I could, but not yet. Obviously they sound amazing, but I am still playing with fit and have much more to play around with them. I do plan on doing a review though. Commenting on sound with details now is pointless as I have a bit of a cold. I will start commenting on sound characteristics when I am not sick and have had some alone time with them.
EDIT: By fit, obviously these are customs, but I mean getting them to be in my ear properly and consistently doing such quickly/easily.
EDIT 2: I should say though, I was using my Pico Slim at first, but decided to have a listen with the ZO2 instead. I really wanna save my impressions for my review of them and for informing Dale about my opinions. But this i couldn't hold back, bass monsters even on green, but the closer and closer it gets to red the more bass you get and nothing seems to be compromised in the process (this may be because i'm sick), completely and utterly bass bliss. Gonna stop making Dale's email go crazy, that's it for now.
