【1DD+3BA HYBRID STUCTURE】The nozzle structure of PURE, which incorporates a filtering function, is created using high-precision DLP-3D printing technology.This design, combined with an accurately calculated RC frequency crossover, results in a hybrid three-frequency crossover system that allows each of the four drivers to effectively perform its designated role under different corresponding nozzles. 【Superior Objective Measurements】PURE has made significant adjustments to various components of the audio system, including the frequency divider, drivers, damping, cavity, and cable.These modifications aim to reduce the Q value of the resonance peak in the upper high-frequency range while also optimizing bass gain for a better listening experience. 【Classic DLP 3D Printing Technology】DLP 3D printing cavity, from HeyGears, utilizes high-transparency resin, featuring internal coloring and advancedsurface grinding technology. The design achieves an exquisite soundnozzle structure that is challenging to produce with traditionalmethods, resulting in a lightweight cavity made from skin-friendlyand reliable materials. 【Reliable lD Design】The PURE mirrors the design of the HEXA, showcasing a combination of square and rounded shapes. lt employs multiple high-precision processing techniques to enhance the surface textures of various components, improving the overall aesthetic. Additionally, the pressure vent design has been optimized, and the housing size has been minimized while maintaining reliable wearability, thereby reducing discomfort during prolonged use. 【High-quality Cable Stable Extensibility】PURE features a high-quality copper coaxial cable that is oxygen-free and silver-plated, tailored to the tuning style, and incorporates a universal 0.78 2Pin port (0.78 2Pin sunken female socket).This design facilitates outstanding sound quality and allows users to explore endless possibilities by swapping cables.
