I bought these headphones there two weeks and I am quite satisfied. By cons I think you can find better value for money. I'm no expert but I do not feel much difference with my creative ep-630, which are much cheaper. by cons for the price it was a beautiful packaging, a good choice of connectors (3 single sizes and 3 sizes biflanges). The carrying case and also a good thing but it is a bit small to put the headphones and extension cord.
