Preamble
Many thanks to @Damz87 and @EffectAudio for arranging the Australian tour of the Gaea as well as the Ares 8W, Cadmus 8W and Code 23.
The audio world is quite partial to a good collaboration. From influencers stamping their name on the latest and greatest of chi-fi, to Astell & Kern putting their spin on various IEMs over the years and to musical artists themselves collaborating at length to the point of their names being synonymous with one another. These collaborations can lead to a hit leaving their audiences begging for more, or simply fade away with a whimper.
And so, what comes when a Malaysian manufacturer of IEMs combines forces with … a cable maker? Before you query that, Effect Audio (
EA), whilst known for their cable laying capabilities, have had previous forays in the IEM market with their Axiom and having a previous collaboration with QDC.
The Gaea is a collaboration of what seeks to be a long-running relationship between Elysian, often known for their TOTL, the Annihilator and EA who have been ubiquitous in the cable space.
The Factual Stuff
The Gaea tour kit does not contain the original packing and so I was treated to a rather abridged unboxing experience to reveal a clamshell carry case containing some Spinfit W1s, the Gaea earpieces and a EA cable.
The Gaea earpiece themselves are fashioned out of resin and stabilised wood finished in a handsome blue hue. The EA cable is of four-wire construction and consists of a blend of copper and silver plated copper. The cable features some nice hardware featuring the same stabilised wood finish and has two of the four wires finished in blue.
Within the Gaea’s earpieces lay five drivers consisting of a single dynamic driver and four balanced armatures. Whilst not listed on the product listing, it appears that the Gaea has the DiVe pass system venting the housing to avoid pressure build up as well as driver flex.
All of this comes in at a price range of around 1300 USD.
The Opinion Stuff:
Sound
Bass:
The bass regions of the Gaea present with what I would describe as a clean tonality. The bass regions are well balanced with the rest of the frequency response and there is a decent amount of it to keep you rather engaged with the experience. The Gaea is not winning any awards for the most bassy IEM in the market nor is it copping any flack for being anaemic in this region.
Sub-bass seems to be the star of the show here the thumpy lower regions presenting with a robust enough body to keep you engaged with modern pop songs. “Seven” by Jungkook has a rather fast thumping bass line throughout the initial verse that gets even deeper and more drawn out in the chorus. The Gaea handles this excellently with the authority and speed required whilst maintaining enough separation from the mid-range as to not step on any toes.
Mid-bass is also very cleanly done with a minor boost that seems to give it a punchiness that is absent from more strictly tuned IEMs such as the Variations or the Helios, “Out of Time” by the Weeknd has a tendency for the bass drum to overlap with male vocals in a manner that overly colours the vocals, this is not the case with the Gaea. Yet it still handles old-school sample beat that is lush with any IEM with good mid-bass going.
Overall, the bass region is done in a manner that presents music in a manner that retains its fun factor whilst not overpowering the midrange or presenting an coloured warm tonality to the rest of the frequency response. There is likely not enough to please bass-heads but overall, I feel that this region is inoffensive and very well done.
Mids:
The midrange of the Gaea is, in my opinion, a slightly mixed bag. It undertakes a slightly lifted tilt up into the upper-regions and has a slight tendency to sound and feel slightly thin in its reproduction.
Male vocals such as “Leave the Door Open” by Silk Sonic present cleanly with no overstepping mid-bass diminishing clarity but there is a sense of reduced weightiness to certain male vocals. Clean and clear yes, but there is a sense of missing emotion and natural timbre to this region. Songs such as Grover Washington’s “Just the Two of Us” presents the vocals of Bill Withers as rather recessed in the mix. Female vocals such as “Dreams” by Fleetwood Mac presents female vocals with a shimmery and ethereal quality that injects a sense of airiness and sparkle that is addicting in a way. I would not say that this is a natural reproduction of female vocals but a very pleasing one nonetheless.
Attempting to draw out some sibilance, I chucked on “4 walls” by f(x) which has an abundant of sss noises sung by heady female vocals and the result was rather harsh at times. This is inevitably an attempt to trip up the Gaea and it skewed a bit too far in the bright region for me. Otherwise, instrumentalization within the region presented with a great crispness and cleanliness that tickled the eardrums. “The Chain” by Fleetwood Mac, the dobro and guitar feel visceral in their presentation, sprinkled with the overlapping male and male vocals, the result is a song in the Gaea’s wheelhouse. Where the Gaea faces some difficulties is the presenting a more emotionally engaging presentation of music as it comes across as slightly tinny and thin at times.
