There are no limits to where or when you can enjoy your favourite music with this black portable wireless speaker from Sony. As it's portable, you can take the party wherever you choose - whether that's outside, poolside, or just in your front room. The design is dustproof and shockproof, so it's ideal for an outdoor camping trip. It's waterproof to IP67 standard too, so you don't need to worry about taking it to the beach or pool. Carry your music further with the Sound Diffusion processor. This clever technology distributes sound much more evenly, spreading sound far and wide around your venue, without losing quality. And, the SRSXB100B has up to 16 hours of battery life, so you can keep the party going all night.
