As speakers get smaller and smaller we never stop being impressed by how much sound can come from such a tiny place. The downside to tiny portable speakers everywhere you go? Usually there’s pretty much no bass. But luckily even subwoofers are shrinking. The DigiZoid ZO Personal Subwoofer fits in your pocket with your MP3 player and provides booming audio with 32 bass intensity settings. Unlike anything you’ve heard before, Zo uses SmartVector sound contouring tech which adjusts equalization to provide a sound that outdoes any expensive set of headphones.
