The blue Sony Sports Walkman NW-WS413 4GB Digital Music Player is designed for active users. This headset features a unique ergonomic design that fits comfortably around your head and frees you from being tethered to another media player. It's equipped with 4GB of internal flash memory and supports MP3, WMA, AAC-LC, and LPCM audio files, so you'll have plenty of music to score your workout. To accommodate all active users, the NW-WS413 was designed to be water and dustproof, and to operate in extreme temperatures. Supporting its waterproof design, the NW-WS413 comes with a set of swimming earbuds you can use when you're in the pool.

The Walkman's built-in rechargeable battery provides up to 12 hours of continuous audio playback on only 90 minutes of charge. Plus, it supports drag-and-drop media file transfers from compatible Mac or Windows computers. A USB cable for data transfer and charging is included.

The compact design of the NW-WS413 provides a secure, comfortable, head-hugging fit, ensuring your Walkman stays in place no matter what.

With Ambient Sound Mode you can still hear a degree of external sound so you can talk to a friend or trainer while still enjoying your music.

The NW-WS413 comes with two sets of earbuds: a standard pair and another designed for swimming, which features a thin film over the hole to prevent water from entering the headset.

Waterproof and dustproof to IP65/IP68 specifications, the NW-WS410 will work when submerged in water to a depth of 6.6' for up to 30 minutes—even in salt water. The swimming earbuds must be used for the waterproof design to function correctly.

The NW-WS413 is waterproof up to 6.6' and features a sealed design that protects it from sand, dust, and grit. It can even handle extreme temperatures, capable of operating in temperatures ranging from 23 to 113°F (-5 to 45°C).
