Geeky Winter trend I love: cute cold-weather accessories that double as headphones. Here's the latest offering for protection from the cold and great sound. The Sound Disk Beanie ($60) is a comfortable knit hat with ultra-thin disk speakers inside. The hat/headphone combo is compatible with any MP3 player.

It comes in three colors: neutral black or beige, or a bright, sunny yellow. Disk shaped speakers slip into specially-shaped pockets in the hat; simply remove them for cleaning. Stay warm while listening to all of your favorite music, wherever you are!
