    DISCLAIMER: Custom Art provided me with the FIBAE 4 in return for my honest opinion. I am not personally affiliated with the company in any way, nor do I receive any monetary rewards for a positive evaluation. I’d like to thank Custom Art for their kindness and support. The review is as follows.

    Custom Art is one of the most eminent value-for-money CIEM brands today. Although many have gunned for the throne, a balance between constant invention and community dialog have made Custom Art the most impressive of them all to watch as they grew sonically, technologically, and aesthetically too. Their recent innovations in FIBAE technology and the Pressure Optimising Design have given birth to the FIBAE Black – one of the the best value in-ears I’ve heard period. And now, with top-firing balanced armatures comes the line-up’s fifth entry: The FIBAE 4 – gutsy, bold and a whole lot of fun.

    Build and Accessories


    The FIBAE 4 comes in Custom Art’s signature shoebox, within which are two included cases: A Peli 1010 hard case and a smaller zipper case. Inside the former is the company’s customary Hi booklet, which acts as a quick-start guide, warranty card and certificate of authenticity all in one. There’s also a hand-written date-of-manufacture, which is a nice touch. And finally, below that are your custom IEMs attached to a Plastics One Hi-Res cable, along with a cleaning tool and desiccant.

    FIBAE4-5-14-W.jpg

    It’s become a running gag through my numerous encounters with (Custom Art founder) Piotr Granicki on- and offline to contrast his forward-thinking in-ears with his stubbornly stagnant packaging. This plain, black box has been here since Custom Art’s conception in 2012. At this point in their career, I think a packaging revamp with more prominent branding, a classier aesthetic and a couple more accessories here-and-there is long overdue. At the end of the day, although it’s not ultra-crucial to the success of the in-ears, it would definitely make their already-accessible prices all the more sweet.

    FIBAE4-5-6-W.jpg

    Thankfully, Custom Art have spared absolutely no expense where it counts. The monitors themselves are gorgeously designed, immaculately constructed and superbly fitting too. Although the shells aren’t 3D-printed per se, they do take advantage of Custom Art’s recent shift towards digital processing. The ear impressions are scanned and trimmed in the digital domain. Once the shape is finalised, it’s printed and turned into a cast for the traditional, hand-poured technique. So, you get the precision of digital processing with the transparency and pristine-ness of hand-poured, UV-cured acrylic.

    FIBAE4-5-1-WR.jpg

    Visually, the earpieces are exquisite. The faceplates are a hybrid between maple wood and blue acrylic resin, finished on top with a FIBAE IV logo I quickly put together on Photoshop. Below are clear shells flaunting those top-firing drivers as much as possible. As has always been the case for Custom Art, the in-ears are smoothly finished with zero seams, rough areas or dull spots. The colour-coded wiring for left and right are especially nice touches. Combined with the improved fit thank to Custom Art’s digital processing, my FIBAE 4’s are yet another home run on their fit-and-finish track and record.

    FIBAE Technology

    FIBAE is short for Flat Impedance Balanced Armature Earphone, and it has become Custom Art’s flagship innovation. First introduced with the FIBAE 1 and the FIBAE 2, what the technology ultimately aims to do is preserve the in-ear monitor’s tonal balance no matter the source it’s connected to. So essentially, whether you’re listening to a FIBAE monitor through your laptop or a dedicated DAP, the frequency response should remain the same. This is especially crucial if you plan to use these on mixing consoles, monitor mixers, etc., where the output impedances can vary wildly from one to the other.

    FIBAE2-copy-copy-w.jpg

    However, that doesn’t mean you won’t hear any differences between said laptop and DAP either. Although FIBAE tech leaves the frequency response intact, the earphone will scale based on whatever data is fed to it. A more resolving DAC is capable of exhibiting superior stage expansion, background blackness, etc. So, although these in-ears won’t bridge the gap between capable and less capable sources, it will allow the user to judge those differences in a clearer manner. And, whatever source you choose to use at the end of the day, you’ll always be guaranteed the sound Custom Art intended.

