Gizaudio x Binary Chopin VS Kiwi Ears Aether

Initial skepticism about yet another reviewer collab IEM quickly evaporates, as the Gizaudio x Binary Chopin is declared a standout, potentially the best collab IEM in years and even an all-time favorite. For a $200 hybrid IEM from a relatively unknown company, it delivers a performance that is really, really good, making it an exceptionally exciting and competitive offering in its price bracket.

Physically, the Chopin is a bit of a mixed bag with an awkward, truncated teardrop shape, but it scores points for its compact overall size. The main fit consideration is the wide nozzle, which requires a secure ear tip for stability since the entire fit depends on the ear tip coupling with the canal. The included cable is praised for being simple, lightweight, and highly functional with a secure chin slider.

Where the Chopan truly shines is its sound. While its graph looks similar to the lackluster Truthear Nova, the Chopan's significant deviation with meatier bass provides a welcome sense of heft and body, making the entire presentation more enjoyable. The mid-range is clean and vocals are fantastic, coming across crisp and well-isolated. However, the star of the show is the outstanding treble, described as sharp, incisive, and possessing a great sense of weight that outperforms not just its competitors but even more expensive sets. It is declared superior to legendary IEMs like the Moondrop Dusk and the 7Hz Timeless, making it a full five-star product and an easy recommendation.

The Gizaudio x Binary Chopin IEM is an absolute standout, delivering a fantastically unique and immersive sound signature that is heavily focused on vocals. The presentation is spectacularly detailed, making any vocal track, from opera to pop, slam you in the eyeballs in the best way possible. The soundstage is its most intriguing feature; it doesn't sound wide or narrow but instead creates a phantasm-like effect where the music seems to wrap around and even behind your head, a phenomenally cool and different experience.

This is achieved through a hybrid driver setup of a single 8mm dynamic driver for a natural and impactful low end, plus three balanced armatures handling the mids and highs. The package is exceptionally well-presented with a clean box and a professional-looking case. It also comes bundled with the Divinus Velvet tips, which are so smooth they are considered the best pairing for this IEM and are almost mandatory for the intended experience.

Priced at $200, the Chopin is 100% worth it. The build quality extends to its cable and the smallest two-pin connectors ever seen, and the overall tuning is simply fantastic. It’s a refreshingly different IEM that avoids any painful treble or recessed mid-range, making it an easy, highly recommended pick for anyone looking for something special that excels with vocal-centric music.

The Gizaudio x Binary Chopin presents a unique value, particularly for those who typically prefer speakers or over-ear headphones. Its greatest strength is its extreme comfort and easy fit, making it ideal for long gaming or music sessions without the pressure buildup common with other IEMs. Sonically, it boasts a very good quantity of bass and exceptional vocals that really pop in the mix.

However, the Chopin is not without its weaknesses. The quality of the bass is not world-class, and it can lack some air and sparkle in the highs. The most significant complaint is in the technicals of instruments, which can sometimes sound a bit muffled, unresolving, and odd in their tonality and timbre compared to the standout vocals.

When compared to the TruthEar Nova, the Chopin is found to be livelier and more musical, with warmer, richer lows, while the Nova is drier and more clinical with slightly better highs. Both are considered technical benchmarks at their respective price points. The Symphonium Meteor, meanwhile, is deemed overpriced and its bass is noted as being too overpowering, making the music sound off despite its small, comfortable shell.

The Gizaudio x Binary Chopin is positioned as a more authoritative and engaging take on the familiar Harman target. It features a pronounced sub-bass that fills in the typical scoop without overdoing it, providing more slam and weight than predecessors like the Nova or Hexa. This gives the low end more authority, preventing it from sounding anemic, though it doesn't reach the subwoofer-like physicality of sets like the EA1000. The mid-range remains very clear, uncolored, and well-separated, benefiting from the extra mid-bass to sound fuller than the Nova while maintaining a correct tonal balance with no bias toward male or female vocals.

The upper mids and treble are where the Chopin really differentiates itself, coming across as a more engaging and lively version of the Nova. A boost in the 5k and 10k regions adds excitement and liveliness, creating a more open and airy stage. This makes it reminiscent of the Simgot EA1000 but much smoother overall. When compared to other sets, it's a clear upgrade over the Nova and bests competitors like the Performer 5 and EM6L with its better resolution and treble extension without low-end sacrifice. It's also a smoother, more weighted alternative to the Heyday and a more affordable option that delivers about 85% of the performance of the Moondrop Variations.

Ultimately, the Chopin is a smoother all-rounder that makes the standard Harman target less boring. It's a highly competitive set that sounds cleaner than the Kiwi Ears Hype 2 with a less pronounced bass that better highlights the mid-range, though the Hype 2 retains an advantage in bass texture for genres like EDM and hip-hop. The choice between them becomes library-dependent, but the Chopin stands out as a very well-tuned and compelling option in its price range.

Kiwi Ears Aether arrives as a ~$170 planar with a classy, comfortable shell that seals well despite its larger size and visible venting. The accessories are familiar—typical Kiwi Ears case, okay tip selection—while the cable feels like a real upgrade: soft, pliable, and tidy with a solid 3.5 mm termination. Fit can be great, but smaller ears should note the chunkier housing.

