Abstract: The SonicDome is a ski hat containing internal headphone speakers. An internal connecting wire drops down from the hat. At the end of that wire is a stereo mini-plug that can connect to most portable listening and viewing devices (CD Walkmans, MP3 players, small TVs). By combining two widely used items—headphones and headgear, the SonicDome will allow the wearer to enjoy music, books on tape, television, etc., while partaking in outdoor activities in cold weather.

Abstract: The Hearmuff is double-sided felt material that covers your ears by wrapping the product around your head, covering your ears to keep them warm. It contains earphones, one for each ear that is surrounded within the earmuffs. It is adjusted by the Velcro at both ends and is used for entertainment while keeping the ears warm during cold weather.
