Introduction: The Continuously Evolving Tanchjim
I've always believed that everyone has strengths, but integrating these strengths naturally into daily interactions is both challenging and meaningful. This explains why some people always make great first impressions, while others, despite being equally talented, remain easily overlooked.
In my mind, Tanchjim embodies this philosophy perfectly. They're a "continuously evolving audio brand" that understands their strengths and invests them into each new product. With the SODA—priced at approximately $300 USD—I see not only the DNA of Origin and Force but also further proprietary innovations.
"Neutralizes acidity (reduces harshness), relieves indigestion (can't stop listening), replenishes hydration (female vocals sound crystal clear)—these are the three magical effects of soda water!"
Design & Build: Sky Blue Elegance
Tanchjim's packaging remains timeless and minimalist. For the SODA, the main color scheme has been upgraded to sky blue to match the "soda water" inspiration. The package includes two types of silicone ear tips and interchangeable 3.5mm + 4.4mm plugs.
The SODA features exquisitely crafted transparent resin shells with an ice-crack pattern effect on the faceplate, cable plugs, and pins. The shell is compact with a longer nozzle—surprisingly secure and remarkably lightweight.

Technical Configuration: 1DD+4BA+2PA Architecture
The SODA employs a revolutionary 1DD + 4BA + 2 Passive Radiator architecture:
- 1 Dynamic Driver: DMT5 composite rear-chamber DD for solid bass foundation
- 4 Balanced Armatures: PURE series mid-high frequency BAs for precise detail
- 2 Passive Radiators: Enhanced high-frequency extension and control
- Silk System Technology: Optimizes 16kHz-23kHz range, eliminating harshness
This unique configuration combines the strengths of dynamic drivers, balanced armatures, and passive radiators for comprehensive audio performance.
Sound Performance: Refreshing as Soda Water
The SODA is a listening-oriented IEM emphasizing smooth refinement, relaxed power, clarity, and warm listenability. It has a slightly warm tonality with substantial thickness across the entire frequency range, minimal aggression, and balanced energy distribution—truly like refreshing soda water: invigorating yet never harsh.
Bass: Spacious, Textured, Well-Controlled
The bass delivers moderate quantity with spacious expansion, excellent layering and body while avoiding muddiness. This lighter, softer-rebound reference-style bass may not provide thick atmospheric immersion, but it's undeniably well-textured and commendable.
Midrange: Signature Tanchjim Style
The midrange vocals showcase signature Tanchjim characteristics: bright, refined, precise, and tight. Both lushness and detail retrieval are impeccable. This is absolutely a female vocal specialist—whether J-pop or Cantopop, the SODA renders vocals with crystal-clear hydration.
Treble: Absolute Strength
Treble is the SODA's absolute forte. These passive radiators deliver treble that's gorgeous, elegant, and seamlessly integrated yet completely free of harshness. Even with OST music dominated by electronic and string instruments, you won't experience fatigue. It achieves the ultimate goal: "treble should sound beautiful without causing fatigue."
Best Genres: J-pop, anime/game soundtracks (ACG), Cantopop, Mandopop, and OST music. Low barrier to entry, easy to appreciate—pure, plug-and-play enjoyment.
Conclusion: Building on Legacy
The SODA inherits Origin's resolution and vocal strengths while incorporating Force's powerful dynamics. Through its new driver configuration, it optimizes treble performance, making it an IEM that delights longtime fans while impressing newcomers—poised to become another safe blind-buy recommendation in this price range.
