SODA 1DD+4BA Hybrid In-Ear Monitor 3-Way Frequency Division Wired Earphone | Audiophile IEM with New Silk System & Pure Armature Driver, High Transduction Efficiency, Detachable 3.5/4.4mm

PURE Series BA DriverAddressing the limitations of conventional BA drivershigh distortion, fixed impedance, frequency response constraints, and limited tuning flexibilitythe PURE Series achieves low distortion and high conversion efficiency, featuring characteristics aligned with TANCHJIM's target curve. The high frequencies extend naturally and smoothly. This is not a generic component, but a BA driver designed specifically to pursue higher performance.; Silk System Microstructure Optimizing High-Frequency Smoothness Conventional sound-absorbing materials cannot adequately handle the subtle irritation felt in the 16kHz to 23kHz frequency range. Therefore, SODA achieves finely detailed, continuous, and silk-like smooth high-frequency reproduction by enclosing the resonance chamber in a structure close to the BA driver, arranging multiple stepped microchambers in series, and tuning each individually.

; HPFD-Seg 3-Way Precision Crossover SystemBy more effectively utilizing each driver's performance window, it achieves low distortion, accurate response, and cohesive dynamic expression. The driver system, designed specifically for SODA, enables the crossover network to deliver higher performance ceilings and richer detail without sacrificing sensitivity for frequency correction, while maintaining high driveability.; Physical Filter Structure + Dual Ear Pressure Management System Using high-precision DLP 3D printing technology, we fabricate the physical filter
