Model overview based on user reviews  
Moondrop Chu II are wired in-ear monitors with clear, balanced sound and a replaceable cable, making them easy to drive from common devices. The package includes three ear-tip sizes and a compact case, but noise isolation is only average, the case offers limited protection, and prolonged use may become uncomfortable. One user found the sound too muffled, while another reported that the left driver stopped working, so impressions of sound and reliability are not completely consistent.

I don't know, I'm so lucky.

Normal sound
the left speaker started working
Ilyause Moondrop Chu II more than year
I definitely do not recommend it.
18 August 2024 
Kind of dull. Tried all available eartips: Clarion, Nrn, Tangzu, Latex, Wizzer. The reaction was the same. Meaning if there’s no sound in them, there will be none. Tried both DAC and players. Then I compared them with my Kinera Celest Phoenixcall and decided to throw them in the trash!
There are no advantages.
absolute waste of money.
use Moondrop Chu II month or more i recommend it don't buy

Popular questions

Verified 31 august 2026, Olexandr Cherkashchenko

Does the Moondrop Chu II need a separate amplifier?

Usually not: the 18-ohm impedance and 119 dB sensitivity provide sufficient volume from a smartphone, laptop, or basic audio adapter. An amplifier is only worthwhile if the source itself produces noticeable noise or does not provide the required volume level.Source:SpecificationsExpert reviews

Will they work with a smartphone without a 3.5 mm jack?

Moondrop Chu II connect via a 3.5 mm mini-jack, so smartphones without such a port will require an adapter with a DAC. With devices that retain an audio jack, the headphones can be used directly.Source:SpecificationsExpert reviews

Does it make sense to replace the original Moondrop Chu with the Chu II?

There is no need to rush to replace the previous version if it fully meets your needs. The main practical reason to switch is the detachable cable with a 0.78 mm two-pin connector: if it is damaged, it can be replaced separately.Source:Expert reviews

Does the Moondrop Chu II have a microphone for calls?

The specified configuration is listed as including an in-line microphone. However, the review tested the version without a microphone, so before purchasing, it is worth checking the specific modification and its configuration.Source:SpecificationsExpert reviews

How comfortable are they for extended listening?

Moondrop Chu II are designed for an over-ear fit, which helps keep the earphones in place, but their metal housings weigh about 8 g each. In a review, they were considered comfortable for more than an hour; however, discomfort may occur after several hours due to pressure in the ear.Source:Expert reviews
