Abstract
A mobile device case includes a reel assembly, including a reel, a supporting plate, and a hub between the reel and the supporting plate. The hub includes a first cavity between the hub and the supporting plate for housing a spring, and a second cavity between the hub and the reel for housing a flat flexible cable (FFC). The spring is wound in a first direction, while the FFC is wound in a second direction. The FFC includes a first end for electrically coupling to a female jack connector of a device. A female connector is electrically coupled to a second end of the FFC for engaging a male jack connector of user-provided headphones. When the reel rotates in the first direction, the spring tightens and the FFC loosens. When the reel rotates in the second direction, the spring loosens and the FFC tightens.
