Cans-celled.

Uggh.  The left side on my Sony headphones has gone dead.  I assume the cord has just been stepped on or run over by my chair wheels one too many times.   I doubt I can take the earpiece apart to get at the wires, so it looks like a new pair is in my future.  They were just a cheap 50 buck or whatever pair, but they've served me well as I sat in front of my computer listening to hours of music every day.  I'm not even sure how old they are, as I have no idea what year I bought them.
