Stickers and one printed note welcoming us to the Craft Ears family. After which we are welcomed with a Solid high-quality all-proof Pelican-style protective carry case being placed on the black bubble sheet in the box. The black Pelican-style protective case is of high quality if we compare it to the Pelican-style protective case we received from other brands. The Craft Ears logo along with the brand name is embossed right on the top of the Pelican box along with the Craft Ears model name which was Omnium in our case. On opening the box, one is pleasantly greeted with IEMs and the high-quality modular copper cable being placed neatly in the custom cutout while the accessories are tucked neatly inside the zippered mesh pocket. The removable zippered mesh pocket is one of the most convenient features of the Omnium carry case which is attached inside the top flap of the case and becomes very handy to organize the accessories neatly. Now moving on to the build quality of the IEMs each pair of Craft Ears Omnium is handcrafted in Poznan, Poland by a team which have more than ten years of experience in crafting IEMs. Craft Ears Omnium is manufactured using premium 3D printed technology along with proprietary waveguides to optimize sound delivery. The universal version comes in a single-tone jet black colour featuring a real carbon fiber faceplate with Craft Ears Logo embossed on the faceplate in golden colour. The tale doesn’t end here as the Omnium over-edge faceplates are shielded with 18k gold plating screaming opulence and elegance from every corner. The mix of black and gold colours along with the real carbon fiber faceplate looks very fun, unique and aesthetically pleasant to the eyes. The primary shell is manufactured using top-quality resin which adds to the overall elegant and premium look of Omnium IEMs. The nozzles are of standard size incorporating a Three-bore design and are uniquely angled which ends up providing custom type fit and isolation. When it comes to stock cable Craft Ears Omnium comes with high-quality 1.5-meter modular 2-pin copper cable with a clear PVC jacket. Omnium being the flagship offering from the house of Craft ears the added modular cable does help a lot to swap across different sources. When it comes to accessories the Omnium comes with minimal but useful accessories. The 3.5mm connector of the stock cable and the transparent ear tips box end up becoming part of Omnium accessories. Both the long-lasting and 4.4 mm and 3.5 mm connectors feel solid with high quality. When it comes to ear tips the Omnium ear tips box comprises two types of silicone ear tips. one set of translucent narrow-bore single flange ear tips in S, M, and L sizes and another set of black wide-bore dual flange ear tips again in S, M, and L size. The stock ear tips are of good quality with narrow bore single flange ear tips primarily catering to lovers of low frequency while the wide bore double flange ear tips feel like catering to the lovers of mids and high frequencies. When it comes to sealing the dual flange, tips gave us better seal and isolation over the single flange ear tips. We at Aural Cafe just adored the elegant yet premium look of the Omnium carbon fiber faceplate and loved the high-quality 3D-printed Omnium IEM shells. The modular copper cable along with solid connectors feels like of very high-quality core and the two sets of ear tips will surely help the Omnium buyer to choose the right one as per his or her ear shape for the best seal and isolation. All in all, we can say the unboxing experience of Craft Ears Omnium is simple, professional and minimalistic with a total focus on sound and quality of IEMs, cable and other accessories.

When it comes to fitting, the Omnium’s shell is a bit bigger than the standard IEM’s shell. As far as we are concerned, we didn’t have any problems with the overall fit and comfort of the Omnium. The weight of the IEM shell is just right for long listening hours. The smoothened 18k plated edges also add to the overall comfort while listening to music. The design and the built-up quality of Omnium IEMs feel very premium and solid. So, one thing is sure the Craft Ears team has given supreme importance to the longevity of their flagship IEMs. The Omnium, although being universal IEMs provides a custom type fit and high passive isolation which becomes very handy while listening to music in noisy places. We are quite impressed by the Omnium’s design and fit especially with the uniquely angled nozzle which provides excellent passive isolation

