Acoustic amplification from a case for your phone! This case for the iPhone 5 boosts audio volume while simultaneously directing it toward you. No need for batteries! It's all done by channeling the sound from the speaker into a chamber behind the phone where the air can really get moving! It's then redirected out the top of the phone straight at you!
Great for having speakerphone conversations in noisy places, or cranking up the tunes at home.
Tapered design feels very comfortable in the hand despite some added thickness. Curved shape gives your phone a cool, unique profile!
