Funky and agressive tuning that turns into a detail and dynamics machine for its price - could shine with minor adjustments.

The Kinera Celest Phoenixcall offers a distinctive tribrid driver configuration (1DD+2BA+2 Micro Planar) that delivers an energetic, V-shaped sound signature with pronounced mid-bass impact and bright upper-mids. Bass is punchy and textured, though sub-bass extension rolls off slightly, while vocals and instruments can occasionally tip into shoutiness or sibilance in busy tracks . Technical performance is a mixed bag: imaging and separation are precise, but timbre often feels unnatural with metallic tinges, and the soundstage leans taller than wider .

Comfort and aesthetics are clear strengths. The transparent resin shells showcase internal components artistically, and the included 8-core SPC cable feels premium . However, the thick nozzles may challenge smaller ears, and the provided eartips often exacerbate upper-frequency harshness—tip-rolling is recommended . While the unboxing experience impresses with its themed accessories (including a metal bookmark), the carrying case is notably cramped .

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.

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.
