Short answer: the FiiO FA7S, though neither ranks well in its class. It ranks #433 of 450 in-ear headphones by sound quality, rated 1.9/5, at $947.19. The Campfire Audio Dorado 2020 ranks #446, rated 1.3/5, at $699, $248.19 cheaper, a saving that is not big enough to make up the sound-quality gap. Both are rated below 3.0/5 among the 450 in-ear headphones, so if sound quality matters, consider the ThieAudio Monarch MKIII instead, ranked #1 at $999.
The FiiO FA7S is the better-sounding choice. Six balanced armature drivers per side at 18 ohms and 111 dB/mW make it very easy to drive from a phone or a small dongle. Watch for: Crinacle’s measurement yields a preference score of just 48 with a 3.7 dB spread around the target, a poor tonal result at a flagship price.
What the Campfire Audio Dorado 2020 does well: Bass runs 6.6 dB above the Harman target from 60 to 200 Hz and sub-bass holds within 6 dB of target down to 20 Hz, so bass lovers get a big, rumbling low end. The catch: In oratory1990’s measurement a 7.5 dB dip near 3.8 kHz and a presence region 4.5 dB below target push vocals and guitars back behind the bass, for a preference score of only 40.
Buy the FiiO FA7S. It is rated higher for sound quality, and the $248.19 saving on the Campfire Audio Dorado 2020 is not enough to make up the difference.

FiiO FA7S: $947.19 Amazon eBay
Pros: Six balanced armature drivers per side at 18 ohms and 111 dB/mW make it very easy to drive from a phone or a small dongle. At 8.4 g per earbud it is light for a multi-driver in-ear.
Cons: Crinacle’s measurement yields a preference score of just 48 with a 3.7 dB spread around the target, a poor tonal result at a flagship price. The Fidue A91 Sirius rates higher at a similar cost, and there is no inline microphone for calls.

Campfire Audio Dorado 2020: $699.00 Amazon eBay
Pros: Bass runs 6.6 dB above the Harman target from 60 to 200 Hz and sub-bass holds within 6 dB of target down to 20 Hz, so bass lovers get a big, rumbling low end. The hybrid layout pairs a 10 mm dynamic driver with a balanced armature, and it rates above the Final Audio F3100 and the Westone Pro X50.
Cons: In oratory1990’s measurement a 7.5 dB dip near 3.8 kHz and a presence region 4.5 dB below target push vocals and guitars back behind the bass, for a preference score of only 40. The 94 dB sensitivity is low for an in-ear, so it needs more volume than most from a phone. The Audio-Technica ATH-E70 and the Mackie MP-360 both rate higher and cost less.
