Moondrop Chu III IEM Dynamic Driver In-Ear Headphones Black - 3.5mm

Redefining Entry-Level Listening

The Moondrop Chu III builds on the legacy of the Chu series, one of the brand’s most trusted entry-level IEM lines. With a refined premium exterior, upgraded driver technology and precise acoustic tuning, it delivers a complete and capable listening experience for everyday music, monitoring and gaming.

10mm Aluminum-Magnesium Alloy Dynamic Driver

The Chu III features a 10mm dynamic driver with an aluminum-magnesium alloy dome diaphragm. Its lightweight, rigid construction extends treble bandwidth for finer detail, while the dual-polymer composite suspension provides punchier bass and reduces nonlinear distortion for a cleaner, more natural sound.

N52 Magnetic Circuit and CCAW Voice Coil

An N52 neodymium magnet with a remanence of over 1.5T works with a lightweight CCAW voice coil for higher driving efficiency, faster transient response and enhanced subtle dynamics. This combination helps reveal small musical details with clarity and impact.

Precision Brass CNC Nozzle

The Chu III uses an independent brass CNC nozzle engineered for improved acoustic accuracy. The high-density brass construction reduces volume variation within the acoustic structure and controls treble standing waves for a cleaner, more precise high-frequency response.

Durable Alloy Casting Cavity

The acoustic cavity is made using Moondrop’s alloy casting technology, providing a rigid structure and refined texture. A durable paint layer helps protect the metal shell from corrosion while maintaining its premium appearance through daily use.

PopAvg-DF (JM-1) Tuning

The Chu III is tuned to closely follow the PopAvg-DF (JM-1) target curve using the B&K 5128 measurement system. This tuning approach delivers extended treble, dimensional imaging and a natural, smooth timbre suited to music listening, audio monitoring and professional e-sports.

Ultra-Low Nonlinear Distortion

The upgraded driver achieves full-frequency-band nonlinear distortion below 0.05%. This supports a more natural tonal character, richer subtle detail and improved clarity across the frequency range.

0.78mm Interchangeable Cable

The Chu III includes a universal 0.78mm interchangeable cable with a detachable 2-pin design. Users can upgrade the cable or use compatible Bluetooth neckbands and TWS ear-hooks to match different listening situations.

Ergonomic Bean-Shaped Shell

The ultra-small bean-shaped cavity uses ergonomic curves designed to fit naturally in the concha of the ear. It minimizes discomfort during extended listening sessions, whether for commuting, work or all-day use.

Minimalist Silver and Black Finishes

The Chu III is available in Silver and Black, with carefully finished surfaces that create a clean and premium texture. Its understated design preserves the recognizable minimalist identity of the Chu series.
