Unfortunately it is impossible without messy hardware modifications.
Sony used to use a headphone plug standard almost nobody used. Special headsets made by Sony would work, but the most popular ones (like iPhone headsets) wouldn't.
With the Xperia S and the other 2012 phones they reversed their decision and switched to the more popular standard. The good thing is you can use all iPhone-things with the Xperia S. Bad news is that older Sony Ericsson headsets don't work anymore.
All regular headphones/earbuds (without any buttons) will work fine however.
