NW-S775K

The NW-S775K is a tenth-generation S Series model with 16 GB storage, MP3/WMA/AAC/WAV support, 42-hour lithium-ion battery, speaker output, WM-PORT, video and photo playback, and Clear Phase. The body measured about 7 mm at its thickest.

The K version keeps that same S775 formula and wraps it in the same accessory-friendly retail logic as the surrounding variants. Sony had finally built an S Series that no longer felt like it was searching for relevance every generation.
