Lacks in bass, low pinna gain, but overall not bad, just expensive.

Two units, both have audible channel imbalance. Stage width is average but lacks height and depth. Treble is on the darker side with some 5k energy. Mid bass is a bit too much but good slam. Shows incoherence signs.

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.

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.

  • The tuning leans easygoing, yet occasional unevenness nudges it away from greatness. A bit of EQ polish can smooth things nicely.

Average Technical Grade

C-
  • Textural information blurs together, making the stage feel pinched and gray. Instrument edges blur together frequently.
Bass B
You get a lively bass response that balances energy with discipline. It balances punch with respectable control.
Mids C+
The region sounds agreeable overall, delivering clarity without flashiness. Slight warmth keeps things easy-going.
Treble C

Dynamics C-
It maintains a steady dynamic profile that neither offends nor inspires. Swells arrive but lack drama.
Soundstage B

Imaging C-

Gaming C
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical. Value-to-cost may not be optimal for gaming-focused users.
