Re: is this bad?
Yeah, my brother sometimes thinks I'm sychic, as when I'm wearing headphones, I can hear them buzzing before the phone rings.
Its not dangerous though no I wouldn't think, as the speaker cones are just reacting with sound in the same way they would with a real electrical audio signal from the source.
Its something to do with the magnetic coils I believe, and them making the cones move.
