Even as portable wireless speakers get more and more compact, there is clear value in a product such as this mobile speaker cover. One does not always remember to bring his bluetooth sound system along where it might be needed, or perhaps he doesn't even have the space.
Developed by Yoann Lechopier and Michael Ward, the Impulse Speaker Case is compact and hard to leave behind, given that it fulfills the second function of protecting your smartphone at all times. The hi-tech handset shield is thicker than you're used to, though, because it features four built-in transducers with the space for fuller audio, as well as a rechargeable battery and a USB port. The designers of this mobile speaker cover have tapped into a gap in the market with this product.
