Introduction:
Elysian Acoustic Labs is a well-known, high-end IEM manufacturer based in Singapore. Last year, I was fortunate enough to get the opportunity to review three of their IEMs: the Annihilator, Diva, and Pilgrim. So far, I haven't fallen in love with any of the Elysian offerings I've reviewed, but I was able to demo the Apostle at CanJam SoCal 2024, and it left a positive impression. This model utilizes a tribrid driver configuration consisting of a single dynamic, two balanced armature, and two electrostatic drivers and comes with a price tag of $1800. Let's break down the Apostle and see what it has to offer.

Build, fit, ergonomics:
The unboxing experience is nice, although I don't find it exceptionally premium or worthy of the $1800 price tag. The black packaging also feels a bit too boring from a design standpoint. The Apostle's shells are made of aluminum alloy and have a great build quality and premium feel. They are a dark gunmetal gray with black metal accents on the faceplate featuring the Elysian logo. The shells are somewhat contoured and are on the larger side, unsurprising for those familiar with both the Annihilator and Diva. They have a really nice weight balance—not too heavy or too light—and are comfortable to wear for extended periods. The insertion depth is about average, and the nozzle measures 6.3 mm at its widest point at the lip. The fit is adequate for my ear, but I would welcome a slightly longer nozzle. Vents located within both the Elysian logo and the arrow accent on the faceplate help alleviate pressure buildup. The Apostle, like other Elysian IEMs, utilizes the Pentaconn ear connection. I do like this connector type, but it is more niche, meaning it is harder to cable roll unless you already own other IEMs with this connector. The Apostle comes paired with Elysian's custom Flamberge 19 AWG copper, hybrid silver, and gold-plated copper cable equipped with a 4.4 mm termination. I didn't have any other compatible cables at my disposal, but luckily the stock one is decent quality, and I'm not sure I would feel the need to swap it out even if I had the option. The black cable is a little thick, which I prefer, but it's also a bit stiff and has some memory. The Apostle also comes with a full set of Divinus Velvet tips. I own some of these already and generally like them, but I preferred the Eletech Baroque tips, which provided the best seal and comfort for me. The quality of the puck-style case is just okay. It's lightweight and well-designed, but it feels a little cheap, especially for the price. I've seen much better quality cases accompany sets less than a quarter of the price, so this one is disappointing. The other accessories include two small branded cloth pouches to hold the shells, a cleaning cloth, and a cleaning tool. All in all, the Apostle's accessories are decent, but for the price, I think they could be better.

Sound impressions:
I would describe the Apostle as having a V-shaped tuning that is equal parts energetic and musical, with a deep bass response, mildly recessed midrange, and a slightly bright but not overzealous treble. The note weight is on the thicker side of average and hits the mark just about perfectly for me. As for drivability, this set doesn't necessarily need a lot of power to reach high volume levels, but like most IEMs with ESTs, it performs best with amplification. The detail retrieval is quite strong and is one of the better performers I've heard under $2,000. Subtleties and nuances of tracks are easily discerned, but without coming across as clinical or cold. The soundstage may not be the most expansive, but it still has an impressive sense of width, depth, and space and is far from claustrophobic. The timbre is quite impressive as well. It sounds very natural and organic and avoids any glaring issues. The imaging is decent, but not the best I've ever heard, though it's plenty accurate and more than sufficient for me. The dynamics is one area where I feel the Apostle could be a little better, though the tuning holds up pretty well despite the volume level. The separation and layering are both superb. It's able to navigate complex tracks with ease, and each frequency is allowed room to breathe, though it still has a very cohesive sound. All in all, the Apostle has one of the best balances of technicality and musicality that I've come across, and it's truly impressive.

The Apostle is definitely a source-sensitive set, meaning finding the right synergy is very important. For instance, the Questyle M18i is a great match for those who value bass texture and treble energy above all else. I can enjoy this pairing to a certain extent, but it's not really my preference as it can be a little bright and sibilant for me. The iFi GO link Max is a great option for ease of use, but it can also be a little too energetic at times. My synergy of choice is the Muse HiFi M5 Ultra in tube mode. The added warmth is welcome, and it plays up the Apostle's inherent musicality. It can also be switched over to transistor mode for when I want a little less warmth and a slightly more technical sound.

●Lows - I'll be frank, I find the Apostle bass far superior to the highly acclaimed Elysian Annihilator, but keep in mind my opinion is based on aural memory alone, so take it with a grain of salt. It's definitely more sub-bass focused, but there's still a good amount of mid-bass. The overall quantity is there in spades and it could be considered basshead level, but the quality is also impressive. The extension reaches very low, and the rumble on particularly bassy tracks is a treat. The decay is about average, which allows for plenty of bass reverberation, but I wouldn't mind it being a bit slower, letting notes linger a hair longer. There is no bleed into the midrange to my ear, and the speed is great. It's not overly fast, but definitely quick enough for those double bass kicks. There are some areas for improvement, though. The impact and slam are just adequate. Kick drums pop well enough and have a decent weight to them. However, they need to be more impactful to stand out, considering the amount of sub-bass. The texture is good, but I feel like it could be ever so slightly dirty or wet at times; however, I think that also gives it a certain charm, and it is still very enjoyable. The resolution could also be slightly improved, but, as I see it, the bass is more about the feeling it gives than being technical proficient. It's about making a connection with the music, and in this, it truly excels.

●Mids - Due to the nature of V-shaped tunings, the midrange is bound to be recessed in some fashion. In the case of the Apostle, the lower portion does suffer a bit, but there is more than sufficient pinna gain to allow vocals to shine. Speaking of vocals, they are clear, natural-sounding, and emotive, really a joy to listen to. There is also a depth and maturity on display that many sets try for but few achieve. I generally like a warmer and lusher midrange, even if it comes at the expense of bass quantity and treble energy and extension, but the Apostle manages to strike a great balance. It has a certain "have your cake and eat it too" type of midrange for me. There is sufficient energy in both male and female vocals while still having an emotive and musical quality to it. My favorite tracks come to life on the Apostle and vocals almost have an air of superiority to them. The midrange might just be my favorite aspect of the tuning, which is very high praise indeed. That being said, those who want the best lower-midrange instrument representation and reproduction may want to keep looking, although I believe it performs admirably enough in orchestral arrangements.

●Highs - Typically, EST drivers and I don't always agree. They tend to have a thin or ethereal quality compared to planars or BAs, at least to my ears. The Apostle, though, has an excellent treble response and is easily one of the best implementations of EST drivers I have heard to date. It's energetic and crisp, but not overly bright. The treble detail and texture are very well done and add to the Apostle's special tuning. The extension could be a little better, and I wouldn't mind a little more air, but it is sufficient for my preferences. Cymbals and hi-hats are crisp and natural without sounding splashy or metallic. Snares and claps are clean and precise without being incisive. There can be a little sibilance at times with "s" and "sh" sounds, as well as some other treble notes, but it is very source and track dependent. The Annihilator's treble was a bit too much for me, so I'm glad the Apostle is toned down slightly, bringing it closer to my preference. Pairing with a brighter source, though, can draw out a little more energy for those who want it. Overall, the Apostle's treble is very well done, and for a V-shaped signature, it gets the balance almost perfect.



