I’ve found this rather cool cassette ipod speaker which is a bit retro if you want something different for your ipod.
The Retro Cassette iPod Speaker plugs into any 3.5mm audio jack and is perfect for all your tunes. I quite like the retro feel about it as well. It looks cool too.It’s lightweight and compact.
If you want one, the Retro Cassette iPod Speaker is available for $19.99 from Only Hot Trends.
