I am having a very hard time using my iphone headphones outside these days in Chicago.  It gets pretty cold, and the plastic that they wrap the wires in freezes up almost instantly, making the cable stiff like a piece of solder.

So when you turn your head, the headphone wires don’t move and the ear buds pop out of your head.  Pretty poor design.

I guess it doesn’t get this cold in Silicon Valley, where Apple has it’s headquaters.