Comparisons: Credit to Jaytiss and Atech Reviews for the graphs.

● Astell&Kern x Empire Ears NOVUS ($5000) - The NOVUS has a quad-brid driver configuration featuring 2DD, 5BA, 4EST, and 2BCD, compared to the Apostle's 1DD, 2BA, 2EST tribrid configuration. The NOVUS is a tour unit, so I only received the stock cable and case. I do like the NOVUS's metal case much better, and the cable is a toss-up, but the one accompanying the NOVUS is more pliable and softer, which I prefer. When it comes to build quality, the Apostle's shell feels a little heavier, is more sturdy, and is the smaller of the two. The NOVUS is quite large, but it actually fits my ear better, and I prefer its premium design and gold accents over the Apostle's more monochromatic aesthetic. When it comes to tuning, both are generally V-shaped; however, the Apostle is a bit more so, while the NOVUS has better balance across the entire frequency response. The Apostle is more sub-bass oriented, while the NOVUS strikes a good balance between mid- and sub-bass, with neither taking a backseat to the other. The Apostle's extension definitely reaches lower, and there's more rumble and reverberation, but the NOVUS has better detail, resolution, and texture. It also has a more impactful mid-bass punch, which is especially great for rock genres. In the midrange, the NOVUS better represents the lower range of instruments and is again the better balanced one. It also has instrument and vocal timbre that are leagues ahead as well as an openness and depth that the Apostle cannot match. That's not to say that the Apostle sounds congested, but it does have a further recessed lower midrange, which doesn't help. However, vocals are both more soulful and more forward on the Apostle, which I do prefer to the NOVUS' colder and drier-sounding vocal performance. As for the treble, the NOVUS is a little brighter and more incisive, with a touch more air and extension. It also has a slightly grainy texture, and certain "s" and "sh" sounds can be bothersome at higher volume levels. The Apostle has plenty of sparkle thanks to the ESTs, but it sounds tamer and more controlled compared to the NOVUS. When it comes to technicalities, the NOVUS is absolutely the clear winner in just about every discernible category. The Apostle is still impressive, but the NOVUS has more detail retrieval, a wider soundstage, more natural timbre, and better layering, separation, and imaging. The Apostle, though, does have a thicker note weight, which I prefer. In conclusion, both IEMs are really great in their own right, but they adhere to different philosophies. The NOVUS focuses on technical performance above all else, but its musicality suffers a bit because of it. Still, it's mighty impressive and hard to fault. The Apostle leans in the other direction and has a very fun and more moving tuning. It is not without its own technical prowess, though it falls short when competing against the NOVUS. Besides both having generally V-shaped tunings, the differences are obvious when compared side by side. The Apostle has a big sub-bass response and more emotive mids, with slightly darker treble, while the NOVUS is better balanced across the frequency response and simply sounds more accurate. While the Apostle is generally more fun and enjoyable for me, the NOVUS would be my choice as an all-rounder, and I would even choose it based purely on rock and instrumental genres. However, the NOVUS's $5,000 price tag is simply not feasible for most audiophiles (including myself), and I think the Apostle offers a better price-to-performance ratio. If money were no object, I would probably choose the NOVUS, but at around a third of the price, the Apostle is still very impressive.
My pick: NOVUS

● Jomo Nautilus ($800) - Here we have a contest of two tribrids, but with quite different driver configurations: 1DD, 2BCD, and 1 planar versus 1DD, 2BA, and 2EST. I did not receive the retail packaging or all stock accessories with the Nautilus, so I'm unable to compare everything. Both sets have thicker cables, and while the Nautilus's is a bit more pliable, the Apostle's cable feels bette built and more premium. I do think the Nautilus has a nicer case, though. As for the build quality of the shells, both are made of metal and feel very sturdy. The Nautilus is smaller, but the Apostle is better contoured and a little more comfortable for me. I also prefer the Apostle's more subtle and nuanced design compared to the Nautilus's extravagant-looking shell. When it comes to tuning, both generally have V-shaped sound signatures, but they sound very different in-ear. The Apostle has a fuller and bolder bass response with more rumble, reverberation, and better sub-bass extension. The Nautilus has decent bass too, though it is lower in quantity and a little more mid-bass oriented. It also has a softer impact, lighter attack, and a slight hollowness to it. In the midrange, the Nautilus emphasizes vocals more, though it can become shouty at higher volumes, and the BCDs add spaciousness and depth to instruments and vocals. The Apostle's midrange is slightly more recessed in comparison, but not significantly. It may lack some of that BCD magic, but the trade-off is a smoother and more emotive vocal response, which better suits my preferences. However, the lower midrange is somewhat dominated by the bass, and I would still prefer vocals to be accentuated a bit more. Interestingly, the set with ESTs actually has a treble response more in line with my tastes. The Apostle rolls off slightly sooner but still retains a crispness and energy that is enjoyable, even for a treble-sensitive listener. The Nautilus is definitely brighter and more energetic, but it also has more air and better extension, which some may prefer. As for the technicalities, the Apostle is superior pretty much across the board. I will give the Nautilus the edge in soundstage, though, thanks to its BCD magic, but that is the only area I can concede. In conclusion, the Nautilus would probably be my choice if I stuck to instrumental genres only, but the Apostle simply dominates everywhere else. It's true the Elysian is more than double the cost, but I think it's well worth the upgrade for bass enthusiasts and those who want a more musical V-shaped tuning without sacrificing technical performance.
My pick: Apostle

