Good tonal balance and technicalities, but decay is truncated which results in etched timbre. Dynamics are also dull. Precogvision Youtube Channel

Metalic timbre with fast decay. A little more enphasis around 4.5k than I would like, but overall pleasent tuning. Very technical, just lacking some dynamics and treble refinement.

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

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.
