They do when training indoors.

So I now remember that you live in the north east where winter may force indoors to get your miles in and headphones might help drown out the din and possible 'bad' music that they play in there.

But of the runners that pass into serious training I've never met anyone in running clubs or 'long slow run' groups that would use them. There is too much of a need to focus on your pace, spits and surroundings to have that distraction. In addition that distraction subtracts from the true essence of an outdoor run, the exception being when people first start running and they need the distraction because they really don't like being out there :)
