This is a pen, but not just a pen. The pen, with length of 148mm and diameter of 18mm, does play music too! The upper part of the pen is actually an MP3 player with 512MB of memory. It does have everything of a common digital audio player, except a display screen. Other than audio playback, it also has a built-in FM tuner and voice recording function. It can plays up to 7 hours continously once fully charged.

But wait, you gotta pay $48 for this pen!
