I'm jumping to the wagon guys. However, my Piston Hybrid will arrive around next year. T-T Since there is no official supplier yet in my country, I bought it through some group buy in local forum. I heard piston 2 before and piston 3, so far my opinion regarding them is good compared to the price. Great bass, OK mid, but little bit lacking high. But I can't complain when I know their price. I hope this piston hybrid will be better.
