We’ve covered no shortage of smartphone and computer speakers, but the Spherical Ballo Smartphone Speaker really jumps out at me.

Designed by Swiss designer Bernard Burkhard, this speaker is mono, but promises 360-degree sound. If attached with a stereo splitter, however, you’ll be rocking both left and right. Designed to be used on a hard surface, the Ballo is small and portable. The best part? It’s just $30.
