The main thing that we are going to do is take apart some headphones and and put them in a beanie(I'm useing a beanie with ear flaps). The stuff that you are going to need is: a two layer beanie(perfreably with ear flap) ,headphone speakers with a foot of wire connected to each one, a 3.5 mm inline phone jack, a 3.5 steareo male to male cable, a sewing needle with thread and a soldering iron with solder. i did all the work on this project at the TechShop in San Jose. www.techshop.ws

Step 1: Soldering the Wires

Before we start soldering stuff we need to trim and prep the wires. Cut the wires and expose the two smaller wires inside the plactic coading. The smaller wires will be two different colors, you can identify which smaller wire is positive or negitive by looking at the back of the speaker. the smaller wires are insulated so you will need to burn the inslation off with either the soldering iron or a lighter. be sure to put the two main wires through the phone jack cover and tie a knot in the wires to keep the wires from pulling on the soldering connections BEFORE you begin to solder. After that you need to group the negitive wires together and keep the two positive seprated.  Solder the the two negitive wires to the largest connection and separately solder the positve wires to the two smaller connections. When the soldered connections are cooled put the phone jack cover over the soldered connectons. plug one end of the 3.5 mm steareo male to male cable into the headphone jack and the other end into a phone with music and test the speakers. If all is well you can move on the next step.
