NW-S14K

The NW-S14K is a twelfth-generation S Series model with 8 GB storage, MP3/WMA/AAC/WAV support, 77-hour lithium-ion battery, Bluetooth, speaker output, video and photo playback, and Clear Phase. AptX was newly added to the series.

The speaker K version keeps that same late simplified S platform and gives it a more casual-use presentation. The important part is still the underlying shift: this is the S Series becoming more straightforward, more modest, and more practical as Sony's portable line narrows around fewer clearer identities.