● DUNU DaVinci ($300) - Here we have a 2DD, 4BA hybrid versus the Apostle's 1DD, 2BA, 2EST tribrid configuration. When it comes to accessories, I have to give it to the DaVinci. It is actually crazy that a set one-fifth the cost of the Apostle can not only compete with its accessory package but actually win. This is both a testament to DUNU and perhaps a small wake-up call for Elysian. The DaVinci has a nice modular cable, a great zippered case, and a plethora of tip options. The Apostle's cable is nicer, but the case feels a little cheap, and the tip selection is limited. The Apostle, though, does have much better build quality. The aluminum shell is heavier and sturdier but also feels very premium compared to the resin of the DaVinci. Similarly to the Nautilus, the shell of the DaVinci is a little smaller than the Apostle's, but also less contoured, meaning the Apostle again offers a slightly better fit for me. Design-wise, I am a bit partial to the DaVinci's faceplate, but the Apostle has a more understated design that is also very appealing. As for the tunings, both offer a bold bass response but the Apostle is a little more V-shaped and brighter while the DaVinci a bit more U-shaped and more smooth. The Apostle's low end is slightly more sub-bass oriented with a better subwoofer-like rumble and a visceral feel to it. The DaVinci's extra mid-bass presence adds a certain warmth that carries across the entire frequency response which brings a charm of its own. The attack and impact are similar between the two but the Apostle is much more resolving and has a cleaner texture. The DaVinci does have some bleed into the midrange while the Apostle is much better separated and offers a cleaner transition. In the midrange, the Apostle has a bigger scoop in the lower mids, leading to instruments in this area being overshadowed by the strong bass response. The DaVinci has a messier lower midrange due to bass bleed, but it also represents instruments in this area better, in my opinion. Vocals are a little clearer and slightly more forward on the Apostle, with a certain clarity and energy missing on the DaVinci. However, they are more emotionally moving and have more heart and soul on the DaVinci, which I always enjoy. Both sets have a similarly rolled-off treble response, but not without their fair share of sparkle. The Apostle, however, is brighter and more energetic, but it also sounds more complete, considering the balance of the entire tuning. The DaVinci could definitely use a little more air and treble energy, but I enjoy it as is. There is never any sibilance or harshness, which are the quickest ways to ruin a tuning for me. Technically, there is really no contest. The Apostle is the clear winner in every category, though the DaVinci is the more musical and emotive of the two. Some may listen to both sets side by side and say the Apostle might be a clear evolution of what the DaVinci aims for. But for me, while the Apostle is absolutely and unequivocally the better IEM, the DaVinci offers enough differences to make it unique. The combination of mid-bass warmth, lower midrange representation, a flatter pinna gain rise, and a more controlled treble roll-off hits just about every aspect of my target tuning. Don't get me wrong, the Apostle is clearly better, but my choice is about which one I'd rather have in my collection. The DaVinci has fought many IEMs looking to take its crown, but I'm afraid the Apostle is inevitably another foe left defeated.
My pick: DaVinci

● Ziigaat Arete ($250) - Here's another hybrid (1DD, 4BA) to compare against the tribrid configuration of the Apostle. These two actually graph pretty similarly up to about 4 kHz, where they deviate in the treble response. Zingat's accessories are largely the same across most models and are generally disappointing for the price. The Apostle's accessory package is better overall, except perhaps for the case, for those who prefer a zippered one. When it comes to overall design, the Arete has that classic combination of sparkly faceplate and black resin. It's a tried-and-true design but is all too common in the market today. The Apostle is more unique, and its more nuanced aesthetic is my preference between the two. The Arete's resin shell is smaller and lighter, but the Apostle's sturdier metal shell fits me a bit better due to its contoured shape. When it comes to the sound, both have generally V-shaped tunings. Even though the graphs show a very similar bass response, the Apostle most definitely has a bigger and bolder low end. The rumble, reverberation, and extension are all superior on the Apostle. The Arete has a slightly quicker decay and cleaner texture, though it lacks the true subwoofer effect that the Apostle does so well. The midrange of the Arete sounds a little clearer and slightly less recessed than the Apostle. While lower-midrange instruments are a little better represented, the vocals lack emotion and heart, which is another thing the Apostle does very well. However, I find that the Arete's midrange balance fares better with instrumental genres. In the treble, the Arete has more air and better extension, and a little more sparkle. Interestingly, though, snares can sound a bit blunted and cymbals a little splashy. The Apostle's treble has better crispness, more energy, and conveys a certain fun factor missing from the Arete. I also do not find myself missing that little bit of air. In the technicalities, the Apostle is the clear winner in most categories, including soundstage, timbre, note weight, and detail retrieval, but the Arete manages to compete in layering, separation, and imaging. In conclusion, this comparison is a great example of how a graph can't tell the whole story. These two measure pretty similarly, but when performing A/B comparisons, the differences become quite apparent. Honestly, if you sucked out all the emotion and the things that make the Apostle special, the Arete is what you'd be left with. Now that sounds awfully harsh, but don't get me wrong, the Arete is a perfectly fine and capable IEM. It's simply that the Apostle has many special qualities and a certain X factor that doesn't necessarily show up on a graph. The Arete lacks musicality and fails to make me connect to the music in the same way that the Apostle does so effortlessly. People often question why some IEMs are so expensive. Well, for me, it's all about the intangibles—the things that don't show up in measurements and can't fully be explained, but when you hear them for yourself, you understand.
My pick: Apostle

In conclusion:
I acquired my first taste of Elysian's Apostle at CanJam SoCal 2024. While I generally liked what I heard, show impressions should always be taken with a grain of salt, as listening conditions are less than ideal due to the noisy environment and lack of time. Spending an extended period with the Apostle and trying out different sources has been a pleasure and only reinforced my initial positive impressions. This is easily my favorite Elysian to date, and while I enjoyed certain aspects of the Annihilator, Diva, and Pilgrim, none of them really struck me the way the Apostle has. The bass is bold and bountiful but not overemphasized, the midrange is clear and unimpeded while also having a musical and soulful quality, and the treble is just crisp and energetic enough without being harsh, when paired with the right source, of course. On top of the wonderfully executed tuning is the impressive technical performance. When combined, everything the Apostle does well adds up to be more than the sum of its parts. While it can be a serviceable all-rounder for bassheads, it wouldn't be my first choice for rock, alternative, or classical music. I think it is better suited to sub-bass-oriented genres like pop, R&B, EDM, and chillhop. It can be good for some folk and singer-songwriter music as well, but the bass quantity can be a little much at times. I may be in the minority, but I just never connected with any of Elysian's offerings until the Apostle came along. I would absolutely love to own one, and while price is not something I take lightly, this is one IEM that really does justify the cost and could be an endgame for many. If you are looking for a superbly well-done V-shaped tuning with fantastic technicalities and a good price-to-performance ratio, I think you might be hard-pressed to find a better value than this. My hat's off to Elysian for what they have accomplished here, and the Apostle is definitely worthy of the pilgrimage.

ELYSIAN APOSTLE

Let's get started. This is one of my most anticipated loaners of the year. Thank you to @EnigmaFotos and @ElysianAcousticLabs for the opportunity at this loaner set. What a great time to be an audiophile in the IEM segment, due to the existence of gear like the Elysian Apostle. I got the privilege of auditioning the Elysian Pilgrim and the Elysian Pigrim Noir (discussed here as the Noir) last year, and though the OG Pilgrim was an excellent set, it just didn't resonate with me as much as the Noir. That particular IEM hit all the right spots, and was a chill, refined, and fun listen. I was truly sad when I had to let them go back home. So now, the Apostle has shown up for a visit, and the first thing that struck me was just how similar these sound to the overall tonality of the Noir, but take it up several notches. This is the Noir on steroids! This is a far more refined approach than the Noir, with far more rumbly and punchy bass presence. So buckle your seatbelts and prepare for a 100% unbiased impression with heartfelt observations and thoughts. Now on to the fun stuff.