Overall, the Gaea presents female vocals with uniquely addictive quality and instruments receive a rather good dose of crispness and clarity with this tuning. There is a slight loss in note weight, natural timbre and some emotion in this reproduction but I believe it handles it far better than the likes of the Variation or the Helios.
Treble
The upper regions of the Gaea present a rather bright leaning tonality. The airiness and sparkle of the Gaea is something that cannot be denied with certain percussion presenting in a forward and easily discernible manner. Hi-hats that emanate through songs such as “edamame” by bbno$ hit with a crispness and clarity that provides a slight tingle to the eardrums, brushes against hi-hats in “The Demon Dance” by Julian Winding provides a wonderful contrast to the dark and moody nature of the song. However, it is not all subtleties with the Gaea, more extremely produced songs such as the piecing synths in “You & Me (Flume Remix)” by Disclosure and Flume are sibilant and somewhat harsh in their sharpness. The treble region seems to inject a sense of openness and crispness to the entirety of the frequency response, with the Gaea reproducing with some airiness to its tonality. Extended listening periods with the Gaea led to a sense of fatigue after some time, expounded with certain strings of EDM tracks. This was less of an issue with more acoustically focused tracks in my playlist but nonetheless, the Gaea required some breaks from time-to-time in order to relax from the rather bright leaning tonality.
Overall, the Gaea seems to elevate a sense of detail, crispness and sparkle in its frequency response as a priority. I don’t particularly mind this tuning given my relative lack of experience with brighter IEMs but ultimately, I can see why such a tuning would be divisive. At its best, the treble is a very rewarding experience, with the goosebump inducing reproduction of certain production providing you with a tremendous sense of drama but this is not an IEM that you can sit back and relax with as it seems to attack you with this region.
Technicalities:
There was little to sense of wanting in the region of technical performance. The aforementioned tuning seems to heighten microdetails and injects a healthy sense of air into the Gaea, presenting itself as a readily coherent IEM.
The resolution of the Gaea is inflated on more casual listens as cleanly tuned nature of the bass and lower-mids leading into that rather healthy upper-mid and treble boost presents a leaner and thinner reproduction of instrumentalization and vocals that presents itself as “faux-resolution”. There is nothing wrong with this, as long as you are agreed with the tonality as a whole.
Staging is a bit of an odd beast to tack down with the Gaea. I don’t believe that it stages too far wide nor deep but rather presents music in the head-stage in a manner that is like a bubble slightly outside the head. Perhaps by virtue of that brighter-tilting tuning combined with its sense of airiness, there is a sense of a set of speakers in an intimate room.
Imaging within this stage is similarly good, tracks such as “Fine” by Taeyeon images a set of overlapping voices at approximately 2:30 in a manner that allows you to discern the voices from one another, but unlike more capable IEMs that allow you to state “one voice is at 1 o’clock and the other is at 3 o’clock”, the Gaea does not provide this. However, it is not all bad, the aforementioned airiness of the Gaea presents music in a cleanly separated and layered manner. In doing so, it allows the listener to dissect their music as each instrument and vocal line seems to sit on their own plane yet all coming together in a coherent and enjoyable manner.
Overall, I feel that the Gaea receives a lot of help from its tuning in terms of technical performance and for that I applaud Elysian and EA for executing this tuning in a manner that remains enjoyable (to me) and elevates detail.
Overall:
Bright leaning, the Gaea isn’t necessarily the everyman IEM but remains distinctly enjoyable in my books with its rather aggressive reproduction of upper-mids and treble. Somewhat untenable for those who are treble-sensitive or are looking for a laid-back listen, the Gaea presents sparkle and tingle inducing percussion in spades and doesn’t dispense with a good bass response or mid-range as a cost. The tonality leans somewhat bright and potentially metallic in its timbre at times but clear, concise and sparkly is a rather unique experience.
Synergy
One thought coming to my mind here namely lessons learnt after multiple DAPs, DACs and Amps plus headphones and IEMs is synergy!
Hoping for the one and only holy grail Setup is maybe just a nice wish unless buying according synergy transducers.
