Presumably you mean amplified speakers -- tho a traditional 1980's boombox (really tasteless big portable radio with cassette player) with a line input would do.
Frankly anything with the standard headphone lead as an input would do -- including some of the speakers sold as iPod accessories.
Trying to research a good boombox for my Sony mp3 player (S738F) is like trying to find a unicorn. Every mp3 boombox review is centered around iPods--even here on cNet. And I know that there must be some great non-iPod ones out there. Can someone please clue me in on a couple things:
1. Are there any decent sounding boomboxes out there that are compatible with my Sony S738F mp3 player?
2. If not, what's a good mp3 boombox I can rig my player up to? How do I do it?
Thanks for reading my post.
