C- Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.

Moondrop Chu Reviews
An extremely well-tuned neutral IEM with a slightly bright and metallic tilt. Crin Youtube Channel
Very well tuned and natural Treble uneveness Tim Tuned Youtube Channel
Comment: Moondrop's best budget IEM. Neutral bright tuning, decent clarity at this price Technical performance in the absolute sense without price considered, gritty treble
A bit uninspired at this point, but no less a solid listen. Precogvision Youtube Channel
Beaten by Salnotes Zero for my library. Good tuning, medriocre techs, but throwing punches up to 100$. Hard to fault. Cable is bad but workable.
