Soundsoul(TM) Magic Cube Rechargeable Portable Bluetooth Wireless Speaker with 3.5mm Audio Port for Iphones, Ipads, Android Cell Phones, Touch Screen Tablets, Macbooks, Laptop Computers, Mp3 Players & Portable Cd/dvd Players, Black
Great value.  The connection quality isn't always the greatest but for $20 its just what I needed for my office.  Easy to pair too.
