Unlike most water-resistant MP3 players, the new Sony Walkman W250 is cord free. The device, which has a player with 1.68GB of storage built into the headset, can survive a rain-soaked run or a rinse in the sink. It has an adjustable band that wraps around the back of the head and curves over the ears. It comes with earbuds in three sizes. You can shuffle songs, move forward or backward by turning a dial on the earpiece, and scan selections by playing only the main melodies. Three minutes of charging gives you enough juice to play 90 minutes of music; a full 90-minute charge lasts 11 hours.
