An electronic device cover provides a protective cover for an electronic device and also extends and retracts a plurality of audio and data transfer modules at varying speeds and lengths. The electronic device cover is configured and shaped to receive myriad types and models of electronic devices. A proximal end of a communication cord extends from the electronic device cover to provide communication modules such as ear buds, or head phones to a user. A distal, shorter end of the same cord extends more slowly and at a slower speed from a different end of the electronic device cover to provide connections to the more proximal electronic device, power sources, and other electronic ports. The cords extend at different speeds and lengths due to a differential affect.
