It is not only fashionable and stylish, but it can also be used as a Mass Storage Device. The best thing about it is the fact that it is just about the size of a credit card, so it can easily be kept in a pocket.

Just to make an idea about it, I should tell you the player measures 85.5x54x4.5mm and weighs no more than 20 grams. It is compatible with Windows 98SE/ME/2000/XP, Linux or Mac OS, so there should be no problem at all.

When it doubles as a Mass Storage Device, all the data and info you need is going to be with you whenever you go and whatever you need.

It is powered by a built-in rechargeable battery. Not to mention it comes with an integrated 2GB of storage space, USB charge option, as well as sync cable, AC adapter and a pair of earphones, which can be replaced with your favorite ones.

And don't worry, in case you run out of battery, there is a built-in LED which lights when it runs out of juice. However, in case you want to purchase this type of MP3 player, you can do it directly from the manufacturing company's web store, for a starting price of about 42 bucks a pop.
