It is very cool here in Philadelphia, which is how it should be in the winter. If you are in a wintry place at the moment (or plan to be) and you enjoy keeping your ears warm and listening to your iPod then 180s has the product for you.
Behold the 180s Tec Stretch ear protectors (don't call them ear muffs)/headphones. The cord is removable so you can protect your ear when not listening to your iPod. They can be found online for around $20, and would make a lovely gift.
