Aluminum-Magnesium Alloy Dome Composite Diaphragm
As a dome diaphragm material, Al-Mg alloy 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.
Hitherto, use of this Al-Mg alloy material was limited to a few high-end in-ear headphones and full-size headphones. It was considered a relatively costly diaphragm material, and the
"CHU II" is the first budget IM to make use of it.
Alloy Casting Cavity
The acoustic cavity of the "CHU II' is manufactured using MOONDROP's mature alloy 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.
Wide-band Response Benchmark Tuning
"CHU II" was tuned by senior acoustic engineers and audiophiles with rich knowledge and wide experience, and exhibits an excellent frequency response curve in line with the VDSF Target Response. The aluminum-magnesium alloy dome diaphragm delivers a natural refined sound, rich timbre and imaging, and an ultra-wide response frequency band.
Ultra-low Nonlinear Distortion
Thanks to the solid technology and meticulous design of the diaphragm material, "CHU II' offers a nonlinear full-frequency distortion below 0.05%, resulting in natural timbre and the reproduction of even the sublest details.
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 ear-hooks for different usage scenarios.
