If you ever wondered what would happen if you took a pair of iPod earbuds and magnified them by 500 times, the fine people over at Think Geek has eliminated the guess work for you.
From the site:

Sometimes bigger IS really better, especially when it comes to sound.
That’s why we took a puny pair of earbuds, put them in Fred”s highly
technical Way Big machine, and created 500XL – it’s 500 times the size
of the original! How great will these look on your desktop alongside your
mp3 player or PC? 500XL includes a built-in amp and 3-way power -
it runs on batteries; you can connect it to your PCs USB port with the
supplied cord; or plug it into the wall with a generic power supply
(not included). The stand-up, peggable clamshell packaging really
makes a statement.
