Didnt you smell the burning?!
give me those old style cushioned earphones anyday,they are much nicer.I also have an old pair of red earmuffs(remember them ?!)my son used to wear them pretending to be a builder, Remember that film"theres something about mary" her brother wore them and wouldnt let anyone touch his ears...!
I burn thiings sometimes too...the other week I put an egg on to boil, came upstairs to the computer,forgot about it ,when I remembered and rushed down the water had all evaporated and the egg had exploded!
That burnt smell seems to linger around the house for ages afterwards.