There's a reason why people are having multiple devices in parallel or reducing inventory and keeping only the ones with right synergy
Shanling M6U
I would characterise the M6 Ultra (M6U) as a smooth, slightly warm source with an increased sense of presence in the mids and a strong note weight.
The Shanling M6U counteracts some of the gripes that I have with the Gaea, with the M6U imparting warmth and some weight to the midrange. The result is a more full-bodied form of the Gaea in a subtle manner. The previously clean and clinical bass got a little more oomph in the mid-bass and vocals and instruments were no longer as flighty and light in their presentation. However, these changes are minor at best and at worst, negligible for those who aren’t listening critically and A-Bing their sources. As such, the M6U represents a bit of an odd pairing synergistically in that it does not lean into the tonality of the Gaea but rather counteracts it somewhat, leaving a more confusing sound signature that isn’t really sure what it is. It takes the edge off a little but ultimately is not a good pairing for me.
Mojo 2
I would characterise the Mojo 2 as a very, very slightly warm neutral tonality with a more natural reproduction of instruments and voices with no DSP enabled.
The Mojo2 presents a rather straightforward reproduction of music with the Gaea, there is a sense of reduced weight from the M6U and a greater clarity in music. I do not believe that the Mojo2 and the Gaea leans to too far into the thin territory but rather meshes quite well, especially with the consideration that you would be able to alter the Gaea with EQ.
The bass response feels nice and fast, with less mid-bass than the M6U perhaps less of a slight treble uplift as it felt not as sibilant with songs that sought to bring that out.
The Gaea’s synergy with the Mojo2 is something that is not particularly outstanding in any regard and in this respect I hesitate to make any sort of strong statement. The Mojo2 and the Gaea work fine together.
iBasso DC04 Pro
I would characterise the DC04Pro as dynamic, clean and has a very low noise floor. The sound signature is slightly bright in comparison to my other sources and tracks seem to “attack” you.
The DC04 Pro seems to close up the staging of the Gaea, creating a more intimate experience wherein sounds seem to be confined within a phone booth rather than a recording studio. This experience may seem detrimental but there is an added energy to music which when combined with the DC04Pro’s exceptional noise performance seems to attack you with sounds out of the blackness of silence.
This combined well with the Gaea providing less of a diffuse staging wherein clarity and separation were key points of emphasis but rather providing a more engaging and dramatic reproduction of music.
Where the DC04 Pro suffers is the perceived brighter tilt of the source versus the M6U or the Mojo2 and when working with an already lifted upper range on the Gaea, seems to enhance a sense of sibilance when listening to more harshly produced songs.
In this regard, I believe that the DC04 Pro is a rather good choice if you want a more engaging listening experience and don’t seek to have an analytical breakdown of whether you can make out a hi-hat at 2:35 of a particular song but rather want to be engaged by simply letting the music wash over you.
Cable MADNESS
The Gaea kit came with an assortment of cables, including the Ares 8W, Cadmus 8W and Code 23. I also was lucky enough to receive the Fusion 1 tour at the same time, as well as the Diva (review coming soon) with the Ares 4W and the very lovely
@GiullianSN provided me with his personal Cleo II Octa for the following cable rolling experience.
Ares S
The entry level of the latest series of EA audio cables, the Ares is four wires of pure copper construction. The combination of the Gaea and the Ares S is a distinct sense of taming the upper regions of the frequency response, sibilance is seemingly reigned in, the bass becomes slightly more boomy and there is a slightly slower decay imparted on the Gaea. These seek to enrich what is a rather clinical IEM with some more lushness and in that regard it does so with little finesse. The stage does not feel that deep and the appeal of the Gaea is held back slightly as it is darkened by the Ares S. Overall, it fixes some problems but is as precise as a mallet in this regard and I believe some of the nuances of what makes the Gaea special is lost with this pairing
Ares S 8W
Its smaller brother didn’t fair too well but the 8 wire version seems to be better. Compared to the 4W and stock cables, the Ares S 8W seems to bring the female vocal more forward in the mix and there is a seemingly greater sense of depth to the stage. There is a boomy sub-bass throughout my testing and slightly more mid-bass. Sibilance is somewhat still present but reigned in from the stock and ever so slightly more spicy than the 4W equivalent of this cable. There is a perceived loss in ‘energy’ with the 8W cable as it seems more slow in the decay of certain notes and combined with the boomier bass creates a sense of lethargy.
