7.8
Reviewer Score
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.

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
