Audio Quality
How does the audio sound? I would say it sounds fine to me. For me and my purposes, at regular volumes, I am pleased with the audio quality. Cranked all the way with a driving tune and it does get muddy. I would, however, like to attach some higher quality earbuds and see how it sounds. From what I've read in various forums, etc, it seems to me that the earbuds are the limiting factor with most mp3 players; probably true in this case also.

The vp8350 recognizes m3u playlists from Winamp. Just upload your playlist and songs and you're good to go. Once uploaded, you can add other songs on your unit to the playlist.

According to the manual you can also create a playlist using the unit by somehow "copy, delete, then pasting" into another folder. Haven't tried that one yet.

Audio Sweetening
It's got an equalizer with 7 presets built in and one user configurable preset (you have 3 settings you can play with: bass, treble, 3d)

Slideshow with Music
Yes, it is possible with the vp8350


It uses your headphones as the antenna so if you try playing it without the earphones it doesn't pull in the stations too well.
