Moondrop's entry set: metal build, disciplined tuning, famous pedigree.
A 10mm dynamic with an aluminum-magnesium diaphragm, CCAW coil, and N52 magnet in a zinc-alloy shell. The brass nozzle carries a replaceable acoustic filter, and unlike the original Chu, the 2-pin cable detaches. Reviewers describe a mild V leaning bright with a controlled ~10dB bass lift.
Metal where it counts: Zinc-alloy shell and brass nozzle at an entry price.
Replaceable acoustic filter: Swappable if it clogs — rare at this tier.
Two versions: Standard CHU II (3.5mm) or CHU II DSP with a Type-C cable.
Who it's for
Moondrop's measured, slightly bright tuning philosophy at the bottom of the price ladder.
The honest trade-offs
The brass nozzle can oxidize in humid climates (cosmetic), box accessories are minimal, and bassheads will find the low end polite.
