Gizaudio x Binary Chopin VS Tanchjim Fission

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.

The Tanchjim Fission presents fantastic value right out of the box, largely thanks to its inclusion of a high-quality USB-C DAC cable with 3.5mm and 4.4mm terminations. The all-metal build feels premium, and the included cable is extremely silky and pleasant to use. A standout feature is the set of interchangeable nozzles that allow for sound tuning; the gold nozzle is the clear winner, providing the best balance, while others can make the bass less impactful. However, the fit can be a challenge for some as the shell lacks a pronounced lip, and the nozzles can be tricky to remove and replace.

Sonically, the Fission is extremely close to the more expensive and beloved Tanchjim Origin, offering a smooth, energetic sound with a tonality that is highly enjoyable. It provides a touch of warmth, pristine detail, and good air, making it a set that is easy to recommend and daily drive. When compared to other sets in its price range, it holds its own against competitors like the Dunu Kima (which has better fit and accessories) and the Kiwi Ears Quintet (which offers more bass), though the choice ultimately comes down to personal preference for tonality and the value placed on its tunable nature.

While it doesn't break the so-called "curse of the $150 IEM," the Fission is a strong contender and gets a full recommendation. Its few cons include a fit that may not work for all ears and a bass quantity that some may wish was greater. For those who value its specific sonic qualities, the excellent build, and the incredible package value with the included DAC cable, the Tanchjim Fission is a fantastic and competitive option that is very easy to enjoy.

The Tanchjim Fission presents a neutral, balanced, and clean sound signature that is also described as smooth and full. It offers a very natural and laid-back listening experience, making it a strong option for those seeking a safe, non-fatiguing tuning. The technical performance is solid for its price, with good detail retrieval and instrument separation, though it isn't the most dynamic or sparkly set available.

Tip selection is crucial, with recommendations for the Tri Clear or Final E tips to open up the sound, while the Spinfit CP155 can add a touch more bass. The included tuning switches are largely seen as a gimmick; only the middle silver setting is recommended, as the others introduce a significant sub-bass roll-off. The Fission excels with genres like rock, indie, acoustics, and classical at moderate volumes, but its lack of sub-bass rumble and extension makes it a weak choice for hip-hop, EDM, or rap.

Its greatest strength is its value proposition, as it is essentially a cheaper version of the Tanchjim Origin, sharing the same driver and sound profile for a lower cost. This makes competitors like the Moondrop Kato seem less relevant. However, when compared to other all-rounders like the Juzear 4U or Simgot EW300, the Fission faces stiff competition. The EW300, in particular, offers more bass, tuning variety, and similar technicalities for half the price, making the Fission a tougher sell unless its specific brand of smooth, neutral tonality is exactly what you're after.

The Tanchjim Fission is an absolutely spectacular IEM that feels and performs far beyond its $129 price tag. It comes loaded with a ridiculous amount of customization, featuring three interchangeable nozzles (stainless steel, titanium, and brass) and a four-way tuning switch, creating a potential 12 different sound combinations. The entire package feels flagship-tier, boasting an excellent interchangeable cable system with 3.5mm, 4.4mm, and USB-C terminations, a waterproof bag, and even a keychain tool for adjustments.

After extensive testing, the definitive "cheat code" for the best sound is using the brass nozzles with the tuning switch set to Pop mode, which seemingly bypasses internal circuitry for a pure, direct sound. This configuration delivers exceptional clarity and a surprisingly wide soundstage, though they are not bass monsters. The fit is excellent, passing the "pinky test," and the build quality on everything from the IEMs themselves to the accessories is exceptional.

While not every combination of nozzles and switches is a winner, the sheer number of options ensures you can find a sound you love. For the price, the value is unmatched, feeling like a product that should cost $279. It comes as a full recommendation, offering a premium, highly tunable experience that is arguably one of the best deals in the IEM market, cementing Tanchjim's reputation for making no bad gear.
