A common axis, multi-pole connector assembly provides improved connectivity with electronic devices having mating receptacles of differing form factors. In one aspect, the connector includes assembly includes a single pin, hollow plug body, one or more conductive lines extending within the plug body, and a sleeve configured for sliding reception over the plug body. The plug body is formed with one or more discrete conductive contacts with which the one or more conductive lines are electrically coupled. The sleeve, which may be either formed as an insulative body or formed with one or more discrete conductive contacts, has an axial length that is less than the axial length of the plug body so that when the sleeve is installed on the plug body, a portion of the plug body extends out from beneath the sleeve.
