Abstract
A low-profile, retractable ear-bud system is adapted for attachment to a portable electronic device such as an MP3 music player. The system comprises a housing within which there is disposed wiring having a proximal end in electrical communication with the portable electronic device and a distal end terminating in a pair of ear-buds. The wiring is wound on a spring-biased spool disposed within the housing, the spool having at least a retracted position for storage and an extended position for use of the ear-buds. In the preferred embodiment, the wiring is wound on the spring-biased spool in a single pancake-style layer. The proximal end of the wiring is in electrical communication with the portable electronic device preferably through a multi-conductor slip ring.