• Tonality: - After listening to various genres of soundtracks for weeks and months now, using different kinds of portable and desktop rigs with Craft Ears Omnium, we at Aural Cafe feel that Craft Ears Omnium exhibits neutral tonality with an iota of warmness. Each part of the frequency, the lows, mids and highs are tuned in a precise and balanced manner without leaning more towards any specific slice of the frequency range. The Craft Ears team have done a commendable job in the implementation of three different types of driver tech inside the Omnium. The sound tonality is smooth and balanced across the frequencies with top-notch cohesiveness between the three different driver technologies making us feel as if we are listening to a single dynamic driver-based IEM. The 6-way crossover is implemented very precisely to get the best out of the LSR Dynamic Driver, Planar and Balanced Armatures for which they are held in high regard. After trying out several aftermarket premium cables with Omnium we realized that the stock copper cable also plays an important part in the overall tonality of the Omnium by adding a decent amount of warmness to the overall sound tonality. The timbre of the musical instruments is very natural and organic along with lots of transparency across the frequency which puts the Omnium in head-to-head with other flagships IEMs available in the market. The sound field especially is quite large which makes Omnium unique in comparison to other IEMs which we had the honour to test and review at Aural Café. The cosmic sound field makes us feel as if we are attending a live concert. The neutral, balanced and smooth tonality not only makes Omnium go with most genres of soundtracks but also helps during long listening hours without any kind of fatigue. When it comes to Aural Café, we just loved listening to ‘Stairway to Heaven’ by Led Zeppelin and ‘Mera Jahan’ from the movie Tareen Zameen Par composed by Shankar-Ehsaan-Loy.

• Lows: - The lows on Craft Ears Omnium are tastefully tuned with the help of a very capable 9.2mm LSR dynamic driver (LSR) which has been previously spotted in premium items such as Elysian Acoustics Pilgrim Noir and Vision ears EXT. LSR dynamic rubber is a dynamic driver where the diaphragm is surrounded by the Liquid Silicone Rubber thus acting as its suspension. The LSR Dynamic Driver helps in achieving deep natural lows along with low harmonic distortion. The story doesn’t end here as Craft Ears has adopted a tubeless design setup for the first time in their lineup of IEMs. The tubeless design setup helps the engineers to work with a lot more airflow and helps in achieving deep natural lows. The Lows on Omnium is tuned in a very precise manner keeping its neutral tonality in mind which holds onto its region without bleeding into mids, shining brightly along with amazing speed and slam without ever coming on face. The team at Craft Ears focused more on the quality over the quantity while tuning the Lows. The mid-bass is very tight and clean along with top-notch dynamics and speed while the sub-bass is presented in a more subtle way where it is never overpowering the whole bass region. Some bass heads might find it lacking in sub-bass. Here we would like to add that the 9.2 mm LSR DD in Omnium loves high-quality clean sources, and the lows go very deep with quality sources such as Dethonray listening M1 in our case. The mid-bass on Omnium especially becomes very agile with Dethonray Listening M1. When it comes to transient response the overall transient response is precise and top-notch. The mid-bass will give you an extremely enjoyable experience while listening to tracks like ‘Swashers’ by Yoshi Horikawa and ‘Chunky’ by Bruno Mars. For tracks like ‘Nakshatram’ by Jean Du Voyage we expected to have a tad bit more sub-bass emphasis. However, Omnium ultimately provides a satisfying mid-bass focused frequency response that is perfectly clean and finishes off the complex soundtracks with ease.

• Mids: - The mids of the Craft Ears Omnium are taken care of by the 10mm Planar Driver and a custom-tuned Balanced Armature driver as a whole and it is where the magic happens. Planar drivers are generally known and respected for their speed, dynamics and top-notch transparency. The tuning and technical ability of the planar driver surely contribute to this impression. When it comes to positioning the mids on the Omnium is a tinge more forward and immerses smoothly with the lows and high frequency. Also, when it comes to the effect of the drivers on the mids we felt that the Balanced Armature driver makes the upper mids absolutely exciting but it’s the planar driver that takes the lead as it adds the soul and a sublime texture to the vocals in the mids along with a smoother upper mids suitable for long listening hours. Both the Male and Female vocals are absolutely outstanding. Tonally, the Omnium showcases excellent transparency, yet it isn’t perfectly neutral as we have already stated about the positioning of the vocals. The top-class resolving power along with clean tuning made the magic possible to deliver an effortlessly delicate, spacious, and complex midrange. While listening to ‘Laal-Ishq’ from the movie Ram-Leela composed by Sanjay Leela Bhansali and voiced by Arijit Singh, the male vocals felt so soulful that it could drive you floating in the musical abyss. Both the male and female vocals sound clean with lots of soul in them but it’s the female vocals that take the lead over male vocals in Omnium in terms of texture. Micro details are retrieved by Omnium in a very smooth and effortless manner. What makes Omnium special over other IEMs in this frequency range is its capability to take you right to the middle of a live concert where every layer of the soundtrack is present smoothly and effortlessly. While listening to “Zariya” composed by A.R. Rahman for Coke Studio India the vocals of the lead vocalist and Chorus had accurate layering and positioning which was so fun and immersive to experience.

