CHU II
3.5mm wired in-ear monitors
MOONDROP CHU II keeps a portable wired setup straightforward: compact metal earphones, a detachable cable and a standard 3.5mm plug. It is a practical starting point for listeners who want an IEM without another device to charge.
- 10mm
- Dynamic driver
- 3.5mm
- Analogue plug
- 0.78mm
- 2-pin cable
A composite diaphragm at its centre
The dynamic driver uses an aluminium-magnesium alloy dome composite diaphragm. MOONDROP tunes the acoustic design around its VDSF target response.
Metal housing, machined nozzle
CHU II pairs a zinc-alloy shell with a brass nozzle and replaceable acoustic filter. The small construction sits close to the ear rather than adding a large housing.
Choose the tips, then the playlist
The supplied small, medium and large tips help you find a secure seal. Proper fit matters for bass, comfort and passive isolation.

Before you choose
Is this the USB-C DSP model?
No. This CHU II listing uses a 3.5mm analogue plug. Choose CHU II DSP if you want the USB-C version.
Can I use it with a phone without a headphone socket?
Yes, with a compatible headphone adapter or DAC. Check that the adapter supports your phone and a 3.5mm headphone output.
Can I replace the cable?
Yes. CHU II uses detachable 0.78mm 2-pin connectors. It is not a Bluetooth earphone.
