SimplyVibe SV-S300 2.1 Channel w/ subwoofer Portable Speakers (Gloss Black) for iPad, iPod, iTouch, iPhone, MP3 Players, Laptops (Mac/ PC) - (USB Or Battery Powered)
I bought this to take my use as a travel speaker. The \\"subwoofer\\" feature just clips the highs, it will sound a tad muffled. But hey, it was cheap!. If you want top quality in a portable speaker, go to Bose. If you just want something to bring some sound, get this. It is pretty small to boot.
