The Eco Terra houses and protects any cell phone or MP3 player from the 4 Extremes: Water, Dirt, Snow and Shock. The Eco Terra is IPX7 waterproof tested and approved. What does that mean? It means the Eco Terra is not just water resistant but actually waterproof! So don" t worry if it gets knocked in the pool, falls off the boat, drops into the river, lake or ocean - your device is 100% safe from the harsh elements. It even floats! Uniquely designed air pressure release valves ensures your case is closed water tight yet easily opened at low and high altitudes. Even the external headset jack is waterproof. The Internal waterproof cavity houses your music layer/Smartphone as well as extras such as cash, credit cards, or extra car key. When using an iPhone or iPod Touch you can utilize the Eco Terra" s external buttons to play, pause, skip forward or back between songs in a play list or even change the volume of your music without opening up the Eco Terra" s waterproof compartment. For other audio devices with the flip of a switch, the Eco Terra will change the volume up/down (skip and pause not supported via the external buttons). Play the Eco Terra for up to 25 hours on 4 C batteries (not included) or plug into the wall outlet for unlimited play. The Eco Terra does not charge rechargeable batteries but works perfectly with them. For convenient transportation use the built in moveable handle, included adjustable carrying strap, or batten down the Eco terra via the 4 tie down points for active adventures.