The unboxing experience was quaint but classy. The box has a slip case with the words Apostle embossed in black. Upon removal of the slip, you are greeted with fold out wings, and a classy cover letter by Elysian Acoustics welcoming you to the experience. Under that are the IEMs themselves, the cable carrier, and underneath that is more! The warranty and paperwork case, with Apostle also written on the front, a tip case with various amounts of tips and tip sizes, and the leather carry puck, with a couple sundries. Again, aside from the design, it's a quaint but classy presentation. The cable is a thick, black, 4.4mm Effect Audio ConnX connector cable. It's got moderate pliability, handsome accents, and seemed very secure at the attachment points on the buds themselves. The shells are machined metal, have no irritating points of contact, and fit rather comfortably, despite the shells being on the rather large size. The nozzles suffer from the same issues the Pilgrim's suffered from, which is the nozzles are too short for the contours of the shell, which makes a finicky fit, so tip rolling until you find that excellent seal might take a while, or the need for o-rings. I started with the AZLA Crystals, switched to Spinfit CP100+, and then went back to Crystals, as to squeeze out the last of that treble extension, the Crystals are so good at doing. That's the extent of the unboxing experience, so let's move on to the technical details and sound impressions.

What did I use for my listening sessions for my review??

This is a major IEM, so I used a wide swath of sources to conduct my listening sessions. From tube daps and amps like the Cayin N3 Ultra, the Xduoo XD05T, iBasso Nunchaku, and Little Bear B4-X, to the Cayin Ru6 r2r dongle, iBasso DCE, FiiO JM21, Dethonray Clarinet, iBasso DX170, Sony NW-ZX100, A25, A55, and Hiby R3 II. So one of the broadest use cases I've ever utilized for a review.

BASS/MIDRANGE/TREBLE :

The Elysian Apostle, in the marketing claims, was said to be the Elysian Annihilator Jr. I wouldn't know exactly, since even though I am signed up for the Annihilator 2023 tour, it hasn't landed on my porch as of yet, but I can confidently say that I feel the Apostle is the Elysian Pilgrim Noir Sr. They share DNA in their sonic presentations. Where they diverge is in the top and and low end. The low end of the Noir is impactful, but linear, with a restrained sub bass, where the Apostle comes at you with all guns blazing with an energetic, punchy, rumbly, and yet note resolving and incisiveness that you rarely find in other IEMs. You will get rumble and punch, with energy and impact, or you get a linear bass with note resolution, but rarely BOTH. This is why the bass of the Apostle is my favorite trait. Usually I'm picking the treble over the bass or mids, as a true treble connoisseur. Not here. Not now. I'm taking that energy, impact and rumble. It's fun. It's toe tapping. It's strong, but it's never overbearing or overpowering (unless called upon to do so), so it's a very heavy handed mid bass (in a good way), quaky sub bass (when called upon), and very energetic! To sum up the bass of the Apostle, I'd say it walks a balance of bass head impact, but linear bass connoisseur resolve. Again. this is quite rare, where a bass can walk that line between the two traits, but in this case, the Apostle delivers in this way. The bass presentation is truly special.

The midrange is warm, transparent, fluid, immersive, incisive, and spacious. Where's the BCD? There isn't any? What?! With the way the midrange is presented, with those spatial cues, instrument separation, imaging, and stage very full, immersive, and transparent. Now there is a bit of warmth bestowed by the mid bass into the midrange, especially the lower mids, which provides warmth, note weight, and a natural timbre, and fluidity. Now it also can mask some finer details, even with the transparent quality of the midrange as a whole. This is apparent when looking for faint whispers, laughs, voices, or instrument placement in the midrange mix. Toto - Africa, Robert Glasper - Enoch's Meditation, China Drum - Barrier, Cinder - Please God, or in the case of the Rolling Stones - Beast Of Burden, there's a strum of an acoustic guitar buried in the mix, that's faint but audible, and it is in fact audible, but fainter in the play back due to the compromise detail retrieval from the added mid bass presence within the midrange. Now, this isn't to say this is a bad thing, it just limits the sheer amount of details that are presented within the spacious stage of the midrange. One of the positives of this are male and female voices are emotive, warm, immersive, and engaging. Voices are beautifully spaced, placed, and performed, with a weight and tone that are natural and expressive. So there are trade offs, but I think it's worth it for that natural timbre and effortless musicality. With the upper mids, there is no shout, no crispiness, no sibilance, and no peaks. This is a mature, refined, with a elegant fluidity to the upper midrange that compliments the lower mids, the center midrange, and all the way into the treble with a effortless tonality.

Speaking of effortless and natural, that could very easily be the main descriptors of the treble of the Apostle. Driven by dual EST's, it's textured, reserved, natural, crisp, and incisive. Actually, the EST's are much more reserved that I was expecting, due to the marketing as an Annihilator Jr. I was expecting more than just that, marketing lingo, because I can't imagine a treble that has been described as the most textured airy, and extended of any IEM in the world, would be anywhere near the Apostle's treble, because I would not describe the Apostle treble in those terms. It's crisp, but it's not the most airy. It's not the most shimmery. The ISN EBC80 has more airy harmonics, as does the Thieausio Oracle MK III, and both are dual EST, like the Apostle, with the latter delivering a more natural texture with a crisp, refined, and controlled extension that I would say is more safe than strident. More reserved than shimmery. Now I did discover, quite by accident, that the Apostle synergizes in a unique way with the Hiby R3 II. Usually I use the R3 II tethered to a DAC or amp, but this time, while waiting for a DAP to charge, I decided to plug the Apostle thru the R3 II via 4.4mm, and synergy sisters were created quite surprisingly. The Apostle gave off more air and extension when using this DAP, and not only that, but the upper mids were a bit cleaner (less warm), and the bass became a touch more linear in the mid bass, so that I got a slightly brighter tone, though still very full and refined with that immersive stage left intact. Has I discovered this earlier, I would have spent more time with this combination, as it really checks all my personal preference boxes. If you've had the opportunity to hear the Elysian Noir, then you get in the ballpark of what to expect treble extension wise, just with even more resolution, crispness, and refinement, with similar extension, air, and shimmer, but less laid back, and with EST tonality instead of BA's.



Comparisons :



Lime Ears Maris ($2,799) : I'm incredibly fortunate to have the Lime Ears Maris in my possession at the same time as the Apostle. Though the Maris retails for $1,000 more than the Apostle, I don't believe the Maris, sonically, supersedes the Apostle, but it does out finesse the Apostle in some attributes, while falling short in other ways. Just like the Noir, the bass of the Maris is a league lower than the Apostle. It lags behind in energy, impact, and sub bass rumble. The only facet of the bass where the two would be considered equals is in the note resolution and incisiveness, where the Maris acquits itself rather nicely against the Apostle. The midrange of the Maris, while being less warm, brings the technicalities, has no warm veil, and so detail retrieval is superior, while delivering a cavernous midrange stage that's more dimensional in width, height, and depth. BCD in the house!! I think the midrange tonality is much more natural and fluid with the Apostle, while being a touch more incisive, and the vocals are more emotive and textured, with the Maris having a thinner note weight and vocal presentation. The treble of the Apostle is more textured and natural. I wouldn't call it more refined, since the Maris never gets strident, and is actually tuned in that safe, almost nu-meta style as the Apostle, but it's a little airier, but with slightly less control, and slightly less musical than the Apostle. Slightly less fun. Advantage : Apostle.

