Abstract: An entertainment receiver system, especially adapted for use on a physical exercise apparatus, is used to combat boredom during exercise sessions. Physical stresses on the housing units are associated with connecting and disconnecting the headset jack of the user's headset into the jack plug on a traditional unit. These stresses can make the unit non-functional. As a solution, a movable headset jack plug is provided external to the housing. The jack plug can be comprised of a flexible cord or a rigid structure movably mounted to the frame by a joint such as a ball and socket. The movable jack plug can be cushioned by a coil spring with the flexible cord or a cushion in the joint of the rigid structure. The movable nature of the jack plug necessitates the user physically holding the plug while they insert their headset jack into the plug. By physically holding the plug and jack, the force applied to the headset jack is equal in magnitude to the reaction force provided by the hand of the user to the plug.