• Highs: - The Craft Ears Omnium is tuned with the help of two custom-tuned Balanced Armatures for highs along with two custom-tuned Balanced Armatures for ultra highs. We at Aural Café can confirm the team at Craft Ears was able to achieve a very linear treble response to the highest frequencies for the Omnium. The whole treble region is very refined and resolved. The upper treble is very much extended and airy without being too harsh injects headroom and micro detail into the sound without affecting the overall tonality and exactly what we can expect from a TOTL set. The Omnium is even-handed in its presentation, delivering almost everything in equal proportion. The upper treble showcases class-leading details on the Omnium while listening to rock soundtracks such as ‘Whole Lotta Love’ by Led Zepplin and Western Classical Music as a whole. Also, the notable mention is it handles complex tracks like ‘Santo Domingo’ effortlessly demonstrating its technical capabilities and we never found any congestion anywhere.

• Soundstage & Imaging: - The Omnium is truly a TOTL set from Craft Ears that has an excellent separation with a huge and spacious soundstage. The soundstage is so wide that some might find it distracting a bit. But for us, we have enjoyed a lot the width with which the class-leading imaging comes. These two features truly complement each other. The Craft Ears Team seems to have worked hard to keep the holographic soundstage uniquely immersive. We enjoyed tracks like ‘Thriller’ from the king of Pop, Michael Jackson like never before with its pinpoint accurate imaging. Using the wide soundstage, this song itself became a unique experience. While listening to ‘Money or Nothing’ from Dire Straits the outstanding separation further showcases the level of space and augments the effect of openness. Here we would also like to add that the soundstage depth increases a lot when used with quality sources such as Dethonray DTR1+ Limited Edition in our case.

• Synergy:- We here would like to state that we at Aural Cafe give absolute priority to source-matching. Being highly impressed by Craft Ears’ Omnium we tried it with numerous sources, cables and tips to see how it affects the sound quality. We also recommend burning the Dynamic Driver and the planar for at least 20 hours to open the overall sound field on Omnium to the most.
  • We have tried Omnium with various sources such as Dethonray DTR1, DTR1+ LE, Pegasus SG1 Gold, Astell & Kern SP1000m, and Aune M1p and with semi-portable desktop sources such as Dethonray Listening M1 and Shanling H7 also tried with a number of dongles such as Aune Yuki, Tanchjim Space and iFi Go Bar Kensei. We can confirm that it matches the best with Pegasus SG1 Gold, Dethonray Listening M1 and iFi Go Bar Kensei. The warm sources like SG1 Gold further improve the sub-bass presence and overall bass presentation along with the improvement in Male Vocals. We also observed the capacity of power handling in Omnium. The dynamics improved significantly with powerful sources like Dethonray Listening M1.
  • For the cables, it matches with pure Copper Cables like PW Audio Monile Shielding and Rhapsodio Copper Wizard. Both add a tinge of warmth to the overall frequencies. However, the stock cable is already a capable one we do not recommend pairing the Omnium with a generic pure silver cable We especially like to add here that we just loved its pairing with Linksmith's ‘Fire Rock Poison’ cable. The mid-bass hits a bit harder on Omnium with the cable along with a tad more rumble on the sub-bass region.
  • We have already declared that among the given stock tips we preferred the narrow-bore silicon stock tips. Apart from that, we loved it with Spinfit CP145 ear tips as it improved the bass. Also, the Divinus Velvet ear tips which add a tad bit of excitement in the mid-range for the Omnium increased the enjoyment of vocals-heavy tracks.
  • When it comes to drivability Omnium can be driven with a HiFi dongle but to experience the Omnium as its best we at Aural Cafe would definitely suggest matching Omnium with a solid clean powerful source to experience the Omnium at its very best. Since the Omnium has an output impedance of 12 ohms it dazzles at its best with powerful clean sources. In our case, at the Aural Cafe, Omnium matched its best with sources such as Dethonray SG1 GOLD and Listening M1.

