Short answer: a tie on sound quality. Both are rated 3.8/5 (#564 and #611 of 1291 in-ear headphones) at nearly the same price ($18 vs $16.99), so choose on features and fit.
The case for the TANGZU Wan’er S.G: 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 tradeoff: 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.
Why pick the TRN MT4 Pro: A broadly balanced tuning with a preference score of 71 against the Harman target. The tradeoff: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the TANGZU Wan’er S.G or the TRN MT4 Pro on features: they are rated the same for sound quality at close to the same price.

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.
