I own a NW-E005 Walkman and am quite happy with it but listening to the same track using the same headphones on my Sonyericsson K800i.The K800i sounded better in the sense that it had better stereo and could hear some quieter sounds I could not hear on the NW-E005. I was quite diappointed that the phone sounded better than the dedicated player which is why I am interested if this one is any better.
