Boomboxes are heavy radios with a very loud audio system, which is great for partying but even worse for the neighbors. You may switch to AM or FM with these boomboxes, and years before these have cassette holders which you can play or perhaps to record your own voice. But new-technology developments raised these old gadgets to the new level. The latest boomboxes became lighter and lightweight and has CD players or iPod holders which are just the thing for playing music without converting these. Or if you want these in a silent mode, plug the headsets and hear music on your own. If you want a more advanced boombox; then you'll want one with Bluetooth that will automatically get mp3 files from your cell phone.
