The listing, Sunstech MP3 player 512 MB has ended.
This is a little AAA powered MP3 player. It has the USB built right in, so you don't need any cables to put it onto your computer. It also has the capability to record audio and play it back in a WAV format. It pretty much operates like a flash drive- plug it in, add the music, and go. It's all pretty self explanatory.
I believe it only supports WMA and MP3 files.
3 1/4" long, 1" wide.
On the front it says: MP3/WMA Digital audio player DP-F165, and has a play/pause and record button. On one side it has a hold switch and a menu wheel, the other side holds the volume controls and the headphone jack. on the top is a little loop that seems like it could be used for a lanyard, and an opening where the microphone (for recording) is located.
The top part comes off, which is where you can see the USB connection is located. The battery goes in the back.
Any questions, feel free to ask, and I'll answer them the best I can!