    Presentation

    Custom Art’s FIBAE 4 is a fast-paced, spacey and impactful-sounding earphone. Perhaps Piotr’s most v-shaped entry to date, the in-ear thrives on energy. The low-end provides a bold, gutsy and almost subterranean foundation, undercut by the top-end’s swift, articulate cuts. And, the midrange humbly bridges the gap. However, while monitors of this type usually cause fatigue to set in much quicker than usual, the FIBAE 4 largely avoids this downfall. This is achieved through rapid decay. Images come-and-go with great immediacy, so the listener is never bombarded with noise during listening.

    FIBAE4-5-2-W.jpg

    Now, there is a less desirable aspect to this speed. If you’re one to enjoy lots of wispy, euphonic warmth permeating throughout your soundscapes to bind instruments together, the FIBAE 4 won’t provide that. The images this monitor renders are almost their own little islands scattered throughout the soundscape, rather than one big, unified, wall of sound. Obviously, where this benefits the FIBAE 4 is in separation. Detail retrieval and layering is the FIBAE 4’s strong suit. A clean stable background and precise imaging also make for a tactile and convincing surround sound experience. Again, it’s a refined, smooth, fast-paced sound with bounds of air and space, founded by a dense, bold low-end below.

    Bass

    The low-end is the FIBAE 4’s engine. It’s impact-driven, dense and generously-bodied. There seems to be a rise towards 100Hz that bolsters kick drums forward – one of the FIBAE 4’s highlight instruments. Whether listening to or performing with them, kick drums always cut through the mix very clearly. Personally, I find that feature wonderful when I’m having to learn a new kick pattern from a busily-arranged track. And, it works wonderfully with genres like prog-rock and metal as well, where double pedals are abundant. Past that 100Hz mark though, they low-end dips, especially toward the low-mids. This is what steers the FIBAE 4’s bass towards a quick and open timbre, rather than a warm, euphonic or wet one.

    This dip allows the low-end to have tons of concentrated impact with minimal bleed. The FIBAE 4’s stage remains clean as a result. In fact, clean can also be used to described the low-end notes themselves. Kick drums and bass guitar come through with tons of clarity and textural data. It isn’t this blubbery mess that trades in resolution for volume. Rather, it achieves both through clever tuning and raw extension. I also admire Piotr’s decision to keep sub-bass relatively linear. It’s what gives the bass headroom, and allows the natural textures of the track to come through without any artificial rumble. All in all, it’s a response with the right blend of bigness, clarity and warmth to sit well with a plethora of genres.

    Midrange

    The midrange is where airy and open come in. Instruments are given tons of space – both from each other and from the listener – as they’re positioned neutrally in the stage. One thing the FIBAE 4 never is is in your face; stuffy. Whether or not that’s a good thing will ultimately depend on your tastes. Technically, a low-mid dip encourages definition. Images are well-defined, compact and tight, so there’s always air around them. This allows clarity to always be apparent even in the busiest of arrangements. Transitioning from there is a rise around 1-2kHz, where the majority of the FIBAE 4’s midrange energy is focused. This gives instruments a solid body, so despite the neutral positioning, they never lose their integrity.

    FIBAE4-5-7-W.jpg

    In the upper-midrange lies the FIBAE 4’s most audible colouration: A 3-4kHz dip. It’s what pulls the instruments back for a more reserved, open profile. As mentioned, they more so resemble tiny islands scattered throughout the soundscape; modest in note size and in projection. This ensures the soundscape is never saturated with loud instruments fighting for attention. But, at the same time, I find it has the adverse effect of limiting dynamic range. Midrange instruments have a tendency of lacking impact and punch. This is especially true of brass sections, like those on Snarky Puppy’s Chonks. The drama from those horns projecting boldly in your face is diminished. But, at the end of the day, when you consider the bigger picture, it is a compromise necessary for the FIBAE 4’s v-shape to work, and one that others may enjoy regardless.

    Treble

    Despite the v-shape descriptor I’ve been using throughout the review, the FIBAE 4 isn’t as egregiously contoured as the adjective may imply. This is especially true of the top-end. The FIBAE 4 possesses a clean, crystalline top-end with tons of air and detail, but it isn’t as sharp and crisp as one might probably expect from such a signature. This allows the FIBAE 4 to maintain a neutral tonal balance that errs too far neither in one direction nor the other. And, it also allows the FIBAE 4 to maintain coherence. Top-end transients are never too distant from the harmonics of the lows, so there’s a unified feel to the FIBAE 4 that’s become less common in the new hybrid era. It performs with precision and speed; no more, no less.

