With one tap, BumpOut's game-changing Expansion Mode™ expands to create an internal acoustic chamber that lets you fill the room with rich bass and powerful, high-quality sound you would never expect from a speaker the size of your smartphone. You can even pair two together to create an immersive stereo sound. BumpOut is dust and water resistant, so you can take everywhere with confidence, and features an easily rechargeable battery that provides up to 10 hours of continuous listening.
BumpOut can easily attach to any smartphone and mount onto any flat surface thanks to its patented Coin Technology™. These reusable adhesive "coins" create a strong and secure hold, but can also be moved and repositioned as needed.
