Short answer: the Vision Ears Phonix. Both are rated 3.3/5 for sound quality (#913 and #935 of 1291 in-ear headphones), and the Vision Ears Phonix costs $4,200 against $4,500 for the AME Custom Mousa, and with sound quality even, the cheaper one is the better buy.
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. Watch for: An uneven response, 2.5 dB standard deviation from target.
The case for the Vision Ears Phonix: Lower mids sit within about 0.6 dB of target, keeping voices and guitars natural. The tradeoff: 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 $300 less than the AME Custom Mousa.

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.
