Just plug the apple brick in one of the outlets. As you can see, Im a big fan of these shoes. They are cute but my foot felt weirdly wobbly inside them (I do have quite narrow feet). If using for like an audio book which I do at night or to listen to sleep aid sounds battery lasts like 10 hours or so. Pair is so light its incredible and they charge up super fast. Pimple Popper" would call a "buffalo hump," though not as large as some mine is still big enough that it pushes the straps up out of the neck of my clothing in the back about a half inch so if people bothered to look theyd see it. Please avoid and go for something that is not guaranteed to fail on you. Now to address a few reviews I read before buying them. Couldn?t be happier with the Ortofons. Please beware.
