I believe the author is speaking in relation to a snippet from an advice that was given by someone else in regards to approaching a woman with headphones on. Dan Bacon, the guy the author is responding to says it is okay to approach a women with headphones on to engage in conversation but the author think otherwise. According to the author, it is never acceptable to approach a woman with headphones on to start a conversation. Basically, most of the time if a woman has on headphones she is insinuating that she needs to be left alone.
