Short answer: the Moondrop Lan. It ranks #58 of 450 in-ear headphones by sound quality, rated 4.6/5, at $45.99; the Ooopusx OP24 ranks #68, rated 4.5/5, and costs $49.99, which makes this an easy call rather than a real tradeoff.
The case for the Moondrop Lan: A median of 32 squig.link measurements gives it a preference score of 80.4 with only 1.48 dB of deviation, an unusually tidy response for a budget single dynamic driver. The catch: A 5.4 dB dip around 10 kHz and a presence band about 2 dB low take some sparkle and edge off cymbals and strings.
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. Watch for: A 5.8 dB peak near 8.1 kHz can make cymbals and esses sound splashy on bright recordings.
Buy the Moondrop Lan. It is rated higher for sound quality than the Ooopusx OP24 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Headphones In Full
Moondrop Lan: $45.99 Amazon eBay
Pros: A median of 32 squig.link measurements gives it a preference score of 80.4 with only 1.48 dB of deviation, an unusually tidy response for a budget single dynamic driver. Bass stays within 3 dB of target into the deepest octave and the midrange tracks the target almost exactly, so voices sound natural. At 120 dB/Vrms it reaches loud levels from any phone or cheap dongle.
Cons: A 5.4 dB dip around 10 kHz and a presence band about 2 dB low take some sparkle and edge off cymbals and strings. Sub-bass sits nearly 3 dB under target, so electronic music has less rumble than bassier sets. The KBEAR KB01 carries the same rating for less money.

Ooopusx OP24: $49.99 Amazon eBay
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.
