Chu II
Lab summary
"Entry-level classic with balanced sound."
Measurement Context
Moondrop Chu II sits in the $0-$50 IEM range with a Dynamic layout built around 10mm Dynamic. That combination matters because driver topology, impedance, and sensitivity decide how easy the set is to drive and what kind of transient behavior listeners should expect before looking at measurements.
On paper, this unit lists 18Ω impedance and 119dB sensitivity, so source matching should be judged alongside its VDSF Target tuning reference. The GK AudioLab database keeps these fields visible on one page so shoppers can compare electrical load, target curve, and driver count without relying on marketing names alone.

Where It Fits
Driver architecture
Chu II combines 10mm Dynamic hardware with a Dynamic category target, so it should be compared against models with similar topology before brand preference is considered.
Drive behavior
18Ω impedance and 119dB sensitivity make source matching part of the buying decision, especially for phone, laptop, USB-C dongle, and small desktop DAC setups.
Tuning reference
The VDSF Target reference gives this page a repeatable measurement anchor, while the verdict field captures the practical listening angle GK AudioLab uses for database comparisons.
