The verdict

The Moondrop Chu III is a fully metal IEM under $30 with a slightly vocal-forward sound that works well for music and casual gaming. However, the isolation is below average for IEMs, and it isn't great in competitive FPS gaming. It's a solid starting point, especially for the price, and most people will enjoy how they sound.

✓Liked: Price, Great sound, Replaceable cable

✕Could be better: No USB-C version, No in-line microphone, Not great for competitive FPS Gaming
