Short answer: the TRN MT1 Pro. It ranks #324 of 1291 in-ear headphones by sound quality, rated 4.1/5, at $18.99; the CVJ Konoka ranks #420, rated 4.0/5, at $17.85. The price gap is small enough that the sound-quality ranking should decide it.
What the TRN MT1 Pro does well: The median of 3 hobbyist measurements gives it a very good Harman preference score of 75 with a 1.87 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. The catch: Its 1.87 dB spread is less even than the best measured sets.
The case for the CVJ Konoka: The median of 10 hobbyist measurements gives it a solid Harman preference score of 74 with a 2.17 dB spread. The catch: A 5.3 dB peak near 2.0 kHz can make cymbals and sibilance sound sharp.
Buy the TRN MT1 Pro. It is rated higher for sound quality, and saving $1.14 with the CVJ Konoka does not make up for the sound-quality 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.