Conclusion: -

We at Aural Cafe feel that the Craft Ears team through the Omnium have showcased their capabilities of making the TOTL IEMs. From the outside, the real carbon fiber faceplate, the build quality, and look and feel is super-premium, on the inside it’s the implementation of proprietary technologies and crossover is where the magic begins. We also loved the minimalistic approach of Team Craft Ears when it comes to packaging and selection of carry cases and accessories. The raw technical performance, the emotions of the midrange, and the ability to pull you into the music will be very hard to match, making the Omnium a benchmark. The Omnium is one IEM that will take you right in the middle of the live concert which is an experience in itself. We also loved its pairing with TOTL sources such as Dethonray listening M1 which adds a lot of agility to the lows while the aftermarket Linksmith ‘Fire Rock Poison’ cable ends up adding more mid-bass thump. We would also like to add here that we at Aural Cafe would definitely love a bit more sub-bass rumble in the lows but overall, we would like to conclude this review by saying that if you’re looking for a TOTL IEM which not only looks but sounds premium and elegant then Omnium is an easy choice from us at Aural Cafe.

Detailed Review of Craft Ears Omnium.




Disclaimer:




The Craft Ears Omnium that I received is a part of worldwide Tour initiated by " Audio Geek ".




Introduction:




Craft Ears is a company from Poland that produce Custom and Universal In Ear Monitors, and Omnium is one of their Flagship IEM which retails for 2400 EUR.

It features a Single 9.2 mm LSR Dynamic Driver dedicated to produce deep and impactful Bass. One 10 mm Planar Driver for the Mids. High Mids are handled by One Balanced Armature and another Two Balanced Armatures for the Highs. And lastly Two more BA for the Super High.

It has a 6 way Crossover with an Impedence of 12 ohm.




Build Quality:




The Shell is made of 3D printed body and it mimics a Carbon Fiber pattern,which looks astonishing. The Faceplate are a work of Art which is incorporated with an 18 K Gold plated mirror like finish on the edges. Overall the build quality is Top Notch.




Fit and Comfort:




Omnium has a big and chunky shell. So, there might be a fit and proper sealing issues for somebody which have smaller ears. The biggest issue i face is with the long nozzle with its awkard angle. Luckily for me after trying many attempts, I manage to get my Sweet Spot.




Points to be Noted:




My review is done by using D,s Audio Tripple Shielding UPOCC pure Copper upgrade Cable along with Penon Liqueur Black eartips.




Drivability:




Omnium is very much easy to drive ,even my Hiby FC4 can drive it to its full extent. But by giving a little more power, it shines pretty well. So, I used my XDUOO XD 05 PLUS with MUSES 02 OpAmp to extract all the juices from this IEM. One thing I notice that it pairs well with Warm Sources.




Sound Impressions:




From the Sources i paired with, It has got that typical " W " shaped sound signature. Where Subbass is slightly boosted, Mids are little more forward and even the treble are pretty much extended. But the overall presentation gives a pleasant, energetic, airy and highly resolving impressions.




MIDS:




It has a clean and clear Mids. The vocal and instruments are placed a bit more forward than usual. Note weight aren't thick but its pleasing to listen. What's more interesting is the fact that it hits and slams so hard that I sometimes feel it will blow my head.




BASS:




The Low Frequency region of the Omnium is tight, controlled and beautifully textured. It has got a good quality as well as decent quantity Bass. Both the Subbass and Midbass are present in almost equal quantity. But upon critical listening I found that there is a slight boost in the Subbass region.

When I tried the song " Move On " by Nazareth, I can almost feel the Thunderous rumble of the Subbass and its so addictive and satisfying. Moreover it has got an impressive amount of Midbass which are Fast, Tectile and Snappy too.




Treble:




The treble are well extended as well as energetic. They are clean, crisp and well detailed. On " And Justice For All " by Metallica the Cymbal strikes and High Hats sound phenomenal, even the snare drum hits much harder than usual. Irony is that with all those crisp, clean and energetic high frequency region, it doesn't feel fatiguing nor sibilance occur. It's a finely tuned IEM.




Technical Aspects:




Soundstage:

It has got a wide Soundstage and it's airy too. I feel like I'm sitting in the middle of an Orchestral Hall.

Imaging:

The charm of this IEM lies here. It has got an excellent and precise imaging. There isn't any congestion. The localization and seperation of instruments is so good that it sometimes behaves as having a holographic soundstage in certain tracks.




