Short answer: the Moondrop Solis 2. It ranks #48 of 1291 in-ear headphones by sound quality, rated 4.7/5, at $2,999; the Final Audio A10000 ranks #299, rated 4.2/5, at $2,999. The price gap is small enough that the sound-quality ranking should decide it.
The Moondrop Solis 2 is the better-sounding pick. The Solis 2 combines dynamic, balanced armature and electrostatic drivers, and the median of five hobbyist measurements on squig.link gives it a preference score of 82 with about 1.2 dB of unevenness. The catch: A 4.7 dB peak near 8.1 kHz can make cymbals and sibilants a touch hot, while the presence region dips about 3.5 dB near 5.9 kHz.
What the Final Audio A10000 does well: Bass, low mids and presence all sit within about 1 dB of target on the squig.link measurements, so the low end is full depth but uninflated and voices come through with natural tone. Watch for: A sharp 10.4 dB peak at 8.1 kHz lifts the 6 to 10 kHz band 4.8 dB over target, which can make cymbals, sibilants and hi hats sting at higher volume.
Buy the Moondrop Solis 2. It is rated higher for sound quality than the Final Audio A10000 at the same price, so it is the default pick unless a specific strength of the other one matters more to you.
