Xperia T follows the CTIA standard (also used by Apple) while the previous phone like Xperia arc follows the OMTP standard. Note that this is only about headsets and not headphones. Headphones only uses two pins and there is only one standard.
So if these products doesn't have any mic there is only one standard and you can use them in any of our phones. But I suspect that you mean headsets so check if they follow the CTIA standard.
You should also check if these products uses a music controller, if yes they might use a different voltage other than what's compatible with Xperia T. In that case check with the manufacturer if any compatibility tests have been made.
