The MS500 speaker is the ultimate accessory for any dedicated pop rocker or dancing queen - small enough to fit into the palm of a hand and so light it can be taken anywhere and everywhere. The MS500 speaker is designed for the outdoor environment with a durable splash proof shell and a handy strap which makes it perfect for attaching to a bag, or hanging from the wrist. The Outdoor Wireless Speaker MS500 is compatible with most Bluetooth phones from Sony Ericsson and other brands.
