Abstract: A case for holding an audio device having a female audio jack. The case has a removable cover including a male audio jack for electronically connecting the cover to the female audio jack of the audio device. The cartridge includes a spool and houses an ear bud cable. The ear bud cable has a first end with at least one ear bud, and a second end attached to the spool. The cartridge has a rotatable spool for selectively retracting and dispensing the ear bud cable. The spool electronically connects with the male audio jack to enable audio communication between the audio device and the ear bud. In one embodiment, the spool electronically connects with the male audio jack via a jumper wire. In another embodiment, the spool electronically connects with the male audio jack via an electrical contact pad integrated into the case.

Abstract: A cartridge for managing ear bud cables includes a housing, a hub, a spool with a moveable audio contact and an ear bud cable. The housing has an input jack that is electronically connectable to an audio-source. The hub defines a stationary contact surface electrically connected with the input jack. The ear bud cable wraps at least partially around the spool, the ear bud cable has a first end and a second end, the first end being electrically connected with the moveable audio contact of the spool and the second end being electrically connected with at least one ear bud. Rotation of the spool selectively retracts and dispenses the ear bud cables while enabling continuous audio communication between the at least one ear bud and the audio source.
