Brand new iphone earphones in the box with a recipet for 1 year guarantee -

Hi there I have a brand new pair of iphone earphones in the box with a recipet for 1 year guarantee , I brought them from the apple store as I thought my old headphones were broken , but when I tried them I still had the same problem , so it was my phone not my headphones. I brought them on 11/08/2012 so like 3 days ago , they have not been used at all.I bought them for 26 pounds and the receipt comes with it guarantee for 1 year.
