MDAQS Overall — measured in the SoundGuys lab.
Plastic is the most common — on 24% of the 49 in-ear monitors we've cataloged (of 39).
Silicone is the most common — on 63% of the 52 in-ear monitors we've cataloged (of 39).
above average for in-ear monitors — based on 23 of 39 we've cataloged.
Objective measurements from the SoundGuys test lab — overlay other models to see how this one compares.
Measured frequency response (dB relative) against the SoundGuys Headphone Preference Curve. When the measurement goes above the dashed line, that frequency is louder than our preference curve, and when it goes below: it's quieter. Use the curve for comparison purposes only, as your taste may vary.

Multi-Dimensional Audio Quality Scores (1–5), modeled from the measured response. Higher is better across timbre, distortion, and immersiveness — add other models to see where this one lands.
The Tangzu Wan'er S.G. are competent in-ear monitors at a meager price. These IEMs exemplify why the bargain in-ear market has such ardent fans.
