rjaja's answer:
they are suppose to be worn in the cold weather,and they keep cold wind from blowing into your ear.cold wind that gets into your ears causes an ear infection,and they are painful.if you get a ear infection the following will happen:you can't yawn,(it wil hurt your ears),you will wake up in the middle of the night and your ears will stop hurting,(if it happens,make sure you rub under your ear in circles,).thats what earmuffs prevent.
