Hi, I bought the sure's off ebay for about £40 from germany. The are good and have a range of in ear rubbers to help you get the right size and feel, but my ear started ringing loudly after using them at a mid volume on my ipod. I then read in the instructions that because they are better quality you should listen at lower levels and if you get a ringing then stop using them... scared to use them now. But that could just be me after jamming in bands for many years in small loud rehearsal spaces.
They seem fairly weighty and fall out of my ears easily, and if you knock the cable it picks it up. They were rated highly but I'm not that fussed to be honest.
