x Effect Audio FORCE 2DD Audiophile Single-Crystal Copper HiFi Wired IEM | EFFECT AUDIO Co-Developed Cable, Open-Back Cavity, Patented Air Release Vent, Lightweight, 3.5/4.4mm/Type C, Support APP

Hybrid Dual Dynamic Drivers with Composite DiaphragmsAdopting the DMT4 ULTRA dual dynamic driver. The PU suspension provides a flexible and elastic bass response while preventing harsh metallic coloration in the highs, resulting in a more natural and refined sound. The beryllium-coated dome offers high rigidity and low mass, enhancing high-frequency extension and detail. The titanium-coated dome effectively suppresses breakup vibration and reduces distortion during dynamic passages.; High-Precision Segmented Frequency Crossover TechnologyWith HPFD-Seg (High-Precision Frequency Division) technology, FORCE precisely controls the operating range of its 8.2 mm and 10mm dynamic drivers within their optimal low-distortion performance windowclosely matching the target amplitude-frequency response.

During the crossover process, sensitivity loss is minimized to maintain high electro-acoustic conversion efficiency, with a total harmonic distortion (THD) is just 0.036 % THD at 1kHz.; EFFECT AUDIO Co-Developed CableDeveloped by TANCHJIM and EFFECT AUDIO, this premium cable is based on NEOTECHs UP-OCC (Ultra-Pure Ohno Continuous Cast) single-crystal copper technology. It features four strands of 26AWG silver-plated monocrystalline copper conductors, meticulously hand-braided for superior consistency and performance. The internal structure is acoustically tuned to enhance high-frequency clarity while maintaining a solid, full-bodied low end with deep, powerful extension.