Resolution:




Detail retrival is quite good. It can even pick those micro nuances. But one thing is sure that Omnium is not a forgiving IEM.




Conclusion:




The Craft Ears Omnium really stand out with its unique Driver Configuration. Looks stunning and above all having a truely Flagship Sound Quality which I enjoy to the fullest.

Disclaimer: - I am a basshead and prefer a wide sound with natural timbre, excellent imaging and thumpy mid bass with moderate decay and clinical precision when it comes to instrument separation. I am highly averse to bright sounding transducers and sibilance in my music.

This unit was sent to me by Audio Geek India as part of the Craft Ears Iem tour. I thank Audio Geek India & Craft Ears for this opportunity to listen and review Craft Ears Aurum. My views aren’t influenced either by Audio Geek/Craft Ears in any way.

I used D’s Audio’s Triple Shielding Silver Cable and Azla Sednafit Light ear tips; for this pairing. Vortex cables Lavinia also complimented it well as it increased the emphasis on the lows but the amphitheater-like soundstage on D’s Audio Triple Shielding Silver Cable was an experience in itself; so that’s my recommendation with this iem.

Source: Ibasso Dx320 with Amp14

Unboxing:

I received a Custom Unit which had a 3.5mm connector, 2 types of ear tips viz. double flange and single flange silicon tips and the iems with silver plated OCC copper cable that is nice to look and hold.

The case is robust and built like a tank. In the retail version you get:

• Iems
• Hardcase
• Custom Made detachable 2-pin cable
• Dehumidifier
• Cleaning tool
• Shirt Clip
• Premium box

Introduction:

Fit: - The fit wasn’t great at first, probably because it is a custom unit made specifically for someone else’s ear, but the seal was proper. These iems are very light and I often checked if they were secure but they never disappointed. Everytime the seal was perfect and after the tip rolling I never felt the need to check.

The moment I played a song on them, the first thing I noticed is the vocals. They simply pop. I would say its too safe a tuning with recessed lows and forward mids but its not your average safe tuned neutralish iems. Infact, despite my preferred taste for forward mid-bass I seem to truly relish any piece of music I threw on it. Its an experience to listen to Omnium that I have seldom felt in any iem.

Lows: Bass Heads beware, you won’t get quantity over here. With little emphasis on mid bass and subdued sub bass omnium still won’t leave you hanging dry. It impresses you with the detail in textures. The presentation is subtle but ensures that you decipher Snare drums, back tom and floor tom individually. I prefer around 6db more mid-bass than neutral but never for a moment, I felt the need to go to my bass head iems as the details kept me engaged. The highly textured lows make you want to try your collection as it gives a very clean and needless to say far from muddy sound, in fact the opposite.

Mids: Mids on the Omnium aren’t heard but can only be felt. Mids so natural and vivid, I felt like I am in the same space where the vocalist was performing. When a vocalist swells and goes like aaaaaaaaaaAAAAAAAAAA on other iems i hear, but on the Omnium due to its dynamics in vocals it sounds like aaAAAaaaAAAAaaAA. The emphasis on each letter gets conveyed and its ability to fool you into believing that it’s a live performance is unmatched. Vocal presentation is forward and also ample air around it. There is a perceivable distance between vocals and other sound cues.

Highs: Even on sibilant tracks this iem protects your ears to any shrill/piercing sound. I couldn’t find one track where Omnium would convey any sibilance or any artefact of that sort. It simply guarantees a smooth yet exceptionally detailed treble. Trebleheads might find the signature to be a bit on the darker side but for most other people I think the presentation is something unique here. You get details in the upper range yet they always remain contained and are presented without any harshness.

Technicalities: Well, I never knew that iems would be able to convey sound cues in such a 3D holographic manner. It feels like the vocalist is standing in the centre of an amphitheatre and like an orchestra different people are playing different instruments. The imaging is precise and when you close your eyes and give it a few minutes it captures you with the details and this holographic immersive effect. The soundstage is wide but it doesn’t flex it all the time. When called upon, you get to hear how distant sound cues can Omnium convey. Effortlessly it just shines in every aspect here and the timbre reeks of flagship. All recordings sound lifelike and airy.

