The earphone casing is made of skin-friendly resin, with a precise 3D printed cavity and a panel hand-painted with unique colors. It is the perfect combination of RIE-880, created after numerous comparisons and adjustments by Ranko engineers. The Uni-Q coaxial design is adopted to improve interference from stethoscope effects.

At times, it delivers a refreshing sensation like thunder, while other times it offers a tranquil feeling like listening to gentle rain. The overall sound stability of the RIE-880 is high, resembling that of high-end earphones. Even with a large dynamic range, it maintains clarity and avoids interference from different frequency ranges. The soundstage is balanced and well-rounded, creating a sense of immersion. The high frequencies are delicate and graceful, with precise handling of fine details without any muddiness. The mid-range is solid, delivering excellent performance for both male and female vocals.
