The biggest and most sorriest example of social bias, slap a popular artists' name on a headphone no one has ever heard of before, and there you have it, the "best pair of headphones in the world."
Sadly enough, I'm seeing more and more Soul headphones around too.
Out of curiosity, I've asked several beats owners if they've ever heard of Sennheiser, and of course they all said no. In my opinion, the good brands need to step it up a bit and do some better marketing, because this is simply getting ridiculous.
And look at this, Soul headphones with Usain Bolt on it.
