Short answer: the Vision Ears Phonix. Both are rated 3.3/5 for sound quality (#913 and #938 of 1291 in-ear headphones), and the Vision Ears Phonix costs $4,200 against $5,130 for the Aroma Audio Jewel, with sound quality a draw, the lower price decides it.
What the Aroma Audio Jewel 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. Watch for: Treble about 5 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
What the Vision Ears Phonix does well: Lower mids sit within about 0.6 dB of target, keeping voices and guitars natural. Watch for: Presence sits about 3.5 dB low with a 4.2 dB dip near 5.8 kHz, so vocals and instruments lose some bite.
Buy the Vision Ears Phonix. Both are rated the same for sound quality, and it costs $930 less than the Aroma Audio Jewel.

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.
