Well, I just got a chance to listen to my Atrio M5 MG7 IEM's and omg...
I tested out both my ZO2 and E11 and again, the E11 is much cleaner all around, even in the bass area.
With all my cans, the E11 wins with a landslide. On a good note for the ZO2, there's no distortion through my MG7.
Again, I'm not knocking on the ZO2, I'm a hugeeee basshead that prefers clean audiophile bass.
Lol. Good luck. I'm interested in the A10 vs. E11. I couldn't be happier with the sound from my E11.
