Review Snipit: Today Ive got a unique little product for review called the XMI X-Mini II Mini Speaker, and its exactly what it sounds like, a mini speaker. Sure there are many of these types of products out there and Ive tried a few of them myself, but this one is the best of the bunch really. Its small, portable and has excellent sound. One of the best features I think is that it uses a built-in rechargeable high capacity battery that gives you about 11 hours play time and charges from any USB port.
