This version of the iPod shuffle Generation 2 was updated to include five colors: silver (original), orange, green, blue, and pink. Also, this revision switch from the old-style “cap” earbuds to the current, more streamlined design. The case of this iPod shuffle features a clip that allows you to easily attach it to clothing.
This iPod shuffle’s design greatly differs from the original iPod shuffle that looked and functioned similarly to a flash drive. To charge this iPod shuffle and load it with up to 240 songs, it sits in a very small USB base with a protruding 3.5mm jack that uses the audio jack to transfer data and charging power.
The iPod shuffle is the only iPod with no display.
