Short answer: the TRN Conch. Both are rated 4.4/5 for sound quality (#96 and #98 of 450 in-ear headphones), and the TRN Conch costs $29.99 against $34.99 for the Ooopusx OP22, so with nothing between them on sound quality, price settles it.
The case for the Ooopusx OP22: Twelve hobbyist measurements on squig.link give the OP22 a preference score of 78.9, and every band from 60 Hz to 16 kHz sits within about 1.3 dB of target. The tradeoff: Sub-bass falls about 2.3 dB short at 30 Hz, so deep synth bass has less rumble than the bassier KBEAR KB02.
What the TRN Conch does well: Fifteen hobbyist measurements on squig.link give the Conch a preference score of 79.0, a strong result for one of the cheapest in-ears around. The catch: Air above 10 kHz sits about 5.8 dB above target with a 6.7 dB peak near 8.1 kHz, so it can sound sharp and sibilant on bright recordings.
Buy the TRN Conch. Both are rated the same for sound quality, and it costs $5 less than the Ooopusx OP22.

The Two Headphones In Full
Ooopusx OP22: $34.99 Amazon eBay
Pros: Twelve hobbyist measurements on squig.link give the OP22 a preference score of 78.9, and every band from 60 Hz to 16 kHz sits within about 1.3 dB of target. That makes it one of the tamer budget hybrids, with treble that never jumps more than 3.8 dB and no harsh spikes. Its 124 dB SPL/V sensitivity means a phone drives it to loud levels easily.
Cons: Sub-bass falls about 2.3 dB short at 30 Hz, so deep synth bass has less rumble than the bassier KBEAR KB02. A 3.5 dB dip near 10.2 kHz trims some sparkle and air from cymbals, and slightly thick low mids can make vocals sound a touch dull.

TRN Conch: $29.99 Amazon eBay
Pros: Fifteen hobbyist measurements on squig.link give the Conch a preference score of 79.0, a strong result for one of the cheapest in-ears around. Bass runs 2.1 dB above target with sub-bass holding on target to 20 Hz, giving music warm weight for V-shaped tastes. Its 114 dB sensitivity and 30 ohm impedance make it simple to drive from a phone.
Cons: Air above 10 kHz sits about 5.8 dB above target with a 6.7 dB peak near 8.1 kHz, so it can sound sharp and sibilant on bright recordings. The presence band 2 dB below target recesses vocals a little, and the KBEAR KB01 earns a higher rating at a similar price.
