Late to the show & this thread...
I was listening to the Interstellar blu-ray late one night through my Sennheiser 555 headphones, as not to wake the vast hordes of Chipmunks living under my bed, when they suddenly began crackling... the headphones, not the chipmunks...
Scared the hell out of me... and woke the Chipmunks... which it turns out was far worse than the crackling noise...
I hope I haven't ruined them... the headphones, not the chipmunks...
