Sony SRS-XB13 Portable Bluetooth Speaker-Black

The SRS-XB13 is durable and portable. It comes with a specially engineered strap to make travelling with it easier.
A passive radiator works together with a full-range speaker to enhance low-end tones, giving bass a boost.
The durable exterior and multi-way strap makes this speaker ready for just about anything. Hang it from your backpack or on your wrist or even from a parasol when you’re out in the sun. The downwards-facing speaker will create a waterfall of music that engulfs you in the rhythm.
Don't be fooled by its compact shape, this little speaker packs major surround sound. The Sound Diffusion Processor expands sound in any space, with its DSP technology.
Waterproof and dustproof with an IP67 rating, this speaker is just as good outside as it is inside. Take it to the pool, river or park, and you can listen to your music while you and your friends enjoy the sun.
