Youtube Video Summary
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.

Youtube Video Summary
LETSHUOER S12 Ultra wraps up the S12 line with a 14.8 mm planar driver and a familiar metal shell in gunmetal or mocha. The housing is vented, comfy for long sessions, and solidly built with a flat 2-pin interface that grips tips well. The stock package is practical: a soft case, a fair tip spread, a braided cable with swappable 4.4 mm termination, and even a plug-and-play USB-C DAC that performs capably for on-the-go use.
Sonically, this set aims for a mild V-shape with tasteful tweaks that elevate it over prior S12 iterations. There’s a touch more sub-bass than the S12 Pro and a smoother 10 kHz zone, reducing fatigue while keeping upper-treble reach for air. The presentation favors balance over sparkle: detailed without the brittle edge many planars flirt with, and notably non-fatiguing over longer listens. Technical chops are strong for the class—clean, clear, and “planar-fast”—though instrument separation can lag behind pricier hybrids, and the topmost “crispy” sheen is slightly restrained.
On graphs and in practice, S12 Ultra reads as a refined take on modern planars—more bass weight, tidier 4–6 kHz, and better treble behavior than its siblings. Listeners hypersensitive up top may still prefer something like the S15 for a softer treble contour, while those chasing maximal separation may lean to sets like AFUL Performer 7 (with a spicier treble). With the usual planar caveat about unit variance and fit, this edition comes through as the standout of the S12 series: a clean, engaging, and genuinely high-value recommendation under $500.

Youtube Video Summary
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.

Youtube Video Summary
The Letshuoer S12 Ultra comes through as the smoothest tuning in the S12 family— a sub-bass boosted all-rounder with quick transients and satisfying rumble that makes pop, hip-hop, and EDM notably fun. Technical performance sits around earlier S12 variants, but treble detail is dialed back a touch versus the OG/Pro in exchange for a more natural timbre and less “planar-bright” edge. It’s the bassiest S12 to date, hitting with better texture, impact, and extension, while keeping imaging crisp enough to stay engaging rather than clinical.
Tuning tweaks tame the upper range: a cut past 1.5 kHz and an 8–15 kHz dip ease shout and sibilance, with air returning via a lift around 15 kHz. Vocals sit a bit pulled back and the treble is the least energetic of the series, which helps long-session comfort—though brighter, heavily produced tracks or songs with little low-end can still sound peaky if pushed. Best results come at ~65–70 dB; tip-roll toward clear or bass-supporting tips to smooth the top and reinforce the lows, while avoiding brightening tips that exaggerate energy.
Versus peers, S12 Ultra feels like a bassier, less shouty take on Supermix 4/Nova and a slightly more V-shaped, punchier alternative to Defiant. It’s not a value monster for sheer detail compared with cheaper planars (T10, F1 Pro, etc.), but the payoff is a presentation that’s more musical, smoother, and easier to live with. For listeners wanting added slam without losing the S12’s speed and airy sense of space, this version offers the most enjoyable balance in the lineup.

The Gizaudio x Binary Chopin is a hybrid 1DD+3BA design built around an 8 mm ceramic-diaphragm dynamic driver for lows, a midrange BA, and a dual-BA tweeter assembly, targeting a lively, modern tuning rather than strict neutrality . Tonally it leans a bit more V-shaped, with extra sub-bass presence and a touch of lower-treble energy compared to flatter reference sets . Street pricing commonly sits around $199, positioning it squarely in the competitive mid-budget bracket .
In practice, bass is tuned for weight and punch (notably ~50–100 Hz), which adds impact without the delineation of more surgical sets; mids are clean but slightly set back, and treble can show mild peakiness that adds clarity yet may verge on dryness with certain tracks . Stage and imaging are competent for the price—not class-leading, but precise enough to separate instruments in busy mixes according to multiple listener reports . Overall resolution feels appropriate to the segment, with macro-dynamics slightly favored over microdetail.
Build is a mix of stainless-steel faceplates and resin shells, and the set is easy to drive thanks to its 12 Ω impedance and high 122 dB/Vrms sensitivity—beneficial for dongles and phones, though sensitive sources may reveal hiss . Listeners who like a fun, energetic V-shaped balance with solid bass impact and crisp upper presence will find strong value here; those preferring softer treble or more mid-forward vocals may want alternatives in the same price tier .

The Letshuoer S12 Ultra continues the brand’s planar lineage with a 14.8 mm planar-magnetic driver in a compact metal shell. Notable upgrades include a 392-core silver-plated cable with interchangeable 3.5/4.4 mm plugs and even a bundled DT01 Pro Type-C DAC cable in some packages, positioning it as a self-contained portable solution at an MSRP around $169.
Tonally, the Ultra aims for a lively U-shaped balance common to prior S12 variants—crisp upper-treble energy with solid bass presence—while early impressions from show-floor demos frame it as the most refined take yet. That aligns with the S12 family’s reputation for strong resolution and a brisk top-end; the original S12 was praised for technical performance albeit with a brighter tilt, context that helps set expectations for the Ultra’s direction.
As with many planars, the S12 line can benefit from competent source power to realize dynamics and control; community reviews note the Ultra responds well to suitable amplification. Staging remains more intimate than expansive compared to some hybrids, but imaging and micro-detail are competitive at the price, making the Ultra a pragmatic sub-$200 pick for listeners who value clarity and transient speed over warmth.

Youtube Video Summary
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.

Youtube Video Summary
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.

Youtube Video Summary
Final revision of the series brings a very coherent, slightly warmer presentation with treble pulled into safer territory and mids that feel a bit weightier. Ultra sits between the smoother S08 and the rawer S12 Pro, and it comes across a touch bassier than the graphs suggest. As a single-driver planar, it retains solid resolve and a natural, easy tonality that will suit most listeners, especially at the 169 price point.
Despite graphs looking similar to S12 2024, Ultra sounds smaller and flatter, with less transparency and dynamics. Soundstage is mainly left-right; height and depth are curtailed, so placement is not always in the right place on more spacious tracks. The smoother top end avoids harshness and makes long sessions comfortable, but the trade-off is reduced sparkle and air versus the 2024 tuning.
Versus budget planar standouts like KZ PRX, Ultra is a clear, smoother upgrade; versus S12 2024, it is the safer all-round pick but not as open or exciting. Dense mixes can nudge the bass toward a slight bloom and compress the center image. For most, this is the one S12 to buy; stage and transparency chasers may still prefer the 2024 version.

Timmy has really delivered one of the best IEM tunings I have heard. It's clear, punchy, sounds accurate, non-fatiguing and just does everything. I wished there would be a more premium version. Don't like the shells and design.
