The rugged, portable SRS-XB13 is easy to carry around with its special strap. This small speaker has it all: with extra bass and a sound distribution processor, it produces rich sound. A passive radiator works with a full-range speaker to optimise low frequencies for richer bass. Waterproof and dustproof to IP67, the speaker sounds as good outdoors as it does indoors.

This way, you can conveniently take calls without disconnecting from the speaker. With this portable speaker, your favorite music is always wherever you are.
