Tanchjim FORCE DMT4 Ultra Dual Dynamic Driver In Ear Monitor Earphone

Precision Engineering from Two Legends

TANCHJIM and EFFECT AUDIO have come together to co-develop FORCE, combining TANCHJIM’s mastery of acoustic engineering with EFFECT AUDIO’s cable craftsmanship. Every part of the FORCE, from its custom dual dynamic drivers to its signature silver-plated cable.



Flagship Dual Dynamic Driver Architecture

FORCE houses two custom dynamic drivers: an 8.2mm beryllium-coated mid-high driver and a 10mm titanium-coated bass driver, both using PU-suspended diaphragms. This setup, based on TANCHJIM’s DMT 4 Ultra driver platform, provides powerful bass, detailed mids, and sparkling treble.



Cable by EFFECT AUDIO

The included cable is handcrafted by EFFECT AUDIO using four strands of silver-plated UP-OCC single-crystal copper in a custom coaxial weave. This high-performance cable delivers exceptional signal purity and electrical conductivity, enhancing bass authority and treble extension. EFFECT AUDIO’s UltraFlex™ jacket makes it soft, skin-friendly, and durable for all-day comfort.



Built-In DSP and Custom EQ

The DSP version of FORCE supports USB-C digital output and integrates seamlessly with TANCHJIM’s official tuning app. Users can fine-tune their sound using a 5-band parametric EQ or choose from curated presets including Harman 2013, 2016, and 2019 target curves.
