Waterproof Speaker

I finally found a waterproof speaker that I actually trust to be waterproof. With summer coming up, I'll be spending a ton of time at the beach and at the pool. A waterproof speaker is pretty much a necessity at both of these locations. Plus, I can take it in the bathroom during shower time and not worry about all the condensation on it. It is super compact and black so it goes with everything. Huge bonus since I like to change the covers on my iPhone all the time. The USB charger and input jack are protected so that they don't get wet when it is around water. I also love the bonus of being able to use it for my son's homeschooling.
