I've had my Miracles for two days now and I'm sad to admit that I don't like it. I was hoping it was going to be a neutral IEM like many people claim.
Here are my observations:
- Extremely emphasized 6.5KHz region which causes unbearably harsh treble.
- Lacking in upper treble (>8KHz)
- Everything under 1KHz is boosted by 5dB resulting in overemphasized bass and lower mids
- Recessed 2KHz to 4KHz region resulting in under-emphasized female vocals. Female vocals sound distant and recessed.
I can mostly fix these issues with EQ but I feel that the bass and lower mid decay is still too long (which can't be fixed with EQ).

This information should be helpful for people like me who strive for neutrality. Guess I'll have to keep looking for a more neutral IEM.
