Meet the BRO Ball: a Bluetooth speaker and football that plays your music and keeps you entertained. It is waterproof and rugged. It has a built-in battery to charge your smartphone. It is not only waterproof but is designed to float. It is also resistant to dirt and sand.
BRO Ball has a range of up to 50 yards. It glows in the dark, so you can use it day and night. More information is available on Kickstarter.
