Sony SRS-XB13 Portable Bluetooth Speaker

The SRS-XB13 is durable and portable and includes a specially engineered strap to make it easier to travel with. But don’t be fooled by its small size, with Extra Bass™, Sound Diffusion Processor, this little speaker packs plenty of punch.
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.
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.
Get up to 16 hours of battery life to keep the party going. A new battery indicator, right on your smartphone, lets you know when it’s time for a recharge.
