Rad said: It’s extremely portable, and its build quality is solid. At moderate volume levels, it offers clean and appealing midrange sound, and bright yet unbrittle highs. If you’re looking to bypass and replace the anemic sound you get from an iPod or iPhone, or perhaps a laptop, you’ll get much better sound with a Cube.

Read the SoundStage! Xperience review.

The gist: Decent sound from a tiny cube.