Conclusion: I never expected to write this for Omnium but it’s a ‘Value for Money’ Iem. Yes, I know it’s gonna raise a few eyebrows for sure but that’s my mileage. It has everything that an endgame Iem should have and more. I would go for a custom one if I happen to save enough for this iem. Truly something I cherished reviewing and I would like to thank Audio Geek India and Craft Ears for this wonderful opportunity to listen to this beautiful piece of craftsmanship.

The Polish version of the text from another forum was translated by a translator. Many meanings, mental shortcuts or sense may have lost their value.

The old and new flagships from Craft Ears arrived. Aurum - I listened to them for a very short time, because of their signature, strongly focused headphones. Very close transmission, focused in the middle and not very stretched scene, I didn't like it very much. You could hear the quality, details, but because of this tight transmission, the rest was strongly muffled in my opinion. The universal version didn't sit too well in my ear, which only accelerated the change. I quickly changed to Omnium. After a few courses of pleasure, I started browsing the product gallery on the Craft Eras website - I was lost, it was over. I imagined what my custom-made in-ear monitors would look like. I arranged a meeting at the company's headquarters. The meeting was an hour and a half, I was boiling with emotions and 30 degrees Celsius outside. We talked about music and the project. Jedrula1, explained everything and helped to put the project together from the visual side. The ear impressions were carried out without any discomfort, quickly and efficiently. Thank you to the Craft Ears crew.



I listened to the universal version of Omnium on Azla SednaEarfit Light earbuds.

To describe the general characteristics, I will use the commentary of the late Mr. Bohdan Tomaszewski, a Polish announcer and tennis enthusiast. To paraphrase - "Rafael Nadal is a great player, but he is only a great craftsman. On the other hand, there is only one king - Roger Federer". Both of them cannot be denied results, titles, fighting spirit, talent and writing several pages in the history of tennis. On the other hand, Mr. Bohdan valued Roger Federer more, not without reason. He valued him for the beauty and craftsmanship he presented during his game. Monarch MK3 is such a great craftsman, many like it, it has its undeniable advantages, but Omnium showed what these headphones lack. First of all, this beauty and "musicality". You don't have to boost the extreme bands to show details, dynamics, strength and power of the bass or diamonds at the top. The illusion of a large stage with a lot of space. Craft Eras created headphones that are much more accessible to listen to, they are incredibly musical. They play without any effort, without any boosts in tuning. Lightly. They perfectly transmit music that is easy to digest, with such an amount of detail and dynamics that Monarch was struggling with it before getting used to the Harman curve. For me, this is the biggest advantage like Omnium. Their lightness, combining everything perfectly into a whole in this easy and obvious way for the listener, transmit above-average dynamics and a lot of details from each band. Textures. This is best reflected in the bass. Here, everything has time, resonates, purrs, has time to fade, reverberate, and the next sound, note, does not drown out the previous one. Bass of above-average quality and textures. There is less of it than MK3, but it is much more pleasant and richer. He doesn't have to win with an ace. It's better - the first thunderous serve from the craftsman and the return from the king. Then a beautiful exchange and the audience's applause after playing the point. That's how the bass plays here.



The beauty and musicality of the Omnium is hidden in the middle part of the band. Unfortunately, I lack the skills and ears to describe what is contained there. Beautiful, organic and human, very pleasant, with great dynamics and details. Someone might say that it is colored, but that is not it. It fits perfectly into the whole tuning, a delicate priority is placed on it - this is the coloration. Thanks to this, the bass does not have to be boosted and bang like a high, and the highs do not have to be like rip, come back, rip. All the high registers are clean, just as detailed and dynamic as the rest. Pleasant and beautiful. They reach as high as they should, they are not stretched left and right artificially widening the stage. I will write again easy to listen to.

You can listen to the Omnium louder and it will not tire you out. Nothing in the tuning interferes with listening to the music, someone may miss something or there may be too little of something, but literally nothing interferes. Another sacred thing is that you can't hear the transducers used at all, they are perfectly tuned. Technically great, they reflect what is most important in music and what their technology can do best. Now I will stretch the truth - even in all music genres, and leave the rest for audiophile fetishists.

