...as well they should, sort of. You are knocking the S0's for not sounding like the s5's in two posts now....but the S0's have nothing to do with the S5's, except maybe the cables. The S0's are half the price of the S5's and have an entirely different signature(as well they should, they aren't trying to be cheaper S5's, they are trying to be good quality $50.00 IEM's...which they are). Lot's of folks have chimed in here already testifying that the S0's are a great value, with good build quality and good sound, and some prefer the signature over that of the S5's. It doesn't make them any better or worse, just different. I like them both for entirely different reasons, and that's all that matters to me. I like choice, and low cost choice best of all