    The top-end efficiently cuts without overdoing brightness or sharpness. Edges are refined, but never blunt or muffled. This comes from the top-end’s immediacy in both transient and decay. Notes appear out of thin air, then vanish just as quick. This is evidently showcased in David Benoit’s Cast Your Fate to the Wind, rife with extremely delicate hi-hat and ride cymbal work. All those tiny touches are rendered through the FIBAE 4 with stunning clarity, and a convincingly realistic timbre. The second part to that equation is the stable backdrop, courtesy of strong extension. Composure is something the FIBAE 4 is never short of, and the same can be said for left-right separation. Stereo spread is downright out-of-head with the right material, and thus completes a wonderful top-end response: Clean, smooth, precise and full of technique.

    General Recommendations

    The FIBAE 4’s lightly-contoured frequency response makes it an exciting, clean-sounding monitor ideal for a number of genres, as long as you enjoy lots of openness, clarity and air. Above all, though, here are three things it does very well:

    FIBAE4-5-4-W.jpg

    Tight, clean and open-sounding instruments: The FIBAE 4’s airiness comes from its clean, well-defined instrument timbre. Images are crisp and well-outlined, which results in strong separation. And, great stereo spread places them all around you in convincing fashion. If you like light and fast instruments that don’t exude too much warmth, the FIBAE 4 is for you.

    A guttural, full-bodied low-end with clarity: A great balance between heftiness and definition runs throughout the FIBAE 4’s lows. Although its inherent timbre is airy and clear, it carries tons of weight in its impact due to clever tuning and strong extension. This is especially ideal if you’re playing or monitoring kick drums, or you simply want them to pop in the mix.

    Smooth, delicate yet crystalline highs: The same balance between finesse and cut exists in the FIBAE 4’s top-end. Notes cut through with airiness, refinement and clarity, yet they remain smooth and feathered in texture. These aren’t shrill, brittle highs that cut through the mix by force. Rather, they’re speedy, refined transients with a forgiving, effortless sense of air.

    FIBAE4-5-9-W.jpg

    However, to achieve its effortless clarity, the FIBAE 4 certainly has its fair share of compromises. It’s not the wettest, warmest or most intimate in-ear monitor out there. Here are three attributes in which those colourations most lie:

    Intimate-sounding, rich, warm mids: The FIBAE 4’s midrange is decidedly dominated by air. Instruments aren’t the most full-sounding, nor are they forwardly-positioned or intimate. They’re sat neutrally in order to emphasise spaciousness. So, if you prefer your instruments warmer, richer and more in-your-face, the FIBAE 4 may not be the ideal pick for you.

    Impactful, dynamic upper-mids: This airy sensation is most prevalent in the upper-mids. If you’re a rock aficionado – or a concert go-er in general – instruments like electric guitars and horns won’t have that visceral, dramatic sense of impact. Rather, they’re slightly restrained to avoid saturating or congesting the image; limiting dynamic range as a side-effect.

    Ultra-crisp and bright transients: The FIBAE 4 is only mildly v-shaped; particularly in the highs. The FIBAE 4’s top-end is crisp and articulate, but feathered and linear relative to the mids and lows as well. It’s a balanced presentation that may lie more towards the modest side to some, especially if you’re a treblehead looking for ultra-crisp, ultra-bright transients.

    Select Comparisons

    Custom Art FIBAE Black (€450)

    The FIBAE Black is slightly warmer and denser-sounding than the FIBAE 4. Its instruments are unified by a very light whiff of warmth, while the FIBAE 4’s are more separated, airy and tight. Though, in midrange projection and vibrance, they are very, very similar. What then makes the FIBAE 4 the more energetic of the two is its sparklier treble. Presence along 5kHz and 8kHz give the FIBAE 4 a brighter, crisper edge. But, in terms of overall quantity, the FIBAE 4’s top-end isn’t too much greater than the Black’s. So, they can both be considered equally linear and realistic, despite lightly differing tonal hues.

