Mpow AquaPro Bluetooth Wireless Speaker! Our good friends at Mpow have provided me with one of these bad boys to try out and review and I'm sure glad that they did. This small speaker is shock proof. dirt proof, and water proof so it's perfect for the outdoors or for the shower. Let's be honest here, friends. We all do our best singing in the shower and with this Mpow water proof speaker, we can have the music to back us up! But before I get into my experience with this bluetooth speaker, let's talk specs!
