Short answer: the Ooopusx OP24. It ranks #68 of 450 in-ear headphones by sound quality, rated 4.5/5, at $49.99; the TANGZU Wan’er SG Studio Edition ranks #120, rated 4.4/5, at $49.99. The price gap is small enough that the sound-quality ranking should decide it.
The case for the Ooopusx OP24: Its six-driver hybrid scores 80.0 across 11 hobbyist measurements on squig.link, and sub-bass and bass both sit nearly 2 dB above target, giving electronic and hip hop tracks a full, rumbling low end. The catch: A 5.8 dB peak near 8.1 kHz can make cymbals and esses sound splashy on bright recordings.
Buy the Ooopusx OP24. It is rated higher for sound quality than the TANGZU Wan’er SG Studio Edition at the same price, which makes it the one to get unless you need something the other one does better.

Pros: Its six-driver hybrid scores 80.0 across 11 hobbyist measurements on squig.link, and sub-bass and bass both sit nearly 2 dB above target, giving electronic and hip hop tracks a full, rumbling low end. Treble from 6 to 10 kHz is lifted about 1.9 dB for crisp detail, a lively v-shaped balance. A second impedance mode (15 or 27 ohms) gives a tuning option, and 127 dB/Vrms sensitivity makes it easy to drive.
Cons: A 5.8 dB peak near 8.1 kHz can make cymbals and esses sound splashy on bright recordings. The 4.7 dB dip that follows near 10.2 kHz makes the top end uneven rather than smoothly extended.
