Sometimes bigger IS really better, especially when it comes to sound. The 500XL speakers are 500 times the size of the original ear bud headphone speakers! 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 PC’s USB port with thesupplied cord; or plug it into the wall with a generic power supply (not included).
