Tanchjim Fission Starlight

Audio-In Reviews hears solid kick impact, punch and tactile bass dynamics, with the default and silver/copper nozzle options providing the most low-end weight. However, the bass-to-low-mid transition is described as less than perfectly clean, and AV Atmos finds sub-bass notably lacking and the low end insufficient for listeners wanting stronger impact.

The lower-mid warmth gives male vocals and instruments useful weight, while vocals are generally described as natural in timbre and tonality. That added low-mid energy can also make the presentation slightly congested, and AV Atmos cautions that listeners seeking a thick, full-bodied midrange may find it too lean.

One reviewer finds the treble neutral and natural, with enough bite for percussion and strings without turning harsh, plus sufficient air and shimmer. AV Atmos hears a more neutral-bright balance and warns that a revealing or harsh source can make the upper range overly intense.

Detail retrieval and microdetail are clear strengths, particularly for a single-dynamic-driver design, and AV Atmos recommends it to listeners seeking nuance in recordings. Audio-In Reviews considers its overall detail level good but more average than exceptional for its price, while source matching matters because excessive brightness can become fatiguing.

The stage is described as average in scale, with depth leaning somewhat intimate rather than expansive. Left-to-right placement is easy to follow, and images retain good focus within that more compact presentation.

Bass attacks are said to have solid energy, punch and tactility, helping rhythmic material maintain momentum. The reviews otherwise say little about large-scale dynamic swings or driver integration, though the Fission is broadly considered a capable and versatile performer.

Audio-In Reviews reports that the Fission fits their ears well, with no seal instability or bass loss attributed to fit. The supplied assortment of tips should provide some flexibility, although more reviewer experiences would give a clearer picture across ear shapes.

The metal shells are described as robust yet lightweight, and the reviewer specifically found them comfortable. No pressure points, fatigue, or awkward insertion issues are reported in the supplied reviews.

The reviews do not provide meaningful comments on passive noise isolation. Buyers needing reliable attenuation for commuting, travel or stage use should seek additional fit and isolation impressions.

The lightweight metal construction feels robust, while the soft, manageable cable is singled out as unusually good for the price; another reviewer likewise calls it well made. The package includes several ear-tip sets, three tuning nozzles, a tuning tool and modular 3.5 mm, 4.4 mm and USB-C terminations, though the included pouch is less protective and convenient than a proper case.

At the stated $130 price, reviewers regard the accessory bundle and overall package favorably, with Audio-In Reviews calling it good for the price point. Its adaptable tuning, modular cable and capable neutral presentation make it competitive for listeners who prioritize clarity over deep bass weight.
