Short answer: the HIFIMAN RE2000. It ranks #685 of 1291 in-ear headphones by sound quality, rated 3.6/5, at $799; the Campfire Audio Supermoon ranks #835, rated 3.5/5, and costs $899, which makes this an easy call rather than a real tradeoff.
The case for the HIFIMAN RE2000: Crinacle’s measurement gives a Harman preference score of 69 with a deviation of 2.63 dB, a respectable match to the target most listeners prefer. The tradeoff: A score of 69 is only middling for a flagship in-ear, and a response that deviates from the target by 2.63 dB leaves audible coloration.
Why pick the Campfire Audio Supermoon: A 14mm planar magnetic IEM with full sub-bass to 20 Hz and a 67 Harman score across three measurements. Watch for: Expensive for its rating, and a low 94 dB sensitivity needs more volume.
Buy the HIFIMAN RE2000. It is rated higher for sound quality than the Campfire Audio Supermoon and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
