I bought this mainly to listen to music while at work. I was going to get another creative mp3 player but wanted something that could do more. Listening to this through my akg headphones and my car stereo for a couple of days, then going back to my zen vision M I noticed how terrible the sound is with this thing. Are there any add-ons or audio card type devices that can make it better? I've been playing music with PowerAmp by the way and have adjusted the equalizer. I was going to get the Ziio but liked the idea of the 250gb hd which is very nice. But if this is the best the sound is going to get I might have to look elsewhere. Thanks, any help is appreciated.