The perceived improvements in staging and the slightly more nuanced approach to the Gaea’s FR seems to work well and I believe that this is a better choice than the 4W version.
Cadmus 8W
The Cadmus’s silver plated copper construction leads to a number of nuanced differences from stock and the aforementioned copper cables. There is a perceived increase in the depth of stage, and contrary to popular belief, there appears to be a reigned in upper-mid and treble region. Bass quantity is reduced from the Ares brothers but it remains distinctly fast, detailed and textured in its reproduction.
Overall, the Cadmus seems to heighten the characteristics of the Gaea ever-so-slightly and presents what I experienced with the stock cable but turned up a few notches. Not the most dramatic difference but if you already love what you get with the Gaea and its stock cable, the Cadmus seems to be a % point improvement that might be worth it.
Code 23
This cursed ergonomic beast features a rather thick copper core surrounded by various wires of varying materials. The result of this is a greater width and depth to the stage, the Code 23 feels distinctly the most spacious of all the cables in this round up. Otherwise, the bass feels more generous in its quantity with booming sub-bass being handed out in spades. However, there is a slight slowdown in the bass that feels somewhat disappointing. However, the strongest capability of the Code 23 is the perceived improvements in technical performance and the increased sense of imaging. Instruments and vocals are separated clearly and allow for a greater sense of immersion in your music. For this reason, I believe that the Code23 is a rather unique choice for the Gaea and one that I do not believe would be a bad choice.
Fusion 1
A gorgeous gold cable featuring every material in the book with its 2 wire construction. The combination of the Fusion 1 and Gaea seemed to present a more vocal forward reproduction and a great enhancement of spaciousness. Perhaps not the level of the Code23 above but definitely within the upper range of this assortment of cables. Speed returns to the bass and it remains distinctly punchy and fun. It is faster than the likes of the Code23 and both Ares and is perhaps similar if not the same as the Cadmus. However, unlike the Cadmus, the bass remains readily apparent and quite fun in its boominess.
I believe that the Fusion 1 presents the best all-round approach to the Gaea but note that there is a slight sibilance that remains with the cable.
Cleo II Octa
A pure silver 8 wire cable, the Cleo coalesces with the Gaea in a manner that is rather excellent. The staging capabilities compared to the likes of Fusion 1 and Code23 seems lsightly more confined but there is a sense of energy imparted to the Gaea. Bass is punchy and quantity is not lacking, sibilance in the upper mids/treble is reigned in and the perceived sense of imaging and resolution of more subtle notes in songs seem to be heightened. The Cleo, like the Fusion 1 seems to be on the best all-rounders that do not seek to overload a certain region nor take away too much. In this case, I believe that the Cleo II is a fine choice for a combo with the Gaea.
Comparisons
Vs MEST MK2
The MEST MK2 presents music with an emphasis in sub-bass and in the upper treble. Mids remain fairly neutral but come across as slightly thin at times. The MK2 and the Gaea share some similarities in the treble but where they differ substantially is in the upper-midrange section wherein Gaea seems to place more emphasis on vocals and eeks out some shrillness whereas the MK2 comes across as decidedly more relaxed.
Where they differ most is perhaps the technical capabilities and the way in which music is presented. The MK2 seems to take a more even approach to balancing instruments and vocals and does so with its odd “3D” soundstaging capabilities. The Gaea injects a large amount of air and upper mids into the mix in order to create a sense of space between certain instruments but there remains a distinct forwardness of vocals.
The latters tuning seems to help with perceived resolution but overall, I would give the nod to the MK2 for resolving busily produced tracks with ease in a more natural manner than the Gaea.
I feel that the MK2 represents a more balanced and approachable tuning and has the benefit of having that special sauce bone-conduction driver that seems to add a level of depth to your music.
