MOONDROP CHU III Dynamic Driver IEM with Aluminum-Magnesium Diaphragm

The MOONDROP CHU III is the third generation of MOONDROP’s popular CHU series, developed for listeners looking for detailed and balanced HiFi sound from a compact in-ear monitor. It features a newly refined 10mm high-performance dynamic driver with an aluminum-magnesium alloy composite diaphragm, precision brass CNC acoustic nozzle, zinc alloy cavity, and detachable 0.78mm 2-pin cable.

Building on the foundation of the previous CHU models, the CHU III introduces updated driver technology and MOONDROP’s scientifically measured acoustic tuning. Its lightweight yet rigid diaphragm is designed for fast transient response, extended treble reproduction, controlled distortion, and natural overall tonality.

10mm Aluminum-Magnesium Alloy Dynamic Driver

At the heart of the MOONDROP CHU III is a 10mm dynamic driver with an aluminum-magnesium alloy composite diaphragm. The diaphragm combines low weight with high rigidity, allowing it to react quickly to changes in the audio signal while maintaining good structural control.

This construction helps the CHU III reproduce fine details and extended high frequencies while maintaining controlled bass and a natural midrange. The upgraded driver architecture also contributes to low nonlinear distortion, making subtle information in recordings easier to hear.

Scientific PopAvg-DF (JM-1) Acoustic Tuning

MOONDROP applies its measurement-based acoustic design approach to the CHU III. The earphones are tuned toward PopAvg-DF (JM-1) frequency response characteristics based on HRTF, with adjustments made to maintain a smooth tonal balance, clear imaging, controlled bass response, and extended treble.

The result is a tuning style intended to work well across a wide range of music, including vocals, acoustic tracks, pop, electronic music, rock, and other detail-focused recordings.

Precision Brass CNC Acoustic Nozzle

The CHU III uses a separately manufactured brass CNC acoustic nozzle. The high density of brass and precision CNC machining help maintain accurate dimensions within the acoustic structure.

This design also helps control high-frequency standing waves and reduces variations caused by acoustic volume tolerances, contributing to more consistent treble reproduction.

Durable Zinc Alloy Cavity

The earphone housing is manufactured using an alloy casting process and features a zinc alloy acoustic cavity. The rigid metal construction provides structural stability while giving the CHU III the solid feel associated with the CHU series.

A protective surface finish helps improve resistance to everyday wear and corrosion while maintaining the clean, minimalist appearance of the earphones.

Compact and Comfortable CHU Series Design

The MOONDROP CHU III continues the compact, bean-shaped design philosophy of the CHU family. Its ergonomic shape is designed to sit naturally within the outer ear, helping provide a secure fit without requiring an unnecessarily large housing.

The earphones are offered in Silver and Black, allowing users to choose between two understated metallic finishes.

Detachable 0.78mm 2-Pin Cable

Unlike fixed-cable earphones, the CHU III uses a widely adopted 0.78mm 2-pin detachable cable interface. The stock cable can therefore be replaced when necessary or upgraded according to individual preferences.

The standardized connector also provides additional flexibility for compatible aftermarket cables, Bluetooth neckbands, and suitable TWS earhook adapters.

Easy to Drive with 16Ω Impedance

With an impedance of 16Ω ±15% at 1kHz and sensitivity rated at 118dB/Vrms at 1kHz, the CHU III is designed to work efficiently with common portable audio sources. Depending on the source device, it can be paired with smartphones, laptops, portable music players, USB DACs, or dedicated DAC/AMP setups using a suitable 3.5mm connection.
