DESC: The NW-E505BLUE is both an MP3 player and a radio. It has 512MB of storage capacity, letting you load up with 345 songs of your choice. But, it also comes with an FM tuner, so you can scan the dial when you need a change of pace. All this, and it's about the size of a pack of gum. The NW-E505BLUE also features insane battery life: up to 50 hours of playback on one full charge. And, If you're down to your last bar, just quick charge it. A three minute charge gives you three hours of battery life.
