NW-WS615

The NW-WS615 is a W Series Network Walkman offering 16 GB storage for MP3, AAC, and WMA playback. A lithium-ion battery supplied up to 8 hours of use with Bluetooth, NFC, and SongPal support.

This player is part of the point when Sony's wearable sport Walkman line had fully matured into something much more serious than a quirky side branch. Earlier W and WS models had already experimented with integrating the player into the act of wearing, running, and training, but by then the line feels much more fully developed as a branch with its own rules and its own audience. The device becomes less of a carries object and more of a piece of activity hardware.
