These are great. I love them. There is so much customization of both fit and sound. Once or twice the bass has taken me by surprise. With my personalized configuration, its only present when it is supposed to be. They look and soind amazing. I will complain that after a couple of hours wearing them, they hurt my ears a little. The battery life could be improved, and I got them on sale at Amazon for $89.99. Keep an eye on them. They do go on sale. I love the purple ones, but I just cant pull off purple, so I got the white. Also, this is a very minor complaint, bit the case these go in is very smooth, and can slip right out of your hand.
