I wear them upside down and I don't have the bumping problem that shigzeo mentions, you can also use a clip that comes with handsfree headphone sets it works nicely.
Here are pics wearing it normally and using the reverse mod:


Basically with the reverse mod they don't stick out at all, they're very VERY comfortable and I don't have any problem with the wires.you can also chose not to wear them over the ears with the reverse mod, but Id recommend over the ears.
