Wherever you go, there's music in the air. The speaker pairs with iPad (or iPhone or iPod touch ) over Bluetooth wireless. Place it wherever you want within 50 feet (15 meters) of your iOS device. Dual two-inch drivers deliver rich, stereo sound and plenty of bass. You'll hear it all loudly and clearly-even from across the room. Listen for up to ten hours straight on the rechargeable, internal battery. No need for costly and wasteful disposable batteries. This compact speaker fits easily into the included travel case or your laptop bag. Great sound can go with you-around the house, over to a friend's or when you travel.
