Tanchjim Fission VS Crinear Daybreak

Youtube Video Summary

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.

Youtube Video Summary

The CrinEar Daybreak features a metal nozzle and metal faceplate with comfortable contours, though the fit is noted as a bit dainty and small. Isolation is practically non-existent, and the fit isn't particularly secure. The included cable looks nice and photographs well, featuring interchangeable terminations for versatility, but its chin slider moves too easily and isn't recommended for those needing a functional one. The case is deemed aesthetically pleasing and feels good, though not especially premium, magnetically shutting with adequate space.

Sonically, the Daybreak leans boring and somewhat sterile or dry. It offers nice bass and a lot of upper mids, which are done decently with a standard 3K peak. However, the combination of this upper-mid focus and an incisive peak around 8K contributes to a perceived harshness and sharpness, lacking in overall detail retrieval. Graph comparisons reveal its signature has significantly more upper mids and often more bass than competitors like the Moondrop Dusk or TruthEar Nova, resulting in a less engaging listen. Sets like the Defiant, Chopin, and Performer 7 are cited as more engaging alternatives at similar or lower prices, with the Defiant specifically recommended over the Daybreak. Even the Punch Audio martillo and Moondrop Meteor, sharing driver configurations, are considered more fun or better tuned.

Ultimately, the Daybreak is a solid A-minus IEM, well-packaged and a commendable first effort for the brand, but it's not hypeworthy or a benchmark. It lacks imagination and falls short against numerous compelling alternatives around its price point, such as the Performer 7, ZOS Defiant, Chopin, or discounted planar options like the Aether. While a good value, especially if found on sale via Linsoul or the used market, its piercing upper mids and failure to truly excel make it hard to fully recommend over the competition.

Youtube Video Summary

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.

Youtube Video Summary

The Crinacle Daybreak is a technically excellent IEM that offers exceptional clarity and detail retrieval without being fatiguing. Its five-driver configuration delivers a cohesive and precise sound signature that is clean, flat, and incredibly balanced. The bass is present and punchy but never exaggerated, making it a perfect tool for studying music and hearing every nuance in a recording.

However, this precision comes at the cost of fun. The tuning is described as a little dry and somewhat intimate, lacking the expansive soundstage and flavorful character that makes other IEMs more engaging for pure enjoyment. While the build is solid with an acceptable cable and nice connectors, its looks are admittedly boring. It’s a perfectly cooked meal that follows the recipe without any surprises.

Ultimately, the Daybreak is a highly respected and much-loved IEM that fills a specific niche for a clean, reference-like sound. It’s a business suit of an IEM, but it wouldn't be the first choice for someone looking for a more exciting, fun, or "f***ed up" sound signature to get them moving. It commands respect for its technical merits, even if it isn't to everyone's personal taste.

Youtube Video Summary

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.

Youtube Video Summary

The CrinEar Daybreak offers a balanced, clean, and non-fatiguing sound signature, functioning effectively as an all-rounder. Every frequency region is solid, delivering a smooth presentation without harshness or overwhelming warmth. The bass provides a slight sub-bass rumble and integrates cleanly into the mids, avoiding bleed, though it lacks significant impact, slam, or deep texture. Similarly, the mid-range and vocals are well-separated and forward enough, free from congestion or odd timbre, but don't specialize. The treble has enough extension and air, avoiding darkness or excessive sharpness, but misses out on micro-detail, sparkle, and expansive staging. It’s a decent, inoffensive performer across the board, described aptly as a "very good vanilla ice cream cone".

Technically, the Daybreak is competitive but not class-leading. Sets like the Meta, Ziigaat Crescent, Kiwi Ears Astral, Simgot EM6L, or TruthEar Nova offer slightly better detail retrieval, imaging, and resolution. Its main challenge comes from remarkably similar competitors, particularly the EPZ P50 and SLIIVO SL224, which share nearly identical tuning, driver configurations, and technical performance around the same $160-$180 price point. The P50 leans slightly more vocal-centric, while the SL224 offers marginally better bass texture and treble detail (though costing more). If you already own either, the Daybreak becomes largely redundant. Against alternatives like the bassier, more dynamic Ziigaat Odyssey ($200), the Daybreak feels safer but less engaging at higher volumes. Compared to Harman-tuned sets like the Supermix 4, Chopin, or Nova, the Daybreak boasts fuller tonality and less fatigue but gives up some layering and detail.

Ultimately, the Daybreak is a competent, well-packaged all-rounder at $170, delivering a balanced and inoffensive listen suitable for any genre library. However, it fails to stand out uniquely in a crowded field. Its sound signature is replicated almost exactly by the existing P50 and SL224. While it earns a half recommendation as a solid option for those seeking a non-fatiguing all-rounder who *don't* own those twins, it's unlikely to become a favorite due to its lack of distinctive character. Value is decent, but alternatives offer more specialization or technical prowess for similar or lower cost.

Youtube Video Summary

Tanchjim Fission comes in at $130 with a quirky onboard tuning dial that offers four bass positions—but every setting trends toward modest bass anyway, making the adjuster more novelty than necessity. The default “bass-max” profile presents that familiar single-DD contrastiness with a bit of dynamic punch, a slightly bright/forward tilt, and overall inoffensive treble. It never tips into harshness or sibilance, but the bass attack reads a touch pillowy and the whole presentation stops short of truly incisive.

In direct comparison, it’s more comfortable tonally than the spikier sets yet less engaging and less tight than the standouts, settling into a solid C-tier alongside other “fine but unremarkable” options. Resolution and imaging are serviceable, treble stays safe, and the included cable is surprisingly nice, but there’s not enough slam or bite to push it up the chart. Net result: a competent, easy-listen single-DD for those who value smoothness over excitement, with limited payoff from that bass dial.

Youtube Video Summary

The CrinEar Daybreak lands at $170 as the second IEM from Crinacle, positioned as a more accessible follow-up to the limited-edition Meta. This tribrid features a single dynamic driver, two balanced armatures, and two micro planars handling the highs. The build includes compact, semi-custom dark smoky resin shells offering good stability and comfort, though the molding might be slightly aggressive for some. The included cable provides swappable terminations (3.5mm and 4.4mm) but is noted for being somewhat stiff and kink-prone. Accessories are solid for the price, including a leatherette case and multiple tip options, with the stock silicones recommended for optimal fit due to the slightly longer nozzle.

Sonically, the Daybreak delivers what the review calls the best tonal balance yet within the popular "new meta" tuning category. Its frequency response is described as exceptionally neutral and natural from the mid-bass upwards, creating a low-contrast, chill, and non-fatiguing listen with forward, textured vocals and non-existent sibilance. However, this comes with trade-offs: the bass lacks ultimate tightness and slam, and the treble exhibits a light, wispy quality (likened to cotton candy) that lacks some bite and definition. While technical performance like imaging is solid, it doesn't stand out as exceptional.

In direct comparisons with six competitors around $200 (including the Meta, Binary x Chopin, EPZ P50, Ziigaat Lush, Truthear Pure, and Kiwi Ears KE4), the Daybreak consistently ranked highest for tonality. It was praised as a modern benchmark for natural tuning at its price. However, it fell behind in bass physicality and treble incisiveness. Ultimately rated a strong four stars, the Daybreak is highlighted as an excellent choice for those prioritizing a refined, natural midrange and easy listening experience over sheer technical prowess or visceral impact, earning the label of a "modern-day Etymotic ER2XR" with far better comfort.
