According to everyone in here who's compared the two: these have more bass.
Get 'em, homie.
I think everyone here has said that S680 has less bass than S500. S500 is more v-shaped.
Sony XB500! All the bass you need.
Just per curiosity, for which usage would it be?
According to some people in the US, this usually only happens if you buy more than one of the item, or if the total is over $350. I'm not sure how it works in other countries.
Can anyone confirm for US that they didn't get charged for customs tax, VAT, etc for amazon or other resellers?
