Short answer: the TANGZU Wan’er S.G II. It ranks #453 of 1061 in-ear headphones by sound quality, rated 3.9/5, at $24. The TANGZU Wan’er S.G ranks #471, rated 3.8/5, at $18, $6 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the TANGZU Wan’er S.G II: A very cheap single dynamic IEM, the second generation of the TANGZU Wan’er S.G. The catch: Treble sits about 4.0 dB below target, a dark, relaxed balance.
What the TANGZU Wan’er S.G does well: Crinacle’s measurement gives it a preference score of 71, and squig.link measurements show bass and midrange within about 1 dB of target from 20 Hz to 3 kHz, so voices and instruments sound natural at a very low price. The catch: Across 25 hobbyist measurements presence and treble sit about 3.5 to 4 dB below target from 3 to 10 kHz, with a 7 dB dip near 6.3 kHz, so cymbals and fine detail sound a bit softened.
Buy the TANGZU Wan’er S.G II. It is rated higher for sound quality, and the $6 you would save on the TANGZU Wan’er S.G does not close the gap.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.

TANGZU Wan’er S.G: $18.00 Amazon $18.00 Lowest AliExpress $19.00 eBay
Newer model: the TANGZU Wan’er S.G 2, ranked higher, rated 4.2/5, released Mar 2025. See every Tangzu Wan’er SG generation.
Pros: Crinacle’s measurement gives it a preference score of 71, and squig.link measurements show bass and midrange within about 1 dB of target from 20 Hz to 3 kHz, so voices and instruments sound natural at a very low price. Each earbud weighs 4.2 g, and a built-in microphone handles calls. It rates above the KZ ZST and costs less.
Cons: Across 25 hobbyist measurements presence and treble sit about 3.5 to 4 dB below target from 3 to 10 kHz, with a 7 dB dip near 6.3 kHz, so cymbals and fine detail sound a bit softened. The CCA CRA and 7Hz x Crinacle Zero 2 rate a little higher for only slightly more money.
