I have a pair of Sennheiser headphones myself. They retailed for $299 back in the day, you can get them for like, $170 on amazon.com, best headphone I've heard. Granted there's way more expensive models and other brands as well that are just as good or better. But, man, at $170 they're PHENOMENAL! There would be nothing wrong with Beats if they sold them for $50 bucks. But, at $300+ dollars for some of their "top end" models, it's just ridiculous. All because they're the in thing. You can get shoes that are ten times better than Nike. But, kids want to have that Nike logo on their shoe.
But, hey, Kudos to Beats and Bose for making a buck! That's what the world is all about.