Penon Archangel ($800.00) : Costing less than half the price of the Apostle, and $2,000 less than the Maris, the Archangel is easily my favorite acquisition in 2025. Sonically, it's like a cross between the Apostle and the other Lime Ears IEM that I have in my possession, the Lime Ears Incognita. Archangel has 2 DD + 2 BCD + 2 BA, and it's bass is tuned very similar to the Apostle. I'd say the only difference between the two is that the note resolution is slightly greater with the Apostle, while the mid bass extends and punches a bit further into the lower mids than the Apostle, while the Apostle delivers slightly deeper sub bass rumble. The midrange is warmer and lusher with the Archangel, and has less transparency, fluidity, and refinement. It's also a step behind in detail retrieval and imaging, though the soundstage dimensionality is very similar to the Apostle. I'd say the Apostle is cleaner and fuller, while the Archangel is more immersive and orbital. Note weight is similar. Archangel's upper mids and treble is far more incisive and airy. To the point where you might pick up some sibilance on tracks that have that baked in, whereas the Apostle never gives up the sibilance ghost. Timbre is more natural with the Apostle, but harmonics extend far higher with the Archangel, with top end shimmer and crispness superseding the Apostle, but this comes at the cost of BA sheen and less control and natural texture. So if you're a treble head, you'd lean towards the Archangel, and if you're into more emotiveness and refinement in the midrange as a whole, while valuing safer tuned upper mids and treble, then the Apostle is the pick. Bass is a pick 'em, with the Apostle supplying a more balanced approach to the bass presentation, and the Archangel a more heavy handed mid bass approach. Advantage: Apostle.



CONCLUSION :

The Elysian Apostle surprised me. Both good and indifferent. Good, in that I was really expecting a refined and immersive listen, and I got just that. Good in that the bass was so hard hitting and rumbly, but defined and incisive, and that was another very good surprise, but also indifferent in that I was hoping for, or expecting well extended, airy, and shimmery treble like the Annihilator (Jr), but instead I got a nu-meta, safe, natural, and controlled treble. I still enjoyed it. Especially thru the Hiby R3 II and the Nunchaku. It's easily the best IEM I've ever heard from a natural, refined, bassy and spacious POV. It's most definitely an able and adept all-arounder, which can deliver reggae, rock, or jazz with equal aplomb as it does extreme metal, prog, or hip hop. If you have $2,000 to spend, and you're looking for a fluid, musical, and natural, yet bassy all-arounder, then the Elysian Apostle should be at the very top of your list, and the tip of your tongue. If you own the Pilgrim Noir, and you're looking for a direct upgrade, then the Apostle is exactly this, and it'll cost you double what you paid for the Noir, but IT'S WORTH IT. The Apostle is sexy, sultry, sinuous, and steady. Refined, with no hair out of place. Simply put, the Belle of the ball.

RECOMMENDATION LEVEL : TOTL BOSS LEVEL ALL-AROUNDER - HIGH 9/10.

Thank you so much for reading and remember to be water with your audio luv! When you do...AUDITORY ZEN UNLOCKED!

This is my first time writing a review on headfi, so I'm going to be short and concise.
Disclaimer: I am an Elysian fanboy. I owned Anni 2021, X, and Diva. I can be biased.

Without further ado, here's the measurement on B&K 5128. (Big thanks to the hangout crew for measuring my unit) (yeah, channel balancing can be improved lol)


Apostle sports a neutral tuning with a noticeable lift in the sub-bass and lower midrange with good air extension. There is a slight dip around 5-6k which I understood from Mr.Lee that was intentional.
This type of tuning gravitates a bit from the Elysian House sound towards a more JM1 tilt signature. However, Apostle still retains that vocal forwardness which is beloved by the community. On the other hand, I do think marketing it as an Annihilator Junior is misleading. To my ears, Apostle sounds more like Pilgrim ultra than Annihilator.

Bass: Apostle used the same LSR tech DD driver used on Pilgrim. It is fast, rumblely, and satisfying. In fact, it is arguably the best bass profile for rap in my opinion. However, if you are an instrument or acoustic enthusiast, the bass on Apostle may be overpowering in certain cases. For pop genre in general, I would say Apostle is well within the range of most people.

Midrange: This may be the most controversial part of the set. Normally with Elysian's style of tuning, you have a bump in the 1-2k region, with good lower treble maintain and finally dropping around 6-7k. Apostle is not that. As a result, it is noticeably darker than say Diva. The 1-2k bump usually helps to bring the vocals forward, and it did in this case. However, Apostle starts to decade at a fast rate past 4k, so it feels like you are getting a lot of 1-3k pinna gain, but not enough lower treble for some.

Treble/Air: The treble as a whole is ultra smooth and balanced relative to the rest. It is not exciting nor boring but sits between the two. The use of dual est is good in this case. However, crin and I do think a BA can achieve a similar response. Of course, we all know Mr.Lee likes using his est and he is a wizard at that, so it makes sense to have it on a premium product.

Comparison: The biggest elephant in the room I want to address is whether Apostle is the successor for Diva (since Diva is now discontinued). The short answer is, no.

This is the most confusing part I found. Just by inspecting measurements, Diva and Apostle are not that different at all. However, in actually listening, I found Diva to be much brighter. I can argue that Diva maintains more in the upper midrange, however, Apostle does have more extension in the higher frequency.
There are two theories. One, Apostle is more filled in the lower midrange and midbass, so the contrast between fundamental frequency and treble is weaker. Two, it depends on different hrtfs. I demoed my Apostle to quite a few friends, and the response I received was varied. Some think Apostle is around the same brightness as Diva. Some responded that Apostle is much much darker. I guess this is the part you just have to try for yourself if you have the chance to demo it. But to conclude, it is NOT a replacement for Diva.

Conclusion: Apostle is a well tuned iem. It is, I believe, the most neutral set Mr.Lee has made so far. It is, however, very different from the other Elysian products and I highly recommend demoing it before purchase.

​

Oh look, another audiophile who went to Can Jam and fell in love with yet another high-end IEM. Shocking. But here's the thing - after spending two days at Can Jam SoCal bouncing between talking to people and serious listening sessions, I kept finding myself drawn back to the Elysian Apostle like some sort of hi-fi moth to a flame.​

I know what you're thinking: "Great, another gushing review about expensive ear jewelry." But stick with me here. While I did indeed drink the Kool-Aid (or perhaps the audiophile-grade mineral water), I promise to break down exactly why the Apostle's approach to neutrality and simplicity isn't just marketing speak, but something that genuinely elevates how I experience my music.​

The word "legend" carries weight in my book, audiophile world - a term I reserve for those rare pieces that truly transcend the ordinary. So often the hobby is plagued with iems coming out every few weeks hoping people will buy them. This iem was actually delayed almost two months to make sure it was correct and right. This is a sign of care, of quality control, as you can only release a product once. I always appreciate companies with the backbone to delay products despite the sadness of not being able to experience it right away.