    FIBAE4-6-11-W.jpg

    Technically, the Black puts up a great fight. Its stage is wonderfully stable, well-defined and expansive. When it comes to background blackness, the Black does win out a hair. However, the FIBAE 4 has the edge in resolution and tactility. When you listen to hi-hats and ride cymbals, although they may be heard on the Black’s just as much as they are on the FIBAE 4, the latter’s reproduction sounds more tactile and corporeal. The Black loses a tad of integrity further up the range to the FIBAE 4. This is also because of the FIBAE 4’s more recessed lower-mids, which gives its notes more definition, clarity and contrast. This is what allows instruments like those to jump out at the listener more effectively, and boost realism.

    Custom Art FIBAE 2 (€475)

    Compared to its sibling, the FIBAE 2 is a more upfront-sounding monitor with a greater midrange emphasis. Images are larger in size and richer in timbre, assuming a more wall-of-sound presentation. However, this intimacy also comes from a significantly smaller soundstage. The FIBAE 4 expands far further, especially in terms of width. It also achieves stronger stereo spread with a more convincing surround sound sensation. Tonally, the FIBAE 4 is the cleaner-sounding of the two with tighter, faster, crisper and airier notes. It wins out by a sizeable margin in terms of resolution and transparency too.

    FIBAE4-6-13-W.jpg

    The FIBAE 2’s lows are richer, darker and fuller than the FIBAE 4’s more concentrated hits. Nevertheless, the latter wins out in physicality and slam because of its superior extension. Texture more easily comes through as well. The same goes for the top-end. The FIBAE 2’s comes across more blunted. Although its top-end extension is fine for a dual-driver IEM, it simply can’t compete with the FIBAE 4’s. This is shown in the latter’s far cleaner, stabler and more transparent stage. If I were being honest, the FIBAE 4 beats out its younger sibling in just about every technical regard by a clear margin. If you own the FIBAE 2 and you crave leaps in cleanliness, resolution and imaging precision, the FIBAE 4 is a very strong option.

    Custom Art FIBAE 3 (€525)

    The FIBAE 3 is a closer competitor to the FIBAE 4 both tonally and technically. In terms of sheer size, the two aren’t far off. However, the FIBAE 4 has the more proportional stage. Its expansion in terms of width and depth are near-equal, resulting in a near-perfectly spherical sound field. The FIBAE 3 is noticeably wider than it is deep, which results in lead instruments that are more upfront and panned instruments that sound further away. This gives the FIBAE 4 the more believable surround sound experience; immersive and realistic. The FIBAE 3 meanwhile comes across a touch more flat.

    FIBAE4-5-12-W.jpg

    In the lows, the FIBAE 4 is a touch meatier and more impactful. The FIBAE 3 perhaps has a hair more sub-bass content, but it really is splitting hairs as far as bass quantity is concerned. What is clear though, is that the FIBAE 4 is the victor in terms of bass extension, as the lows there possess a more realistic sense of slam. The FIBAE 3 possesses a more vibrant upper-midrange that gives it a touch more musicality than the FIBAE 4, while the latter’s more laid-back approach gives instruments more depth and air. The low-treble is the clearest discrepancy between the two. The FIBAE 3’s strong 5kHz dip will sound diffuse without proper adaptation, while the FIBAE 4’s is more tactile, coherent and realistic-sounding.

    Verdict

    The FIBAE 4 is Custom Art’s most impressive technical effort yet: Clean, vast and precise in imaging. At the same time, it’s Piotr’s most cleverly-tuned piece as well, getting away with more guiltless colourations than my hands can count. From a hefty yet airy bass, to a smooth, feathered yet crystal clear treble, the FIBAE 4 pulls off its many balancing acts with great finesse. Admittedly, its upper-mids were less successful; slightly unexciting dynamically. But, besides that – and with the tech and asking price in mind – this in-ear is quite difficult to fault. With the FIBAE 4, Piotr has given us his interpretation of a mainstream sound, and – in true, time-tested Custom Art fashion – it’s as clever, unique, balanced and refined as ever.

