Boom boxes are probably best left in the past, but if you want to relive the old days, then check out this Innovative Technology Boom Box. It supports both your iPhone, iPod, or any MP3 player via an auxiliary audio input.

You can dock your iPhone into the cassette deck, and turn it into an expensive cassette tape. It also sports an SD card slot and a USB port so you can record live music from the built-in FM radio as MP3 files.

These speakers may be small enough to fit on a keychain, but they pack some power. These little speakers are more than powerful enough to use when listening to your MP3s on the go. Just plug your iPod or MP3 player into the 3.5-mm audio jack.

Each version has a built in USB-rechargeable battery pack that will give you enough juice for about 2.5 hours of playback time. That’s pretty impressive for the size. They’ll cost you $25. Small speakers, big sound. What more do you want?

If you lack a pet that you can walk and find yourself feeling somehow left out, fear not. If designer Inbal Tyagi has her way, you’ll be taking your music for nice romantic walks in the near future. Inbal Tyagi likes to design clean, smart and simple things. So naturally she gave the boom box some wheels.

And what we have is a large vacuum cleaner sized boom-box that is a rechargeable MP3 player powered by energy-batteries and a dynamo. Great in concept, but I have better things to do then push a wheel around and avoid awkward stares all day.
