The Sony SRS-XB100/L delivers powerful, clear sound from a super-compact and portable body. Engineered for life on the go, it features an IP67 waterproof and dustproof rating, a durable exterior with UV coating, and a battery life of up to 16 hours. A Sound Diffusion Processor expands the sound for a more immersive experience, while the versatile multi-way strap makes it easy to carry or hang anywhere. This speaker also includes a built-in microphone for hands-free calling and can be paired with a second unit for rich stereo sound.
