I was sitting on PC just now with headphones plugged in, moved my knee and headphones snapped - like the long wire snapped out of the small bit at the end where you plug it into the PC... It didnt really hurt in fact I think it only brushed my finger but I started panicing that I might have received an electric shock - is this possible, considering headphones are full of wires? I thought since the laptop wasnt plugged in then I'm maybe at less risk? It happened fifteen mins ago and I feel OK, apart from tired and a bit tingly in that arm (but that only came on since panicing) and chest pain (again, only came on with anxiety) and a headache... Just want to be sure I'm OK before I try to get some sleep? I now I'm a bit daft as I chew on my ipod headphones all the time, they always have wires exposed so surely its the same principle but I just can't shrug it off?
