Sony SRS-XB13

A passive radiator works with a full-range speaker to optimise low frequencies for richer bass. The rugged housing and carrying strap make this speaker the ideal companion for any situation. The speaker can be hung from a backpack, wrist, or even a parasol on hot days, and when pointed downward, it brings the sound to where you are. This compact speaker surprises with fantastic surround sound. The sound distribution processor uses DSP technology to fill any room with sound. Waterproof and dustproof to IP672, the speaker sounds as good outdoors as it does indoors. You won't have to miss out on your music while sunbathing in the pool, by the river or in the park. The battery lasts up to 16 hours - for long party fun. A new battery indicator shows you when you need to charge your speaker right on your smartphone. Need to make a call? No problem. The speaker's built-in microphone lets you make hands-free calls whether you're at home or on the go, thanks to the speakerphone feature.
