Insulators and Conductors

One conductor I came in contact with today was gold. Now it seems a little odd for me to be coming in contact with gold on a regular basis, but the expensive set of gaming headphones I own have a golden tip around the part you plug it in. The rest, inside of the protecting rubber (insulator) layer is probably copper, aluminum, or some sort of other light and bendable metal conductor.

Since I feel like it's cheating to have one example for both insulator and conductor I'll mention another insulator... My computer case is an insulator because it protects the inside from getting a static shock. This was an important factor in deciding which case I got because the floor in my room is carpet, and my house is full of static, especially in the winter.
