All "fanny" and "wang" jokes aside, the idea of social headphones is intriguing. Letting a friend in on my "outstanding" musical tastes without having to plug in one of my disgusting headphones seems so obvious that I am almost ashamed that the thought had never crossed my mind. Although simply including another 1/8 inch headphone jack shouldn't warrant a $170, unfortunately named and rather loudly designed set of cans. According to the commenter "messianicomplex" there are other options available like the Urbanears Plattan, which appear to be cheaper and are more modestly designed, although they probably lack the relevant sound quality.
