Short answer: the FlipEars Aegis. It ranks #997 of 1369 in-ear headphones by sound quality, rated 3.2/5, at $479; the Campfire Audio Chimera ranks #1042, rated 3.1/5, and costs $7,500, which makes this an easy call rather than a real tradeoff.
Why pick the FlipEars Aegis: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. The catch: Treble about 2 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Why pick the Campfire Audio Chimera: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. The catch: An uneven response, 2.7 dB standard deviation from target.
Buy the FlipEars Aegis. It is rated higher for sound quality than the Campfire Audio Chimera and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.
