I bought this guy a few days ago on Ebay...10 bucks shipped. I haven't gotten it yet, but I don't expect too much for 10 bucks, just to be able to listen to music clearly (and still hear the world around me) when I'm paddling long distances. It's "splashproof" whatever that means, I'm going to test it empty with a hose before I put my phone in it!
