Youtube Video Summary
Moondrop Chu 2 keeps the bargain spirit alive with a tidy kit: decent silicone tips, a leatherette pouch, and a surprisingly nice stock cable that feels premium for the price—though the missing chin slider is a small annoyance. Build is where it flexes: a full aluminum shell with brass nozzles and removable filters that invite easy tweak-mods or replacements. Comfort is better than the weight suggests, with the over-ear cable and earhooks distributing mass well—this one even passes the tiny-ears test. Aesthetically it’s classic Moondrop: understated elegance that reads more like functional jewelry. The big caveat: those brass nozzles can show oxidation/corrosion in humid climates, so a silica gel packet or dry storage is smart.
Tonally it’s a mild V-shape done right: boosted bass that’s punchy yet controlled, clean mids that sit a touch back without sounding off, and energetic upper-mids/treble that bring clarity without tipping into harshness for most. Technical chops are solid for the price, with imaging and stage that sit slightly above average. In the budget landscape it parks squarely between the 7Hz Zero (leaner, brighter) and the QKZ x HBB (warmer, smoother)—a middle-ground tuner that suits almost any genre. At about $19, it’s an easy “Brilliant” tier pick and a top first-IEM recommendation or tough beater pair; the only real hesitation is that humidity caveat. Add spring tips or a nicer case and it would nudge even higher.

Youtube Video Summary
Moondrop Chu II keeps the tiny, all-metal shells from the original and fixes the biggest gripe: a replaceable 2-pin cable. The new cable is thin, lightweight, and very well-behaved with small hardware; the only knock is the missing chin slider. The earpieces are small, secure, and comfortable—impressively built for $19. The paint pattern isn’t as distinctive as before, but the ergonomics and cable quality make this a smart budget pickup (and even a handy donor cable for lightweight IEMs).
Tuning shifts from the original’s bright-neutral profile to a more V-shaped, bass-emphasized sound that will appeal to more listeners, while still carrying a slight bright tilt. Frequency response is sensible for the price, but technical performance is merely average—a bit low-res next to options like the 7Hz Zero. Net result: an IEM that sounds fine but wears excellently, with the cable and form factor doing the heavy lifting. It earns a confident 4 stars on value and usability, even if sonic uniqueness takes a back seat.
