Not sure if you can see clearly from this. Iphone4 isn't very up to date with its camera. Hahaha. The plug looks as though I've sandpapered it roughly and if you noticed, there's a small part that has already lost its top coating.
Ah... What I meant was the rubber part of the plug, not the 3.5mm jack itself. My bad, should have gone into specifics. I know it ain't gonna affect SQ but afterall when we buy something, we expect the product to look spanking new.Mine looks as though it's been abused for quite a while.
