Those are some shallow and some honestly awful reasons to pick on one's choice of headphones and the people who buy them considering it's not your money being spent buying a pair of Beats headphones. It's theirs. They worked for it and earned it. I don't feel inclined to explain my financial decisions to random joes on the internet either.
And maybe they do sound great to that wearer. You don't know. What sounds good enough for them might not be great sound to you. That's perfectly fine. Maybe they did buy them for how they look. Why make that your business? Why do you even care that that's why someone bought the headphones? I go back to my earlier position: it's not your money being spent. It's theirs. Taking people to task for subjective things like this seems like a very strange thing to lord over people for IMO.
