An adapting device for adapting a first portable media player to emulate selected mechanical and electrical characteristics of a second portable media player includes a housing having first and second connectors. A signal converter may be operatively connected to the first connector and the second connector for converting a first signal representing at least one command received over the second connector into a second signal representing the command to be transmitted over the first connector.
