I need your suggestions. I'm interested in buying an MP3 player (NW-E405, NW-E407, NW-E507, etc.). However, I've been hesitant because they're either very expensive, in poor condition, or both. I found a seller with one for sale, but the NW-E407 doesn't operate. It does have a working battery and turns on. I've read that some of the NW-E400 series require specific software to function.

Since I'm young and don't have much money, I'm asking if I should buy this device and hope to find a solution. If I get enough viable solutions to make the device work, I'll buy it. Please share any knowledge you have about this series of MP3 players.

Thank you!

as the title suggests, i wanted to post a tutorial to how i downloaded music to my nw-e405 because i had to scour all parts of the internet to figure it out. this works with windows 11!

first thing you want to download is jsymphonic. i downloaded the latest version, which is ode to freedom. it should come with a readme, which has step-by-step instructions that are super easy to follow. the issue comes with step 5, which is generating a key file, or a DvID.DAT. the nw-e405 is a third generation player, which means it needs a unique encryption key in order to play music. using this blog post, i was able to deduce you need to download the original sony software for the walkman, which miraculously is still compatible with today's tech. link is here: https://www.sony.com/electronics/support/digital-music-players-nw-nwz-e-series/nw-e405/downloads/W0001936?model=NW-E405

once you download the file, and follow the installation instructions, you want to add the downloads to the walkman. inside the folder should be an application called "CopyTool"

run the item as an administrator, and it will add the DVlD.DAT files exactly as you need onto your walkman, under the folder name "MP3FM".

once you launch jsymphonic, select the third generation and you should be able to transfer music! happy listening!
