Key item features

• 10mm Dynamic Driver with AI-Mg Alloy Dome Composite Diaphragm — high-rigidity, lightweight diaphragm delivers extended treble detail and punchy bass with significantly reduced distortion
• N52 Neodymium Magnet + CCAW Voice Coil — over 1.5T remanence for higher driving efficiency, faster transient response, and enhanced subtle dynamics
• Scientific Tuning (PopAvg-DF / JM-1 Target) — frequency response closely aligned with the popular target curve, measured and adjusted with B&K 5128 professional equipment
• Ultra-Low Full-Frequency Distortion — THD ≤0.1% at 1 kHz / 94 dB for clean, transparent sound
• Brass CNC Acoustic Nozzle — precision-machined independent nozzle reduces acoustic volume error and controls treble standing waves
• Zinc Alloy Casting Cavity — rigid, refined texture with a durable corrosion-resistant paint layer
• Universal 0.78mm 2-Pin Detachable Cable — easily swap cables or use with Bluetooth neckbands / TWS ear-hooks
• Ergonomic All-Day Comfort — ultra-small bean-shaped shell conforms to the ear concha for extended wear without fatigue

About this item

Product details

The MOONDROP CHU III is the third generation of the award-winning Chu series, delivering end-game sound quality in an entry-level in-ear monitor.Built around a 10mm high-performance dynamic driver with an aluminum-magnesium alloy dome composite diaphragm — a material previously reserved for high-end headphones — the CHU III produces extended treble detail, punchy bass, and ultra-low nonlinear distortion across the full frequency band.

Tuned to closely align with the PopAvg-DF (JM-1) target and measured using professional B&K 5128 equipment, the CHU III offers a natural, reference-grade sound signature.An N52 neodymium magnet paired with a lightweight CCAW voice coil ensures fast transient response and high driving efficiency, while a precision brass CNC acoustic nozzle controls treble standing waves for cleaner highs.

Housed in a durable zinc alloy casting cavity with a corrosion-resistant finish, the CHU III comes in two elegant colors — Silver and Black.Its ultra-small, bean-shaped ergonomic shell conforms to the ear for all-day comfort with zero fatigue.The universal 0.78mm 2-pin detachable cable design allows easy cable upgrades or compatibility with Bluetooth neckbands and TWS ear-hooks for versatile usage scenarios.