Vs Diva
The Gaea’s bigger brother is the next step in the Elysian line-up, and whilst it is more expensive, it is not hugely so. The Diva has some similar traits with the Gaea in terms of its upper-mid lift leading to a forward vocal presentation. However, the Diva differs in a sense of added lower-end weight and warmth that creates a far more laid-back listening experience that is thoroughly enjoyable. The Diva’s treble also seems less aggressive and more smooth in its reproduction. The end result is a vocal forward IEM with the edges rounded and smoothed out as opposed to a fastidious and hard-edged approach of the Gaea. I definitely enjoy the Diva more for its more naturalistic and engaging presentation of music as well as the granularity in the bass-tuning switch. But the bass also is an oddity with the Diva having zero dynamic drivers compared to the Gaea’s single DD. Conventional thinking would have you believe that the Diva’s bass doesn’t hold a candle to the Gaea’s but I don’t believe that to be true. In terms of technical ability, the Gaea sacrifices timbre in the pursuit of what I term “faux detail” whereas the Diva retains detail and resolution despite its smoother and more warm production and in this regard, I would give the nod to Diva. The Diva doesn’t seem to project as spacious of a stage as the Gaea owing to its rather intimate vocal presentation which seems to eliminate any perceived extension in terms of width.
The Diva presents the Gaea’s female vocal speciality in a different context which is for me, is much more enjoyable. As such, I give the Diva the nod here but understand those who want a hard-edged and drier reproduction of music would prefer the Gaea.
Vs Helios (from memory and previous review)
The Symphonium Helios is an IEM that I characterised as being somewhat thin and with an excellently executed treble region that extended high and was done without becoming fatiguing. The Helios, in my mind, represents the best comparison for the Gaea and I sought to see who won out.
The Helios has a lower-mid dip that does a great job of separating the bass from the mid-range but at the cost of severely diminishing anything that sits in this region and imparting a clinical coldness to the frequency response. The Helios lacks note weight and can be a little too precise in its reproduction of music to the point of reducing my emotional engagement with my music.
The Gaea has some elements of this but the drama and the excitement is retained well with its nice bass which hits slightly harder in the mid-bass region, creating a fun-factor that was absent in the Helios. The treble on the Gaea is less smooth and more peaky compared to the Helios and I would venture to say that it is far more likely to cause fatigue over time.
Overall, the Gaea has some of the traits of the Helios but presents its sound signature in a more enjoyable manner in my opinion. The Gaea, in my opinion, presents a better all-rounder compared to the Helios.
Value & Quality of Life
At 1300 USD, the Gaea is against some steep competition in the kilobuck range. When compared to the aforementioned IEMs in the Comparison section above, I do not believe I would be incorrect to say that the Gaea is a fine choice for this price, however, I do not believe it is the safe choice for this price bracket.
It leans on the thinner side of tonality and slightly brighter than its competitors and in this regard, I do not believe it to be the “everyman” IEM.
The included accessories in the tour kit are rather skim but the inclusion of a EA cable with the ConX system is a rather good inclusion. However, points are taken off as the cable doesn’t appear to be a TermX compatible cable. The cable uses a Pentaconn connector for the IEM-side connection (P-Ear) which feels to be a better executed form of MMCX. The cable slots in and is removed easily using a guiding pin to ensure that you are not inserting it at an angle. This is a great connector in my mind as it allows freedom of movement (a win over 2 pin) and feels far less fragile than MMCX. However, the issue is that it is a rather rare connector and for those with a collection of cables may feel disappointed.
The earpieces themselves are lightweight and well-made, the combination of which seem to be a comfortable fit for myself and likely a large proportion of the market. The depth of the earpieces are fairly robust and as such may pose some problems but these fit in and stayed in my ears with little to no issues over longer listening periods.
Overall, the combination of ergonomics and the sound quality that you get from the Gaea lead me to believe that this is a rather good choice on a technical and liveable standpoint but a gamble tonality wise.
Conclusion
The Gaea is a rather bright and thinned out IEM that seeks to heighten a sense of space and air throughout the listening experience. It achieves this in spades and provides a rather unique experience. However, unique doesn’t necessarily mean excellent and whilst I can appreciate the Gaea for what it is, it is tonally out of my wheelhouse and do not believe it would be a very versatile IEM.
For those who are sensitive to treble and for those who enjoy warmth in their mid-range, the Gaea is the one to avoid.
Overall, I would not mind the Gaea in a rotation of IEMs to which I could appreciate more open productions of music and to feel a sense of goose-bump inducing excitement with treble from time-to-time but as a standalone IEM, I believe that it fails to provides a sense of weightiness and emotional impact that I am looking for. It is clean and clinical with a bit of spice in the top end for that added drama.
