This outdoor wireless speaker is from Brookstone and is a weather resistant speaker that connects to your mp3 player, smartphone, tablet or laptop through the wireless dock. The speaker outputs rich omnidirectional audio from up to 150 feet away from the dock and uses 8 D batteries or the included AC power cord. Finally prove to your neighbors that you do have friends by blasting music in all directions as if you did have people over, and you're not inside, by yourself, crying into a bowl of chocolate pudding.
