Overview

The Sony NWWS413LM is a self-contained wearable MP3 player that wraps around the back of your head, placing both the player and earbuds in a single cord-free unit. With waterproofing rated to 2 meters in salt and fresh water, plus sweat-resistant and dust-proof construction, it is purpose-built for swimmers, runners, and gym-goers who want music without carrying a phone. The ergonomic design and included adjustment loops help secure the fit across different head sizes and activity levels.

On the audio side, 4GB of onboard storage supports MP3, WMA, AAC, and Linear PCM files loaded via simple drag and drop from a Mac or Windows computer through the included USB dock. Up to 12 hours of playback means multi-day use between charges for most users, and a quick-charge feature gets you back up and running fast. The ambient sound function is a thoughtful safety addition, letting environmental noise pass through so you can hear traffic or conversation without pausing your music. Sony includes both regular and swim earbuds in the box, covering dry and wet use out of the gate.
