Meet the BRO Ball: a Bluetooth speaker in a football that plays your music and lets you play catch. It is waterproof and floats, so you can use it at the beach easily. It is tough enough to survive high velocity impacts. It has a built-in battery that charges your smartphone. The device has a range of 50 yards.
The BRO Ball plays your music, charges your phone, and lets you play games with friends. This project is already on Kickstarter.
