NW-S315K

The NW-S315K is a thirteenth-generation S Series model with 16 GB storage supporting MP3, WMA, AAC, and WAV files. It uses a 77-hour lithium-ion battery with speaker output, photo playback, and Clear Phase.

The speaker K version completed the thirteenth-generation S range. It keeps that same late simplified S platform and extends it into a more casual-use presentation.
