Meet the OMO+: a waterproof portable speaker you can use while in the pool to have more fun. It has a 11000 mAh battery which means you can use the device for over 8 hours. The OMO+ can be submerged to 1 meter for 30 meters. It features Bluetooth 4.0 technology.
OMO+ can charge both iOS & Android devices. It also lets you put on a light show at night. Yet another interesting Kickstarter project.