    4.5/5,
    Pros - Very good sub and mid bass, with good textures and natural decay
    Epitome of fun yet fatigue free tuning, with strong technical foundations
    Very good soundstage, with good height and depth
    Superb build, fit and isolation
    Very good value for money, a top notch competitor at the price
    Cons - A little more lower treble energy would have made the F4 even more fun
    Disclaimer
    I have purchased and paid the full retail (but nice pre-sales) price for the FIBAE 4, this is not a sponsored review.

    Review notes
    This review is based on over a 100 hours listening to the FIBAE 4, with various sources : AAW Capri cable for iPhone, iFi Micro DSD Black Label amp and DX220 with both AMP1 mK2 and AMP9. As usual with FIBAE IEMs, the FIBAE 4 signature is consistent across sources. My preferred combo is DX220 with the NuTubes powered AMP9. I tried several cables but PW 1960 4 wires and PlusSound X series were my favorites


    Packaging
    The FIBAE 4 in custom form comes with a solid black plain card box which contains a black Pelican 1010 hard case with a transparent lid itself containing a small blue pouch with a cleaning tool.

    Specifications
    • Single low, Single full-range, single proprietary high, single proprietary super high
    • Sensitivity : 115dB @1kHz @0.1V
    • Distorsion : Low % THD
    • Impedance 8.1 Ohm @1kHz (+-0.95 Ohm 10Hz-20kHz)
    • Frequency range : 10Hz-21000Hz (+-20dB into IEC 60318-4 coupler)

    Introduction
    2019 will be Custom Art’s year for sure, as they pushed the envelope starting with the FIBAE Black release a very singular single BA with a Helmholtz resonator which also happened to be my first Custom Art IEM. The FIBAE 4 is another release this year and innovating as well with the first to include 4 BA top firing drivers. As stated on Custom Art’s website « Top Firing Drivers provide improved frequency extension compared to traditional Balanced Armature drivers with a spout resulting in immensely detailed sound».

    I loved the FIBAE Black so much (which holds a unique place in my collection with its distinctive and intoxicating tuning) that I didn’t wait for reviews and enjoyed the preorder price making it a very attractive and refreshing proposition in a soaring prices market. No brainer.

    The FIBAE4 tuning was quite appealing to my tastes as well : « We tuned FIBAE 4 to be fun sounding IEM with warm and smooth signature. It offers excellent sub-bass depth and punch, detailed and natural midrange finished with extremely detailed, but never harsh highs. It combines big headroom, high resolution and expansive sound stage. FIBAE 4 is a perfect tool for guitarists, bassists and drummers for stage monitoring. »

    Does it hold its promises?
    Let’s see !

    Fit, Build and isolation
    The FIBAE Black was the first Custom Art model introducing 3D shell printing and it also was one of the best fit I ever had with customs, no matter which price point. I was very confident that the fit would be perfect and it is indeed even better than the Black in the sense that it’s just slightly less tight while retaining a perfect seal. Isolation is better than my other custom because the seal is just a little bit tighter than my other customs (VE8, Phantom and EM64 which is based on the same digital impressions). Wearing a Custom Art IEM is a fatigue free experience for sure.

    The build is simply perfect, and the FIBAE4 looks sturdy to withstand every day use.

    I chose a full black shell (required for 3D printing) and stuck to black plate, plain if you will. There are benefits when commutting not to attract attention, although the brand is able to provide mouth watering art on their shells, and I think when I get the FIBAE7 I’ll pick something sexier :p

    9FEF8706-69FB-4F50-818D-2D6A457AD7E2.jpeg

    Sound
    The FIBAE4 is a very dynamic IEM that manages to remain absolutely smooth across the range, thanks to a softer attack and a very nuanced presentation.

    It is deeply grounded in bass with very good sub bass extension with good extension and beautiful textures, providing a lot of fun and great rhythm for a toe tapping experience. Interestingly Custom Art decided to keep the mids fairly neutral with good clarity and articulation, vocals are very natural and with good presence. Treble has very good extension providing welcome air with a very natural decay, probably a benefit of the top firing drivers.

