Short answer: the Kinera Celest Wyvern Pro. It ranks #136 of 450 in-ear headphones by sound quality, rated 4.3/5, at $18.04; the Moondrop Quarks ranks #183, rated 4.2/5, at $17.99. The price gap is small enough that the sound-quality ranking should decide it.
Why pick the Moondrop Quarks: A preference score of 76 from a very inexpensive wired in-ear is hard to beat, and it is rated above the KZ ZSN Pro X and the CCA CRA. Watch for: A 4 dB peak near 2.9 kHz can make female vocals and snare hits sound forward or slightly shouty at higher volumes.
Buy the Kinera Celest Wyvern Pro. It is rated higher for sound quality, and the $0.05 saving on the Moondrop Quarks is not enough to make up the difference.

Moondrop Quarks: $17.99 Amazon eBay
Pros: A preference score of 76 from a very inexpensive wired in-ear is hard to beat, and it is rated above the KZ ZSN Pro X and the CCA CRA. Bass from 60 to 200 Hz is lifted about 2.2 dB over target and the low mids about 1.6 dB, giving a warm, full sound that fits warm and bass leaning tastes. At 16 ohms and 116 dB sensitivity it plays loud straight from a phone.
Cons: A 4 dB peak near 2.9 kHz can make female vocals and snare hits sound forward or slightly shouty at higher volumes. Air above 10 kHz is about 2.5 dB low and there is a 5.4 dB dip near 11.9 kHz, so the top end sounds less open and airy. Sub-bass under 60 Hz is about 1.8 dB below target, so the deepest notes lack a little rumble.
