The DITA Prelude aims for a mild V-shaped presentation that stays easy on the ear: bass has a gentle lift, mids stay clean, and treble adds air without harshness. DITA itself describes the Prelude as mild V with an emphasis on technicalities, which lines up with its relaxed yet open tonality . Treble extension and perceived headroom are standouts at the price, helping stage and layering feel a notch above typical entry-level fare .
Hardware is straightforward: a single 10 mm dynamic driver with a composite diaphragm and dual magnets, plus dual-volume venting for control and consistency . The metal shell is compact and sturdy, and the 0.78 mm 2-pin interface keeps cable options open if you want to swap later . Detail retrieval is good for the bracket; micro-detail won’t challenge kilobuck sets, but separation holds up well in busy tracks.
Value is helped by the bundled ANTE USB-C DAC/amp dongle, which pairs neatly and removes source guesswork for newcomers . Bass is tastefully elevated rather than boomy, so bassheads may want more slam, but the Prelude’s balance and treble smoothness feel well judged for long sessions. Street pricing sits around $159, making it an easy recommendation for a first serious single-DD IEM .

Exact same driver and tuning as the Origin (with middle dial on S-SILVER NOZZLE) but with less premium build/design/cable/case - a welcomed hit for better value. Clean, neutral, balanced, full, and smooth all-rounder. Jays Audio Youtube Channel
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 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 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.

The Tanchjim Fission delivers a notably neutral with vocal-forward presentation in its default configuration, emphasizing clarity and articulation in the midrange without excessive coloration. Bass response is described as clean and firm, offering good texture without bleeding into the mids, while the treble remains smooth and non-fatiguing, contributing to an overall balanced yet engaging listen. Its standout feature is the extensive customization: three swappable nozzle filters (brass for warmth, titanium for brightness, stainless steel for neutrality) and a four-position analog tuning dial collectively enable 12 possible tuning combinations, allowing significant user adjustment to suit genre or preference.
Technically, the Fission leverages Tanchjim’s fifth-generation DMT5 dynamic driver, shared with their higher-end Origin model, which contributes to strong detail retrieval and a surprisingly expansive soundstage for a single-DD IEM at this price. The lightweight CNC-machined aluminum shells ensure comfort during extended use, though isolation can vary and may require tip rolling for an optimal seal. The package includes a practical soft case, a modular silver-plated cable with 3.5mm, 4.4mm, and USB-C (featuring DSP and app-based parametric EQ) terminations, rounding out a strong value proposition at $129.99.
