Short answer: the KZ EDA Balanced. It ranks #427 of 1291 in-ear headphones by sound quality, rated 4.0/5, at $16.99; the TRN MT4 Pro ranks #611, rated 3.8/5, at $16.99. The price gap is small enough that the sound-quality ranking should decide it.
What the KZ EDA Balanced does well: A 7 single dynamic IEM that measures well (score 74 across seven measurements), with bass on target down to 20 Hz. Watch for: The listing sells three tunings (Balanced, Bass and Hi-Res), so pick the silver Balanced version this rating covers.
What the TRN MT4 Pro does well: A broadly balanced tuning with a preference score of 71 against the Harman target. The catch: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the KZ EDA Balanced. It is rated higher for sound quality than the TRN MT4 Pro at the same price, which makes it the one to get unless you need something the other one does better.

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.