Every once in a while you get an iem, that measures well, is well made, and actually sounds good in ear. This Elysian Apostle is that iem. The Apostle has earned this distinction, presenting itself as more than just another flagship IEM. It's a creation that promises to leave an indelible mark on the industry for years to come.

Technicalities

Audiophiles often talk about the technical performance of an iem. Very rarely does an iem impress me on that standpoint. Technicalies are interesting and a weird way to describe iems in general, but they help us understand them in a wide variety realm of distinctly different tuning. But this tuning is fantastic to my ears. The levels of details really shine in this iem to a level that is very different and unique in the Space.

Reflecting on the parade of IEMs that crossed my path in the past year and it’s a lot with loans, purchases, demos, and tours, many impressed, and some even excelled. But the Apostle, emerging in the early days of 2025, stands apart from the rest. It doesn't merely join the ranks of exceptional audio gear - it redefines them. Among the countless IEMs I've experienced, it has secured its place in my personal top three, an achievement that speaks volumes in this ever-evolving landscape. To which nothing from 2024 has done that, one being from 2022 and the other from 2023.

There's something magnetic about its presentation that keeps drawing me back. It's simple enough to point out flaws in mediocre IEMs, to highlight where they fall short. But when confronted with something truly innovative, something that pushes boundaries and challenges our expectations - that's when the real challenge of audio criticism begins.



Annilator 2023 vs. Apostle Comparison:

Bass response: The bass response is hard to define as the Apostle feels slammer, darker, but the Annihilator measures better for bass. I feel the Anniliator is slightly boomie and bloated, but overall not bad. The Apostle is a little more mid focused with ample sub bass to satisfy most bass heads. They are tuned differently.



Vocal presentation:

• Apostle: Brighter, more spacious forward vocals with a special quality that makes them stand out in a sense, but also provides more space and naturalness.
• Annilator: Sparklie vocals, more engaging, but with excellent vocal clarity and natural tone

The Anni 2023 edition brings some refinements:

• Vocals have more immediate "pop" and presence
• Overall sound signature becomes more engaged
• Achieves a more fun presentation

Neither can be definitively called "better" - they represent different philosophies in sound tuning. Each excels in its own way:

Design aesthetics:

• Apostle takes the lead with its more refined industrial design
• Anni 2023 maintains its own distinctive appeal and remains a special piece with more energy in the bass and upper treble.

Both are flagship-level pieces that excel in different ways. The choice between them comes down to personal preference in sound signature and presentation style rather than absolute technical capability. I feel a lot of the neutral lovers will call Apostle the better iem, and there are elements from both that I feel make both acceptable to own and love.

Diva 2023 vs Apostle

With the Diva 2023 closely mirroring the original Diva in frequency response, the Apostle effectively steps in as its spiritual successor as third in a series right around this sub 2000 dollar price. Unfortunately both Divas have been discontinued. While there's a certain nostalgia in seeing the beloved Diva name take a back seat - and I share in that sentiment with other enthusiasts - this transition brings significant improvements.

Technical Improvements:

• Bass response: The Apostle delivers cleaner, more impactful bass having more balanced sub and mid bass performance.
• Overall driver performance: Notable upgrade in technical capability
• Treble presentation: More refined and detailed
• Overall clarity: Markedly improved across the frequency range

Design Philosophy:

• Diva: Offered versatility with three interchangeable bass dial settings for different sound signatures
• Apostle: Focuses on perfecting a single, carefully crafted tuning

While some might miss the Diva's adaptability, the Apostle's singular tuning achieves a level of refinement that surpasses what was possible with the multiple tuning approach. It carries forward the Diva's DNA while elevating the technical performance across the board. It carries that vocal specialiness of the Diva with much improved technical performance.

However, Diva enthusiasts who relied on specific base dial configurations might find the transition challenging, as the Apostle presents a different, albeit more refined, listening experience. It's not so much a replacement as it is an evolution - one that prioritizes absolute performance over customization.

While the Apostle represents a clear evolution in refinement across the board, I deeply understand the emotional connection many have with the Diva. That special synergy between listener and IEM isn't always about technical superiority—sometimes it's about a magical moment or a particular signature that just clicks.

For our dedicated Diva enthusiasts, I'd gently suggest giving the Apostle a fair audition, whether through a tour or demo. It builds on the Diva's legacy while pushing boundaries further. However, I completely understand if the Diva holds an irreplaceable spot in your collection. Great IEMs are like old friends—even when newer ones come along, the original connection remains special.

The great thing about IEMs is that unlike romantic partners, you can have a whole collection and they won't complain about your "audio polygamy." They're perfectly content sharing drawer space - no passive-aggressive notes about who's taking up too much room. The only drama you'll get is when you accidentally put the right ear tip on the left side, and even then, they're pretty forgiving.

Perhaps someday we'll see a reimagined Diva that captures that original magic while incorporating what Elysian has learned. Until then, whether you're team Diva or ready to embrace the Apostle, there's room for appreciation of both.


Vs Monarch MK2
Value and Build Quality: While the Monarch MK2 remains an excellent value proposition at roughly half the price of the Apostle, the build quality gap is significant. The Apostle's construction represents a major leap forward from the Monarch MK2's now-aging design.

Technical Performance and Tuning:

• Upper Mids:
  • Monarch MK2: Presents a cleaner, more straightforward approach. This feels a little more mainstream and attractive to many..
  • Apostle: Features the distinctive "Diva-like" effect that adds dimensionality and detail retrieval, though some might prefer the Monarch's more traditional presentation as it is very close to the JM-1. The Apostle has that special effect and magic that is better to me.

Sound Characteristics:

• Monarch MK2: Maintains its reputation for excellent technical performance at its price point
• Apostle: Pushes technical boundaries further, offering flagship-tier performance that justifies its premium positioning

A Note to ThieAudio: The Monarch MK2's tuning remains beloved by many enthusiasts (myself included), and there's a strong case for revisiting this successful formula. Rather than exploring entirely new tuning directions, perhaps considering a premium version of the MK2 - with enhanced build quality and technical performance while maintaining its core sound signature - would be welcome in the market.

The Apostle's Position: It's fascinating to see how the Apostle bridges multiple roles - it carries elements of the Diva's legacy, shares some DNA with the Annilator 2023, yet forges its own distinct identity. This versatility, combined with its technical excellence, suggests we're witnessing the birth of a new classic in the high-end IEM space.

