Techniques for providing eyewear with electrical components are disclosed. The electrical components can provide electrical technology to eyewear without having to substantially compromise aesthetic design principles of the eyewear. The electrical components can be partially or completely internal to eyewear, such as within an extended endpiece or a removable temple (or temple part). The electrical components can also be attached to the eyewear as an after-market enhancement. The electrical components can operate independently or together with other electrical components provided elsewhere. Apparatus for presenting after-market electrical components are also disclosed.
