I've tried the product both in water and out of water and have to say what an amazing piece of technology!!! The 4gb of onboard storage is great, although a little tough to navigate when its in your ear. I found when wearing them whilst walking I hear every step I take as a 'thud' in my ear - I'm assuming it's the vibration from my feet up, or maybe the earbud against my ear? Either way, it can be quite distracting. Ambient mode works okay. The touch controls are a little temperamental too, finding the spot can be a little difficult - maybe just need to practice more. And the 3 hour bluetooth run time is a little limiting. The case is cool, and locks shut into place with a satisfying click! If it were water and dust proof that would bring a lot more peace of mind.
