Very good all-rounder set with great dynamics on top. Stage is wide with great technical performance. Vocals pop out just enough, bass is tactile with good slam, overall a solid set if you want a more engaging set that does everything very well. Only downside is that it can be a bit sharp with stock tips - highly recommend TangZu Sancai Wide tips, helps smoothens out and open the sound - mandatory for max potential

Clean mids and forward vocals. Light bass impact, upper mids can get intense, and average detail. Mid-forward, neutral-bass sound signature. Not very versatile across genres.

The open back nature of this iem is compelling!

The TANCHJIM x Effect Audio Force employs a dual dynamic driver configuration, pairing a 10mm titanium-coated bass driver with an 8.2mm beryllium-coated mid-high driver. This setup, managed through Tanchjim's HPFD-Seg crossover technology, aims for cohesive integration, delivering impactful low-end while maintaining clarity in vocals and treble. The notable open-back design incorporates a pressure-relief nozzle to minimize listening fatigue, though isolation remains surprisingly effective despite the acoustic vents.

Tonally, the Force leans toward a balanced signature with a mild bass emphasis, avoiding excessive warmth while retaining texture in kick drums and basslines. Treble extension is smooth and non-fatiguing, though some may find airiness slightly reserved compared to brighter tunings. The standout inclusion is the Type-C DSP cable, enabling deep customization via Tanchjim's app—including parametric EQ and Harman target presets—which significantly refines the stock tuning for personal preference.

Technically, the open-back architecture contributes to an expansive soundstage with precise imaging, excelling in complex tracks where instrument separation matters. While dynamics are competent, micro-detail retrieval doesn’t quite match elite hybrid or EST-equipped IEMs in its price tier. The co-engineered Effect Audio cable and ergonomic resin shells ensure long-wearing comfort, rounding out a package that prioritizes refinement over raw resolution.