The only serious glitch is that the Omnium universals make noise with the CMA600i. I have the Effect Audio Cleo II Octa cable from the April Cable Tour - Cleo II Octa at hand and there was noise with it on the Questyle. So it's not the original cable from the set. The second, small, irritation is that I miss this standard stereo space, air, known and replicated for years. Craft Eras has created something different and interesting in this aspect. The planes on this stage are first class with perfectly smooth transitions without exaggerated, clear marking of them in space. Despite this, we can easily indicate what is happening there, where and when. It sounds so natural. There is no clear 3D effect, but there is epic human stereo. It allows you to immerse yourself, focus, enjoy, hear. Below is a quote that best captures this.

Omnium definitely has a much better balance of lows - mids - highs. ...Omnium I had exactly the same impression as @Vaiet wrote above - you listen and everything is simply in its place, each band sounds bloody resolved, on the one hand you can follow every instrument in every band with great precision, and on the other hand it sounds very coherent. For me it's a bit like the kind of playing that a good speaker system gives in an acoustically pampered room, and I'm sitting in the sweet spot.“

Craft Ears opted for a modest presentation and a utilitarian, armoured case. Additionally, a nice touch, named after them. Although I would personally change the layout from Grand Maestro. It has more space for a cable, especially a thicker one. It is better organised and in my opinion easier for everyday use. The included cable, however, stands out a bit from the rest of the set. Supposedly, this is to change in the future.



Customs are heavy (positively), big, compact, a great feeling to hold them in your hand. Adding an eight-core cable, not the one included with the Ciems, there is no dud. The mere presence of such a set heralds considerable emotions and experiences.
Comfort is definitely better. No, they do not disappear in the ear, but there is no fatigue or burning as is sometimes the case with rubber bands. I already know that any next IEMs I buy will be Ciems.

Quickly, the differences to the universal version after the first listening under the influence of emotions:
Bass - even better textures and murmurs.
Highs - more focused, clearer, a bit more smoothed, a final touch.
Midrange - unchanged for now - very good that nothing has changed for now.
Stage - greater depth, a bit less width.

After a few days, the Omnium “custom” has changed very little. They will forgive a lot for poor MP3 quality, but not everything. They gain a lot from very well-made albums and higher quality peaks. They also like current and blanas. Balance helps primarily to stretch the stage a bit, and current ties everything together. The top is even better, but not because of smoothing, which is a bit better, but because of more frost and energy. Additionally, balance draws out even more on the left and right edges.
Sometimes you get the impression, probably depending on the album production, that entire docks are playing and the auricle is active in the process of listening to “moths”. We listen with the whole ear, not the canal. Here, you don’t need a “bone conduction” transducer to achieve a nice effect, a feeling of a small vibration.



The “custom” version turned out to be less sensitive to changing the cabling to my ear. After applying Effect Audio Cleopatra II OCTA, I didn’t hear any major differences. The universal ones reacted more clearly to silver. I heard a bit more detail in the bottom and top, no change in the middle, which pleases me. In short, less magical/analog, more technical/detailed, everything subtle. The bass is more elastic. Strong details, texturing and realism. I am still wondering how much the Omnium made to measure will scale with an even better source/amplifier. I listen mainly on the Questyle CMA600i.

In conclusion, the Omnium is not a short-term WoW effect, it is your best friend.

Craft Ears Omnium Review


Disclaimer

I have been provided with Craft Ears Omnium as part of a review tour held by Audio Geek India. I am not related to Craft Ears in anyway possible and all the impressions I mention here are subjective to my gears used and my listening capabilities.

Introduction

Craft Ears is an IEM manufacturer based out of Poland. All their products are hand crafted with excellent craftsmanship and build quality. They make IEMs in two forms, customs and universals. The IEM, which I have now is their latest flagship, Omnium, retails at 2499 Euro. Omnium utilizes a single 9.2mm LSR dynamic driver for bass, one 10mm planar magnetic driver for mids, high-mids are handled by one BA driver, 2 BA drivers for highs and another 2 BA drivers for super-highs. Omnium also utilizes a tubeless design with custom-tuned acoustic chambers and resonators along with innovative SES 3.0(Space Enhance System) and True Load(Flat Impedance) technology. The earphones are constructed with the 3-D printed body with a beautiful faceplate design in an 18K gold plated mirror like finish in an unique mirror like finish with a carbon-fiber insert. Shells are relatively on larger side, so comfort and fit are totally dependent on one’s ear structure. As far as I am concerned, fit isn’t an issue and was perfect for me. It’s an easier to drive IEM, rated at 12 Ohm, I didn’t find it difficult to drive Omnium with any of my sources.

