I want to replay some lectures from CD. I want to just hear the presenter and, if possible, jump to different points in the lecture. It would need to run from batteries.
So I'm looking for something like a CD Walkman with its own little speaker.
I definitely don't mean the large all-in-one "beat box" players with CD, radio, and cassette player with loud stereo speakers and which drink batteries.
How well represented amongst the many different types of portable music players currently thronging the shops is such a thing?
