Short answer: the DUNU SA6 MK2. Both are rated 3.1/5 for sound quality (#1027 and #1042 of 1369 in-ear headphones), and the DUNU SA6 MK2 costs $559 against $7,500 for the Campfire Audio Chimera, so with nothing between them on sound quality, price settles it.
What the Campfire Audio Chimera does well: 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.
The case for the DUNU SA6 MK2: Bass sits close to target and holds down to 20 Hz, so low end sounds full without bloat. The catch: Presence sits about 6.8 dB low with an 8.6 dB dip near 5.6 kHz, so vocals and instruments lose some bite.
Buy the DUNU SA6 MK2. Both are rated the same for sound quality, and it costs $6,941 less than the Campfire Audio Chimera.

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.
