SONY NW-S784 WALKMAN - Brand: SONY - Model: NW-S784 - Color: Black Initialized. As a functionality check, I have confirmed that the power turns on and all buttons respond. I was able to import and play music from a computer. Please understand that this is a used item stored by myself, and I ask for your purchase if you are okay with this. Instant purchase is welcome. The reason for being junk is because the Bluetooth connection is poor and the screen condition is not good. You can listen without problems with a wired connection.