Sonically, Aether leans neutral-bright with a clean midrange, airy treble, and standout micro-detail retrieval for the price. There’s adequate measured bass, yet the added brightness trims some perceived slam, so it’s not for bassheads. Compared with earlier Kiwi planars, it feels more tonally correct, carrying that planar crispness without the shout or glare that often trips sets up around the mid-treble.

In A/Bs, Aether trades blows with Aöso: the latter reads a touch better tuned, but Aether pulls ahead in technicalities—micro-nuances, textural cues, “whispers.” Melody is warmer but less accurate; S08 is darker and cheaper but less balanced; S12 variants push more 5–6 k energy; MP145 is impressive yet bulkier. Overall, Aether scores roughly an 8/10 with a clear note: choose it for a mid-focused, detailed presentation and excellent value in the planar field, skip it if the priority is big bass weight.

The Kiwi Ears Aether brings a balanced tuning with a thumpy, well-textured low end, clean vocals, and airy treble. Its large planar driver behaves with a DD-like timbre—more grounded than the typical light, floaty planar feel—so bass hits are punchy yet quick, with no bleed into the mids. Vocals sit naturally (neither shouty nor recessed), and the midrange reads clean and well-layered. Up top, extension and micro-detail are strong without fatigue; there’s a touch of extra sparkle that makes the set slightly brighter-leaning without turning sizzly.

As a mid-volume listen (~65 dB), Aether scales well: energetic K/J-pop or rock/metal with busy cymbals may ask for a notch down, while alt-pop, hip-hop, R&B, indie, and ballads benefit from the clarity and control. Versus smoother planars like Timeless 2, Aether trails slightly in sheer timbre naturalness but returns with a bit more treble detail and overall snap; compared with nozzle-tuned rivals, it threads a cleaner, better-extended middle ground. At around $170, its technical performance and planar bass that doesn’t sound planar make for compelling value—slotting neatly between bass-heavy and leaner sets, delivering texture, impact, and clarity without harshness. Recommended.

Kiwi Ears Aether hits with a 15.3 mm planar that feels more like a compact headphone than an IEM—big, airy, and unapologetically wide. Bass is unmistakably planar-fast with real sub-bass reach, while the top end adds a little sparkle without turning shouty. The midrange stays clean and clear, giving that “speaker-like” scale that makes Pink Floyd, Prodigy, or film scores feel expansive rather than congested.

Build and ergonomics lean large but smart: a roomy shell (no dreaded “wing of death”) that seems to help the staging, a tasteful stone-gray faceplate with pops of color, and a soft, flexible stock cable—nice, though it’s 3.5 mm only. Isolation is decent for a mostly closed design with discreet vents, and the set proves easy to drive, yet still scales audibly with a balanced cable and a solid source. Tip rolling shifts the flavor from relaxed and silky to a touch more forward; either way the presentation stays smooth, wide, and fast.

Value seals it: after guessing around $220 on sound and presentation, the real-world street price sits roughly in the ~$150–$170 bracket, making this an easy recommendation under $200. Aether stands out among planars for being big, relaxed, and immersive rather than in-your-face—great for music benders and late-night movies alike. Unique tuning, legit sub-bass, and that effortless planar snap put it firmly on the short list.

Kiwi Ears Aether lands as a standout at the $150 mark: a single large planar driver in a comfy, 3D-printed resin shell that can be worn for 8+ hours without fuss. The faceplate looks premium, the nozzle size is easy, and the sonic profile is smooth, clean, and engaging. Bass is punchy yet controlled—never bloated, never overly warm—while the stage sits in that gaming sweet spot: not too close, not too far. For music, it’s a crisp, non-fatiguing listen with clean mids and technical, tidy low end.

In games, Aether brings the goods: footsteps are elevated with urgency, imaging feels holographic (including vertical cues), and separation/layering remain intact when the action heats up—decisively clearer than Etude and Atheia. Across titles—CoD, Apex, Valorant, Siege, CS, Fortnite, Rivals—it consistently reads space and depth, only giving up a sliver of micro-detail in the densest, high-rank lobbies. That’s why it earns a B+ (borderline A-) on the WallHack Certified list. Astral at $300 still adds that last bit of clarity, but Aether is the top pick under $150; even compared to the Orchestra Lite, it’s similarly capable, more comfortable, and better value.

Think big planar energy: fast, deep sub-bass, a touch of sparkly treble, and a surprisingly speaker-like scale for a single 15.3 mm planar. The stage feels wide and “outside the head,” delivering that easy, expansive presentation without shoving details in the face. It’s the most relaxed-sounding planar IEM vibe—still quick and clean, but mellow enough to binge Pink Floyd, Prodigy, or movie soundtracks without fatigue.

The shells are huge yet comfy (no “wing of death”), with a gray stone-slab faceplate sprinkled in color and a metal rim—gorgeous in a low-key way. Stock cable is soft and usable but 3.5 mm only; thankfully it’s 2-pin, so a balanced swap wakes things up nicely. Isolation is decent despite a few vents, and the set proves easy to drive while still scaling with better sources. Packaging goes full silver overkill: neat tips selection and a pocketable case that does the job.

Value lands hard: street pricing around $150–170 makes this an under-$200 no-brainer for anyone craving planar speed with a big, airy, non-shouty presentation. The Aether stands out as unique in the planar crowd—wide yet fast, smooth yet detailed, with real sub-bass grunt—equally at home for late-night albums, action flicks, or a long flight.