Coming to sources used for testing: Cayin N7 DAP and Earmen Angel DACAMP.



And upgrade cables used: Triple shielding UPOCC V3 Pure Copper Wire(Grey One) & Triple shielding pure silver(Black One).



Sound Impressions

In short, Omnium impresses with its clean, technical and balanced presentation. Very highly resolving IEM, totally worth its asking price. It does have one or two niggles, but nothing a cable swap can’t do.

Bass has got very good quality and quantity, with very good slam and punch. Has very good rumble, making it enjoyable. Sub bass has good depth. Though I would have wished it went even deeper than it does. But, still, Omnium’s bass is very well made with excellent clarity, quality and enough quantity to make it very enjoyable and musical. It doesn’t bleed into other regions and has faster decay.

Mids sound natural and well placed at center of the stage. Transition from bass to mids is smooth and consistent. Mids section is very clean, well defined and spaced. Mids, both lower and upper mids sound very energetic and have excellent extensions, especially upper mids, where female vocals excel. Note thickness is perfect, neither too thick nor thin.

Treble is very sparkly and detailed. Treble has great extensions and is very energetic. Sound stage has more width compared to depth, which is quite decent. Nonetheless imaging is top notch and very precise. Instruments have very good space between them, where each instrument can be heard with utmost clarity and definition. There’s no congestion whatsoever with any kind of complex songs thrown at it. Cymbal strikes are crisp and clear. No harshness or fatigue found anywhere. Same can be said about its resolution and dynamics, which I found them to be top notch and excellent all through, with perfect reproduction of ups and downs in music played.

All this with stock cable, and now it’s time to see how Omnium reacts to cable changes(cable non-believers can skip) with two third party cables made by D’s Audio from Hong Kong. One is pure copper and other is pure silver.

Triple Shielding Pure Silver Cable From D’s Audio

Immediately, Omnium sounded cleaner overall with more authoritative bass, while keeping its energetic presentation intact. This cable tames treble energy little and bringing refinement over the stock cable. Bass goes deeper than the stock cable, and mids sounding a little thicker. Clearly, a much better cable than the stock cable.

Triple Shielding UPOCC V3 Pure Copper Wire From D’s Audio

Pure copper wire brings down the energetic nature of the Omnium by a notch, making it little warmer and relaxed presentation. It still maintains top notch resolution and technicalities. For those who prefer such kind of presentation, may go ahead with pure copper, but I prefer the pure silver cable over it for its energetic nature, along with authoritative bass performance.

Comparisons

Vs Fir Audio Radon 6:

FIR Audio RN6 is very popular, limited edition TOTL IEM from FIR Audio. I own it for a while and still adore it as much as I did at my first listen. Both RN6 and Omnium has different configurations and RN6 is priced little costlier than Omnium, but can be found at similar or below Omnium’s price point. RN6 has 10mm kinetic DD bass driver, 2 open BA drivers for mids, 1 open BA driver for high mids, 1 open BA driver for highs with sound reflector, 1 EST driver for ultra-highs and with 28 ohm impedance. Both are easy to drive but can scale well with better sources. As far as sound is considered, I find these two sets as complimentary sets. Both are technically on par with each other. RN6’s bass is atypical of kinetic bass driver, has better slam and punch, a speaker like feel that you can actually feel it. RN6’s bass goes much deeper than Omnium, but Omnium has slightly faster decay though. Omnium doesn’t lack bass, but it can’t perform at the same level as RN6. Omnium has better stage width than RN6, which sounds little narrow, but RN6 has better depth. Upper mids/lower treble is more spicier in RN6. Omnium’s mids are neutral, whereas RN6 has thicker mids than Omnium with both maintaining same levels of naturalness and clarity. Performance wise, apart from the ones mentioned above, both RN6 and Omnium trade blows with each other and totally worth to be part of anyone’s collection if they can fund them both. Personally, I will keep them both in my arsenal.

Verdict

Craft Ears Omnium is a very solid IEM, has the perfect chops to compete and stay relevant in today’s TOTL realm. It has excellent technicalities, highly engaging, dynamic and very energetic sound. This is my first Craft Ears IEM to listen to and nothing is better than Omnium to bowl me over. This is a highly recommended flagship IEM for whoever has the moolah to buy it. Absolutely top notch.

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!
