Moondrop CHU2 / CHU 2 / CHU II Dynamic Driver in Ear Monitor Earphone

Aluminum-Magnesium Dome Composite Diaphragm

As a dome diaphragm material, Al-Mg exhibits high rigidity and light weight, thereby extending the treble bandwidth and revealing more subtle details. The diaphragm suspension is composed of two polymer materials with differing characteristics, resulting in a punchier bass and greatly reduced nonlinear distortion.

Moondrop Casting Cavity - Ensuring Durability and High-Quality Texture

The acoustic cavity of the "CHU II" is manufactured using MOONDROP's mature casting technology, ensuring both rigidity and fine texture. A durable paint layer protects the metal shell from corrosion.
_
Brass CNC Acoustic Nozzle

The nozzle of the "CHU II" consists of a separate brass CNC component, offering higher precision and density, and resulting in beautiful timbre.
_
Replaceable Acoustic Nozzle

"CHU II" incorporates a new generation of replaceable acoustic filters. The front end of the brass nozzle is detachable, allowing users to replace the acoustic filter quickly and conveniently.
Replacement is far easier compared with existing multi-layer filters, and the design makes for greater reliability. In the event of blockage or damage, the cost is much lower than that of standard nozzles.
_
Interchangeable Cable Design Wide Adaptability

CHU II uses a universal 0.78mm interchangeable cable, allowing users to replace the cable or make use of Bluetooth neckband/TWS earhooks for different usage scenarios.