Drivers

I think the drivers are very nice from my perspective. I’m not 100% sold on how much drivers matter and try not to preach them over anything, but I do feel that Elysian has used very nice drivers in this case. I do feel they play a factor and are interesting. But my big thing here is that I don’t personally tune iems, design iems, and understand exactly what is happening in these products. Here is some information on the drivers.
5 Drivers Tribrid Design

• 1 × Custom 9.2mm LSR DD for Lows
• 1 × Knowles ED-30000 BA for Low-Mids
• 1 × Sonion 2300 BA for Mid-Highs
• 2 × New Generation Sonion ESTs for Highs

Here is some more information from the press release about the drivers.
“LOWS: ANNIHILATOR 2023 Foster Dynamic Driver to APOSTLE LSR Dynamic Driver

Appearance:

The Shell
The shell design is exceptional, echoing the architectural elegance of Dita's Mecha Shell while taking it a step further. The precision-crafted metal housing combines durability with refined engineering, making both a functional and aesthetic statement. The shell has nice contours and curves with a beautiful appearance.
The sophisticated grey finish, complemented by black nozzles, creates a cohesive look with the cable. It's an exercise in intentional minimalism - clean, elegant, and modern. Every element feels purposeful, turning a functional IEM into a piece of technological art. The nozzles being black is a huge bonus for me, but you don’t really get to enjoy them on a daily basis as they are covered mostly by the tips.
The metallic construction balances durability with sophistication, where practical needs meet visual refinement. Despite its premium build, it remains lightweight and comfortable, with an ergonomic fit that works well for most ears.




The Cable
The cable demonstrates impressive craftsmanship, with a texture that feels refined. The marketing compares it to a warrior's sword, which isn't far from the truth. It's rare to find an IEM where the cable and design complement each other so well. Both are light and purposeful, reminiscent of a well-balanced blade.
As someone who appreciates swords, I can see the engineering nuance here. Like a good sword, the cable balances lightness and durability. It's both delicate and strong—a subtle engineering achievement. The best swords are durable, light as a feather, and have a delicate grippy handle. This strangely describes how the cable is in my use of it.
Pentaconn connector compatibility has been challenging with Elysian IEMs, which makes this cable a welcome find. Its texture is soft, and it lays flat easily. There's a slight microphonic noise when it rubs up against other object, but it's barely noticeable during music playback and seems to diminish after a few days of use. The cable's low profile and ease of management are particularly appealing.
I'd definitely consider purchasing a second cable if the opportunity arises.





Drivability and source gear

The IEM demonstrates notable source dependency, with performance nuances that emerge across different digital audio sources. In my evaluation, the most compelling sound signatures were achieved with the Quolos MUB1 and Cayin N6iii DAP, though individual experiences may vary significantly.
The device exhibits subtle scaling characteristics, with marginal but perceptible sound quality improvements across different DACs. Notably, it maintains an impressively low driving requirement—considerably more efficient compared to many IEMs in its category.
For optimal performance, I recommend a 4.4mm balanced connection. However, there's no necessity to invest heavily; a quality dongle or DAP in the $50 range will provide excellent results.




Tips:
The IEM includes Divinius Velvet tips, which are exceptional. These tips offer a unique combination of comfort and sound isolation that sets them apart from standard options.
While tip preference is highly personal, the Velvets provide a well-designed solution that enhances the listening experience. Their soft yet resilient material conforms well to the ear canal, creating an impressive seal.
For some users, the specific tip might be a point of contention. Note, these are my favorite tips that I personally buy and use. However, for listeners who appreciate their qualities, these tips represent a thoughtful addition to the package. They demonstrate the manufacturer's attention to detail beyond typical accessory inclusions.
Potential buyers should take the time to evaluate these tips, as they could significantly impact overall enjoyment of the IEM.

The Case

The Apostle comes with a leather puck case featuring the Elysian symbol. The case immediately reminded me of similar designs from Aful Performer 8 and 64 Audio, sporting a premium look and feel.
Typically, I'm a minimalist who prefers small plastic boxes that allow me to see my IEMs directly. However, this leather case is an exception. It feels well-made, durable, and substantial in hand. Compared to cases from the Annihilator or the recent Pilgrim models, I find this one superior in texture, build quality and durability.
The case is well-made, but at the end of the day, it's just a case. While nicely constructed and aesthetically pleasing, it doesn't impact the listening experience. It's a thoughtful addition that hints at the overall product design, but not something to get overly excited about.
The case represents a small but noteworthy element of the IEM's package, adding a touch of sophistication to the product. For those who value presentation and protection, it's a definite plus.







Overall Sound

The sound signature of this set features a pronounced V-shape profile—decisively so, rather than leaning neutral or L-shaped—resulting in a dynamic and engaging presentation. While some tracks may exhibit heightened energy, this characteristic contributes to their entertainment value.
The bass response is both refined and gratifying, delivering substantial presence without overwhelming the mix. Its progressive elevation is particularly well-executed, avoiding jarring transitions that might otherwise detract from the listening experience. The cohesiveness is remarkable, and the low-end presentation demonstrates both richness and precision that's uncommonly found at this price point.
In terms of treble, the airiness is competent, though not extraordinary. It maintains clarity while remaining pleasant and unobtrusive. The bass impact and slam are particularly noteworthy, delivering a deeply satisfying low-end experience that fulfills all expectations.
The upper midrange exhibits some emphasis and occasional exuberance, yet manages to maintain an overall cohesive presentation that remains thoroughly enjoyable without becoming excessive.

Comparison


Annilator 2023 vs. Apostle Comparison:



Bass response: The Anniliator delivers more prominent bass with greater impact, while the Apostle takes a more measured approach. Neither is better - they simply offer different presentations.

Vocal presentation:

• Apostle: More Spacious but forward vocals with a special quality that makes them stand out in a sense, but also provides more space and naturalness. A beautiful darkness to the sound, with great richness.
• Annilator: Excellent vocal clarity and natural tone, but more energetic and Trebblie rather than rich and dark.

The Anni 2023 edition brings some refinements:

• Vocals have more immediate "pop" and presence
• Overall sound signature becomes more Excited
• Achieves a more fun, more engaging presentation

Neither can be definitively called "better" - they represent different philosophies in sound tuning. Each excels in its own way:

Design aesthetics:

• Apostle takes the lead with its more refined industrial design
• Anni 2023 maintains its own distinctive appeal and remains a special piece with more energy in the bass and upper treble.

Both are flagship-level pieces that excel in different ways. The choice between them comes down to personal preference in sound signature and presentation style rather than absolute technical capability. I feel a lot of the neutral lovers will call Apostle the better iem, and there are elements from both that I feel make both acceptable to own and love.

Rather than exploring entirely new tuning directions, perhaps considering a premium version of the MK2 - with enhanced build quality and technical performance while maintaining its core sound signature - would be welcome in the market.

The typical 3k peak feels a little flattened out on the Apostle which is unfortunate for many who love it, but it allows the iem to be played at higher volumes and helps it scale exceptionally well. I do find both tunings to be very nice and neutral.

The Apostle's Position: It's fascinating to see how the Apostle bridges multiple roles - it carries elements of the Diva's legacy, shares some DNA with the Annilator 2023, yet forges its own distinct identity. This versatility, combined with its technical excellence, suggests we're witnessing the birth of a new classic in the high-end IEM space.



