If you're looking for the SHE3580 you can substitute with the SHE3590 or SHE3500. 99% sure that the 3590 is the same thing (even the mic'd 3595 that I own sound exactly the same). Less sure about the 3500, but it looks more well-built than the 3590.
The SHH3580 that I own have less bass than the SHE3580. That can be a good or bad thing depending on how much bass you like. They're the only pair I know of in the SHE3xx00 series that sounds significantly different from the SHE3580 and still I'd say the difference is not big.
i dont have those models in argentina, jsut the ones i posted
i read somewhere that the 3570 was the same as 3580, but i dont know.,
