A suggestion: Never buy headphones on amazon unless it's amazon.com. Their only good deals are for US customers.
I bought my AD700s from amazon.co.uk and the price at the time was £87 which was very little compared to the other places that sold them.
I am hoping not to buy my next pair of headphones from amazon but from a local store. There is one store quite close to me that sells the K550 and they say that the lowest price is guaranteed. They are £130 on amazon.co.uk which I think looks like great value.
