Comparison Notes

Moondrop Chu II and Tangzu Wan'er SG 2 solve the same IEM buying question from different hardware starting points. Chu II uses 10mm Dynamic, while Wan'er SG 2 uses 10mm PET Dynamic, so the comparison should start with architecture before moving to price or brand preference.

At least one sensitivity value lacks a voltage/power reference or is unconfirmed. These numbers cannot rank loudness, amplifier needs or sound quality.

Sensitivity is stated per RMS volt. Preserve any stated test frequency and tolerance; it is not directly comparable with a per-milliwatt figure.

Tangzu Wan'er SG 2

Manufacturer: TANGZU · Source checked:

The manufacturer page has conflicting blocks: 19Ω / 113.5dB in the SG2 description and 20Ω / 107dB in a generic specification block. Electrical fields are withheld until the applicable revision is clarified.
