NW-WS623

The NW-WS623 is a W Series Network Walkman with 4 GB storage supporting MP3, AAC, and WMA playback. A lithium-ion battery delivers up to 8 hours of use with Bluetooth.

This unit kept the wearable W Series focus with added wireless capability. The WS623 is part of the next mature phase of Sony's sport Walkman branch, where the line had already proven its reason for existing and was now being refined as a durable, specialized platform. Sony was making the branch more livable, more flexible, and more believable as a long-term product family.