    Its signature grants the FIBAE4 a very good and balanced soundstage with good height and great depth, with very good layering. The overall sense is a highly coherent fun and smooth fatigue free signature. A fun tuning for sure but a mature and refined one too.


    Bass
    I expected the FIBAE4 to be a fun bass experience and it is indeed but without sacrificing technicalities. Typical of modern BA bass implementation, the FIBAE4 features big BA bass driver that is able to hold its own against good dynamic drivers, especially in terms of texture and - probably a benefit of its top firing driver - a very natural decay that offers a sense of realism that few BA can brag about.

    Sub bass extension provides the oh so very pleasing hit of subs. The attack is on the softer side, providing kick without being fatiguing. It boast a lot of detail and never gets saturated. It’s somewhat reminiscent of how my former 64 Audio U12 portrayed bass, only the top firing driver is at work there instead of an ADEL module and is true of the whole bass range as well.

    Mid bass has good presence but it manages to stay clean and controlled something IEMs in the same kind of tuning don’t always do so well. Again, it’s a mature tuning and an audiophile take on the fun well extended subs combined with great mid bass presence. It certainly does help the soundstage depth to have a more progressive decay.


    Mids
    The FIBAE4 mids is where all of its seriousness is revealed, for it’s very balanced and natural. I don’t find the FIBAE4 to be that warm despite the product page claim of warm and smooth. The warmth is inherited from its mid bass rather than its mids. Mid centric tracks will reveal the FIBAE4 to be quite accurate in terms of tone and timbre, and closer to neutral with just a touch of warmth to fall into the natural category.

    The lower mids are lean and clean, with enough presence to grant its mids body but not enough to color them too much. Vocal presence is really good, male vocals do shine and female vocals are just a little sweeter than pure neutral which I don’t mind at all. Textures stand out and instruments are portrayed with a lot of realism.

    Last but not least - given its signature this balances things nicely -the FIBAE4 have good upper mids presence which grants a very good level articulation and separation, while remaining buttery smooth. Bass and treble are what makes the FIBAE4 stand apart but its mids stay true to the Custom Art philosophy as smooth as can be while retaining very strong fundamentals and technicality. A real treat!

    Treble
    Despite the prominence of its bass, the FIBAE4 treble is key to its signature and with the support of two custom BA drivers. Good treble extension is definitely a factor in both soundstage providing welcome air and good resolution and a deceptive ability to retrieve the fine details. In this sense upper treble is really the highlight point of the FIBAE4 treble wise, and while it takes a step back to the bass it plays a very defining role in the signature. Lower treble is less prominent and I wouldn’t have minded a little extra energy there, but the benefit is an absolutely non fatiguing signature.

    0CBC470F-EAB4-4D7D-8BF8-083D65B89925.jpeg

    Verdict
    There is no mistaking a Custom Art IEM, and the FIBAE4 is definitely not breaking the common rule : it has this smoothness and musicality that is so characteristic of the CA house sound.

    It would be tempting to categorize the FIBAE4 as a U shaped signature, but I never really dug the concept of V, U or L shaped as I find them too reductive and there is much more to an IEM signature than it’s frequency range distribution. While the bass and upper treble clearly are the foundation of the FIBAE4 signature, its mids have good vocal presence and instruments are not recessed either and it’s why I think it’s a good all rounder. On top of this, the softer attack and natural decay plays a key role to the sense of realism and naturalness of the FIBAE4.

    If you’re looking for a fun IEM with sound technical foundations that you can listen to for hours at times without any fatigue, then the FIBAE4 is definitely a must own in a collection especially in its price bracket! If you’re looking for fun tuning with more bite and a snappier attack then there are a few mid range IEM that could suit you more like say Earsonics Velvet v2 or - more pricey - the Earsonics Purple or Campfire’s Atlas.

      @jeffhawke Good point, I am a bit lazy on vacations there :p I’ll try to add some comparisons later, I don’t own many mid range IEMs but I’ll sure add a FIBAE Black comparison.

      As a matter of fact, the Black is exactly the one I'm interested in comparing to the Fibae 4. I'm in the difficult and time consuming process of deciding which should be my first CIEM, and I'm sort of leaning towards the Black, but still very undecided.
