NW-E083K

The NW-E083K is a thirteenth-generation E Series Network Walkman with 4 GB storage supporting MP3, WMA, and AAC files. It uses a 30-hour lithium-ion battery with Bluetooth, speaker output, and photo playback while sharing the body shape of the contemporary S780 series.

The speaker K variant marked the final entry-level step of the E line. It takes that same very compact E083 platform and gives it a more casual-use retail framing, but the core story remains the same. This is still a compact, low-friction, very self-contained Walkman from a point where Sony had become much better at making modest players feel complete instead of compromised.
