it is not working

Bought mune for £ 14:99 from RMobile store in Lancaster UK 14/10/2011. Quality headset comfy and loud too! Can accept calls by pressing the button on the side and redial by pressing the same button too. Can use the over ear plastic curve thing or u can take it off and just wedge it in. I like this too coz the charger is the same as my phone samsung galaxy s (micro usb) so can use one car chrger for both.****
