Brando’s new waterproof Wavetooth headphone system does the underwater audio thing a little differently. Other waterproof cases bring the iPod/iPhone with you, but this one might be a little safer since it stays outside the water. The Wavetooth operates via bluetooth, streaming your music wirelessly, and is waterproof to 3 meters. They boast of 13 hours of “talk and music time”, but if you’re making business calls underwater they’re might be something wrong with you. Just make sure you’re not in a public place when you leave your iPhone unattended. The Wavetooth available now for $57.
