Short answer: the Etymotic ER2XR. It ranks #469 of 1291 in-ear headphones by sound quality, rated 3.9/5, at $149.99; the EarAcoustic OSHUN-LTD ranks #597, rated 3.8/5, and costs $152.91, so there is little reason to consider the other one.
What the Etymotic ER2XR does well: Bass and midrange track the target closely in oratory1990’s measurement, with sub-bass only about 3 dB shy and a smooth 2.3 dB deviation overall, earning a preference score of 73. The catch: Treble is muted, about 4 to 6 dB under target from 3 to 10 kHz with a 12 dB dip near 11.9 kHz, so cymbals and the sense of air are subdued.
What the EarAcoustic OSHUN-LTD does well: A single dynamic IEM with an 8.3mm dual magnet, dual cavity driver. The catch: Its score rests on three measurements.
Buy the Etymotic ER2XR. It is rated higher for sound quality than the EarAcoustic OSHUN-LTD and costs less, so only choose the other one for a particular feature it 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.
