Working alone in peoples' houses all day, (I don't do that any more), I always brought CD's and a boombox. They are hard to find. Sony still makes one (with "X Bass!")
Lots of passing-though other trades guys would ask about it, since it sounded pretty good and played rather loudly. It's about $120.00 American.
Edit: I forgot to include, that, in order to sound that decent, it is rather ghetto-dimensioned. Remember breadboxes? It's about that size.
