How they did it is pretty obvious: simplicity. No video playback, no color screen, and nothing that would otherwise consume excessive amounts of battery life. On the player, you will find a crisp OLED display, FM tuner and about 2GB of storage. Nothing about the B153 stands out except the exceptional battery life. If you're looking for a simple (yet capable) player that will go potentially for weeks without a charge, this was made for you.
