This super-thin USB Flash Card MP3 player from Brando is about the size of a credit card or just slightly larger at 85.5 x 54 x 4.5 mm and can house 2GB of listening media. It can also work as mass storage (if you call 2GB mass storage anymore) by connecting via USB to your computer.
The device can play MP3 or WMA files and has buttons that are flush with the frame that control navigating the songs. It also has a red LED light that lets you know the internal battery is charged and the player is on. You can even make a special request to have your own graphics put on the player, making it a nice “business card” MP3 player to give away to clients and customers.
If you’re looking for something thin and you’re not concerned about brand name or bells & whistles this is one you might want to check out. It only comes in the 2GB capacity and it retails from Brando for $42, which doesn’t look too bad for what you’re getting.
