I'm brand new to this sort of thing but these look like the coolest CIEMs ever. The custom AS-1 on the product page is visually the coolest thing ever but of course that's not what you get. But what I DO think is cool is the ambient port. It might be just me but with my previous set of IEMs (Turbines) I found occlusion to be a huge problem. I would have to wiggle around the tip in my ear for a bit to equalize the pressure, and I can't imagine that was good for my ear at all. But my turbines just broke and are not under warranty, which is why I came here.
I like that metal plate on the custom AS-1. Even if Aurisonics could add a simple brushed aluminum plate with an etching that would be fantastic!
