Short answer: the TOZO Golden X1. It ranks #775 of 1291 in-ear headphones by sound quality, rated 3.6/5, at $149.99; the QoA Gimlet ranks #834, rated 3.5/5, and costs $154.04, so there is little reason to consider the other one.
Why pick the TOZO Golden X1: A broadly balanced tuning with a preference score of 68 against the Harman target. The tradeoff: An uneven response, 2.1 dB standard deviation from target.
Why pick the QoA Gimlet: A single dynamic IEM with a 10mm LCP diaphragm. The catch: A 2.41 dB spread from the target shows peaks and dips that better tuned sets avoid.
Buy the TOZO Golden X1. It is rated higher for sound quality than the QoA Gimlet and costs less, 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.
