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 Tangzu Tian Peng offers a V-shaped sound profile that leans towards reference while maintaining musicality, with bass quality being notably source-dependent - it requires amplification to achieve its full physical impact potential. Mids take a step back but remain clean and detailed, while treble presentation varies significantly with eartip choice, becoming bright with Noble tips but more controlled with Azla or Divinus alternatives. Its technical performance shines through strong detail retrieval and decent separation, though the soundstage extends only slightly beyond the head in a circular presentation.
This IEM demands careful system matching as its tonality shifts substantially with different sources, presenting warmer with DAPs like Hiby R6 Pro Max or ONIX xm10 ltd but potentially cold with reference gear. The bone conduction driver contributes to its unique texturing and clarity enhancement according to manufacturer claims, though the overall signature remains heavily influenced by source pairings. Comfort proves a strength with its lightweight resin build enabling extended listening sessions.
