earspray 

The noise emanating from the headphones of an iPod.

I could not avoid all the earspray on the subway.

ear spray 

overflow sounds from someone listening to their ipod too loud,
possibly first coined by an npr editorial.

sitting on the train for four hours with ear spray on me from the raging 15 year old brittany fan, what fun.
