Sony Ericsson’s new MS500 portable speaker connects to your devices via Bluetooth A2DP, and has a range of about 32 feet. It comes attached to a lanyard and has its own set of play and volume controls so you don't have to have access to the device its connected to.

Two AA batteries provides up to 5 hours of music, and the splashproof shell means you can take it to the beach or pool. No pricing info or release date is available at this time.
