NOVELTY - The system (100) has an electrical cable (110) selectively coupled to an electronic device for transmitting electrical signals to and from the electronic device. Two electrical conductors are electrically coupled to the electrical cable. A repositionable control device (121) is selectively coupled to the electrical conductors of the electrical cable to control functions associated with the electronic device. The control device includes a button (124a) to selectably control functions associated with a microphone. An attachment mechanism couples the control device to the electrical cable.    USE - Repositionable control system for controlling a function e.g. mute function, volume control function, track selection function, pause function, voice command function such as voice command on/off function, answer function and track search function, of an electronic device e.g. mobile telephone such as smart-phone, and media player (all claimed). Can also be used for controlling a unmute function, call reject function, call hold function, call start/end function, power on/off function, play function and select function of a portable audio device, personal data assistant (PDA), personal computer and an exercise machine.    ADVANTAGE - The electrical cable can be designed to enable operational coupling at any number of positions, so that a user of the control device can be provided with a convenient and easily accessible control unit without having in-convenience of being struck by a control unit housing while engaged in an exercise activity.    DETAILED DESCRIPTION - The electrical cable is a stand-alone or detachable cable. The microphone is selected from a group consisting of a micro electrical-mechanical system (MEMS) microphone, condenser microphone and a dynamic microphone.
