I got this for work, so I can listen to music properly. I basically use it for headphones only.
The sound isn't bad (though my Cowon D2 has better sound), but it's way better than the onboard crap my computer here has, plus it's nice to be able to reach high volumes without losing quality.
In short, I'd say it's an OK device with mediocre sound quality, but for the price I don't think one could/should expect much more.
I'd buy it again.
