Here is another cool Bluetooth speaker for the fans of the Marvel Universe. The Iron Man Bluetooth Speaker (BSP100) has a 600mA battery that lasts up to 5 hours, depending on how you use the speaker. When you turn on the speaker, the base lights up. The status light lets you know when a Bluetooth connection has been made.
You can get this particular Iron Man speaker for under $90 at this time.[where to find it]
