I have a Creative Zen which does not have speakers. I can hear this very well while in the kitchen drying dishes with the Zen speaker setting on 18 out of 24. Sometimes we get an audible book and it is nice that we can both listen to the book at the same time with the speakers instead of taking turns with the Zen MP3 player and the earpieces. Don't know about music, but this is just what we needed for books and podcasts.
