Short answer: the AME Custom Mousa. Both are rated 3.3/5 for sound quality (#935 and #938 of 1291 in-ear headphones), and the AME Custom Mousa costs $4,500 against $5,130 for the Aroma Audio Jewel, with sound quality a draw, the lower price decides it.
The case for the AME Custom Mousa: About 4 dB more bass than the Harman target below 150 Hz, for listeners who want a fuller low end. The catch: An uneven response, 2.5 dB standard deviation from target.
Why pick the Aroma Audio Jewel: 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.
Buy the AME Custom Mousa. Both are rated the same for sound quality, and it costs $630 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.
