The Blue Bluetooth Shower Speaker has been a very popular deal with our readers, but there's just four days left. For $39, you can get a water-resistant speaker built for your shower. That means music or podcasts or whatever sound floats your boat while you bathe, without worrying about wrecking your iPhone. Huzzah! It has a rechargable battery, works up to ten meters from the source, and connects to your iPhone, iPad, iPod, Mac, PC, or Android device via Bluetooth.
