I have both of them coming. My ZSX are in the states. The C12 are still sitting in China. So I’ll have at least a week with my ZSX by the time my C12 arrive. I’ll give initial impressions hopefully within 24 hrs of having them in my hands. The cage match between the ZSX, C12 and V90 will be interesting. The new Tool album is waiting to give them all a good workout.
