Moondrop Chu II (Chu 3) Dynamic Driver In-Ear Monitors (IEMs)
Discover pure audiophile-grade sound with the Moondrop Chu 3, the third-generation evolution of the industry-defining “Chu” IEM series. Engineered with a custom 10mm dynamic driver, an aerospace-grade Aluminum-Magnesium (Al-Mg) composite diaphragm, and a high-flux N52 magnetic architecture, the Chu 3 delivers breathtaking high-resolution audio, lightning-fast transient response, and ultra-low distortion.
Next-Generation 10mm Dynamic Driver & Al-Mg Composite Diaphragm
At the heart of the latest Chu series IEM is an upgraded 10mm dynamic driver system built on an aerospace-grade Aluminum-Magnesium (Al-Mg) alloy dome composite diaphragm. Traditional budget in-ear monitors often compromise on cone rigidity, which leads to unwanted flex, sluggish transient speeds, and high-frequency harmonic distortion. By deploying a true metal-matrix Al-Mg dome, this driver achieves extreme stiffness with minimal mass. This allows the diaphragm to start and stop instantly when responding to electrical signals—delivering ultra-fast micro-details, pristine clarity, and punchy, tight sub-bass without mud or bloat.
– 10mm Al-Mg Dome Composite Driver: Combines extreme rigidity with ultra-lightweight performance for deep, authoritative bass, expansive soundstage, and effortless micro-detail retrieval.
– Precision CNC-Machined Brass Nozzle: Controls treble standing waves and eliminates acoustic volume errors for accurate, natural timbre.
– N52 Neodymium Magnetic Circuit: Delivers over 1.5T of magnetic flux alongside a CCAW voice coil for ultra-fast transient speed.-
– Pop AVG-DF (JM-1) HRTF Target Curve: Professionally tuned to offer authentic three-dimensional soundstage imaging and smooth treble extension.
– Ergonomic Zinc Alloy Shells: Ultra-small, bean-shaped metal cavities cast from high-density zinc alloy provide fatigue-free comfort and long-term durability.
– Detachable 0.78mm 2-Pin Cable: Easily upgrade your cable or transform your IEMs into a wireless setup with Bluetooth ear-hooks.