Gaming

For those brave souls willing to venture into gaming with a premium $1800 IEM, you're in for quite a treat. The balanced tuning and relaxed presentation create an unexpectedly excellent gaming companion. While some might raise an eyebrow at using such a refined piece of audio equipment for gaming (and perhaps rightfully so), the experience proves remarkably compelling.
The dynamic bass response adds genuine weight and impact to explosions and environmental effects, while the airy treble ensures you'll catch subtle audio cues like footsteps and reloads with pristine clarity. The soundstage, is ultrawide, strikes an ideal balance—intimate enough for precise positioning yet spacious enough to prevent congestion during intense moments.
What truly shines here is the detail retrieval during chaotic encounters. Whether you're in the midst of a frantic firefight or navigating a complex battle royale endgame, the imaging capabilities are simply outstanding. The IEM presents both vertical and horizontal positioning with impressive accuracy, creating a three-dimensional sound space that gives you a genuine tactical advantage. Every rustle, footstep, and directional audio cue is rendered with remarkable precision.
The cohesive presentation ensures that even during the most hectic gaming moments, you'll maintain a clear sense of spatial awareness. Despite its primary purpose as a music-focused IEM, it proves surprisingly adept at gaming tasks, handling everything from atmospheric exploration to competitive multiplayer with aplomb. While investing in a $1800 IEM primarily for gaming might raise some eyebrows, those who already own these will find themselves with a surprisingly capable gaming companion that doesn't compromise on performance or enjoyment.
The end result is an IEM that, while perhaps overqualified for gaming duties, delivers an immersive and precise gaming experience that might just spoil you for lesser gaming headsets. It's a reminder that great audio is great audio, regardless of the source material.










Graph:

For the graph please note a few things. First this is sensitive to impedance in the best way possible. An impedance adapter adds a lot more fun bass to this iem, and I really enjoy it.

Secondly I was asked to regraph it with a shallow fit, and it does change the amount of a dip at 6k.
Sound - Final Impressions

The IEM delivers a refined, neutral presentation with well-balanced mids, bass, and treble response. Its technical performance demonstrates careful tuning and attention to detail across the frequency spectrum.
However, personal preference plays a crucial role in IEM selection. While I find this signature excellent for its clarity and balance, listeners seeking specific characteristics may have different reactions. Those who prefer enhanced bass impact, elevated upper mids for vocal presence, or more dramatic sound coloration might want to explore other options.
The IEM presents a measured, slightly dark signature that prioritizes refinement over dramatic coloration. While this mature tuning approach might feel safe to some listeners, it delivers a fatigue-free experience that maintains excellent technical performance and coherence throughout extended sessions.
What's particularly interesting is how the signature scales with volume. At higher listening levels, the IEM reveals more of its dynamic capability and engagement while maintaining composure - never becoming harsh or compressed. This behavior suggests careful tuning considerations for listeners who prefer to push their volume for additional engagement, though the presentation remains clean and controlled even at modest levels.
The signature prioritizes accuracy and cleanliness over dramatic emphasis in any particular range. This approach, while technically accomplished, may not align with everyone's listening preferences. For instance, bass enthusiasts might find the low-end too controlled, while others might wish for more sparkle in the treble region.
It's worth emphasizing that these observations reflect sound signature preferences rather than technical performance. The IEM executes its intended tuning with precision, but whether this tuning matches your personal taste is entirely subjective.


Gifting/who is it for: The Apostle presents itself as a refined, high-end audio product with a distinctly sophisticated industrial design. The cohesive design language spans all elements - from the understated grey aesthetics of the case to the premium shell construction, thoughtfully designed cable, and even the included ear tips. It's rare to find an IEM where every component hits the mark, but the Apostle achieves this elusive Four out of four perfect score in its physical presentation. While I don’t always score for these factors, I do always think about them.
In contrast to some recent releases in 2025, like Moondrop's anime-inspired aesthetics, the Apostle takes a more grounded approach. Its design language evokes high-end armor or precision machinery - robust yet elegant. The build quality inspires confidence; this isn't a delicate piece that needs gentle handling, but rather a premium tool built to last.
The rugged yet refined character makes it an exceptional gift choice, particularly for someone who appreciates technical excellence and clean industrial design. It's the kind of product that makes an impression from the moment you open the box, yet backs up its visual appeal with genuine acoustic performance. The Apostle would be particularly well-suited for:

• Audio enthusiasts who appreciate understated luxury
• Professionals seeking a premium listening experience without flashy aesthetics
• Anyone who values durability alongside performance
• Those who appreciate the intersection of industrial design and audio engineering

The combination of its robust construction, sophisticated appearance, and engaging sound signature makes it an impressive gift - though naturally, at this price point, it's best reserved for those special occasions or recipients who would truly appreciate its qualities.



Pairing: I tested this IEM across several sources: the iBasso Elite for mobile use, iBasso DC07 dongle DAC with my laptop, and JDS Labs Element 4. A brief test with the Apple dongle confirmed its easy-driving nature. Unlike some planar IEMs or over-ear headphones that can be power-hungry, this IEM performed consistently well across all sources without any power requirements concerns.

The Bottom Line​

This set has thoroughly impressed me, and I believe many others will like it as well. It feels like a natural evolution of the Elysian Diva, and while in many ways it surpasses the Annihilator, I still hold a special place in my heart for the Annihilator's unique magic. At this level of the hobby, it becomes tricky to definitively say what makes one IEM "better" than another. Comfort, design, and price all play crucial roles, and the Apostle excels in these areas while delivering a sonic signature that's remarkably close to its predecessors. Some folks will naturally prefer the Diva or Annihilator, but the Apostle brings its own unique sound signature to the table that's worth experiencing.
I've spent countless hours searching for that perfect sound, and while I don't believe it truly exists, this comes remarkably close to that endgame territory for both enthusiasts and casual listeners alike. It sets a new benchmark that's genuinely special. If I could give this set 6 stars today in my review, I would. On my sonic rating scale, I'm giving it a perfect 10 - something I've never done before. This set has been occupying my thoughts for months, and for good reason, it’s impressive.
If you've never ventured into this price tier for IEMs, maybe dip your toes in shallower waters first. But for the seasoned audiophile already swimming in these expensive depths? This is the catch of the day, the real McCoy and the one to beat all together.
I've gone through more high-end IEMs than I care to count - Chronicle, Annihilator 2023, Fat Frequency GM, Cadenza 12, AME Mousa, Fir Audio Radon 6, Symphonium Crimson, AME Raven, Fei Wan, Campfire Astolith... takes breath. Even with more expensive IEMs in my collection, this one stands out like a diamond. Sure, it might not be everyone's cup of tea, but in terms of build quality and sonic performance? chef's kiss It's the real deal. And yes, I'm totally flexing my IEM collection right now, but someone had to say it.
