The Rock Star Headphones require you to hack into an existing set of headphones and incorporate it into a new design. The Rock Star will also have two square LEDs sewn onto the exterior of the earwarmers. The LEDs have both an aesthetic function and a practical, safety function: making the wearer visible for jogging or biking at night. The circuit incorporates a soft switch made from conductive hook and loop, so the LEDs turn on only when the headphones are worn.
