Urbanears Plattarn £50. LINK click
I have got them since a week. Previously i had Sony speakers. The difference is huge. great bass, built in microphone (hardly noticeable) with button(on off) (but You plug them into one mini jack).
-very short cable
-or they are a little bit too tight or maybe my head is that big...
+buy one get one at HMV
+very good materials
+ability to plug another headphones as they have a built in female mini jack.
