Abstract
A retractable cord for mobile phones or other wireless devices. The cord includes an ear piece having a speaker for delivering sound to a user and possibly having a microphone. The retractable cord can be contained within a separate unit with a connector for attachment to a connector on the mobile phone or other wireless device, such as a jack or other receptacle, or it can be contained internally within those devices. The cord can retract onto a spring-loaded spool, or via other retractable mechanisms, and be held at various extended positions with a stop mechanism that prevents retraction of the cord.
