TANCHJIM x Effect Audio Force Earphone Dual Dynamic Driver Flagship in-Ear Hi-Fi Headphone

• Dual composite metal dome diaphragmsDMT dynamic drivers for powerful sound and dynamics. Easy to drive. Uses HPFD-Seg High-Precision Frequency Domain Splitting Technology.
• 3D-printed medical-grade resin shellAerospace-grade CNC-machined aluminum faceplate optimized weight distribution for a comfortable fit.
• Open-back rear chamber design. The FORCE’s open-back rear chamber allows reverse sound waves to interact freely with the air, significantly reducing sound quality degradation caused by rear chamber reflections. By dissipating vibration energy, it effectively suppresses distortion. This design also expands both the horizontal and vertical soundstage while enhancing high-frequency extension.
• Dust and Water-Resistant Acoustic Mesh. Featuring a DWR-coated acoustic filter that protects the driver from dust and moisture while effectively smoothing out high-frequency harshness for a more natural treble response. (In addition to the nozzle mesh, the internal damping filters in the FORCE also use this coating to enhance long-term durability.)
• All-New Ergonomic Design. The FORCE features a completely redesigned ergonomic shape that precisely matches the natural angle of the ear canal. This optimizes the direct sound path from the driver to the eardrum, reducing sound reflections and ensuring high-fidelity audio transmission. Additionally, by intelligently distributing weight to the concha support area and earhook pressure points, the design achieves even pressure distribution, significantly reducing localized discomfort. This makes the FORCE table and comfortable even during extended wear.
