Ready to deliver your favorite music at the beach or by the pool, the black XB100 Portable Bluetooth Speaker from Sony features a protective UV coating and IP67-rated resistance against both water and dust. Even with its ultra-compact size and only a 1.8" full-range driver and passive radiator, the XB100 can create a large soundstage thanks to Sony's Sound Diffusion Processor. Stream music to the XB100 from any Bluetooth-compatible device, and when using a smartphone, you can also take advantage of the built-in, echo-cancelling mic for clear, hands-free calls. There's even a color-matching buckle strap for conveniently securing it to a backpack or deck chair. SRS-XB100/B
