I just bought these at the weekend. Beats by Dr Dre they are called. I was going to purchase a pair of the Quiet Comfort 3's from the apple store but after seeing these in the store and trying them both out I decided to go with these as the sound just seemed so much better. I have only owned cheap £20 headphones in the past so these just blew me away. The noise cancelling is great as well as I use the train a lot for going to uni. And although they are probably overpriced, I'm still very pleased with them. Very sexy as well.
