Just to inform you and your viewers that the seal that contains the charging mini usb and the port for your phone can be lost open as it's completely water proof!
there needs to be like a strap for the float because it will most likely fall of with all the splashing around and then you wouldn't be able to find it at the bottom of the lake
Want a small waterproof speaker with good sound? Spend a bit more and buy a Bose micro. I just did a sound comparison; here at home between my Bose and one of these UE Roll's someone's left at my house (and don't want back),. Bose sounds huge. UE sounds lame. Something you wouldn't care if you left it behind somewhere...
