This little gadget, called the Lil' Wiz lets you bring along big sound - turning almost any solid surface into an amazing sound system. You connect it to your sound source (computer, smartphone, music player, or tablet), and then attach it with the built-in suction cup. Some of the models connect to your device via BlueTooth, and there are also options that include a reader of a micro-SD card- where you can put your playlist on the card and have no connection required.
