Upon connecting the shuffle to a computer, we learned that the voice-over feature must first be downloaded via iTunes.

Interestingly enough, normal headphones can still be used to listen to music. The only drawback: without Apple's proprietary headphone playback control, you will not be able to change songs or adjust the volume.

The headphone playback control offers two buttons for volume control and a center button for playback control. The center button can be clicked once to play, twice for the next track, and three times for the previous track.
