NW-S764BT

The NW-S764BT is the Bluetooth-headphone bundle version of the ninth-generation S Series Walkman. It marked the first built-in Bluetooth in the family. Featuring 8 GB storage for MP3, WMA, AAC, and WAV playback plus video and photo, it uses a 42-hour lithium-ion battery. WM-PORT, Clear Phase, Bluetooth, and bundled headphones were included.

This Walkman model reinforces the same idea as the NWZ model. Wireless is added carefully, without flattening the product into something generic. It still is a Walkman.
