Flip it, wet it or bump it, nothing will stop the rugged Splash proof SB2000 DOT portable speaker from kicking out big sound from its big 3” driver. Built-in Bluetooth music streaming connects wirelessly to devices, making it even easier to burst out your tunes anywhere. Its convenient, splash proof ability (IPX 4) is achieved using a patterned, silicon rubber skin, which also enables “grip and go”. The built-in rechargeable battery allows loud and clear music playback (up to 5 W output) anywhere, and auto sensor allows for easy on / off. As well as music streaming, a built-in microphone enables hands-free phone calls wherever you go.
