Read Gregory Schmidt’s review on the brand-new sound amplification case, CandyShell Amped in his article “Cellphone Cases to Prepare You for Anything, Even a Flat Tire.”

“BIGGER SOUND Speck has been a leader at creating innovative cases. In 2012, the company was awarded a patent for the design of its CandyShell case, which fuses a hard exterior with a rubbery interior. Speck also devised a way to embed vibrant, high-resolution graphics that resist scratching.

Now, Speck has come up with a sound amplification case called CandyShell Amped, which produces louder and clearer sound without cables, external speakers or extra batteries. To achieve that, the case redirects sound from the phone’s loudspeaker through a horn-shaped cavity to an exit on the side of the case. Speck says the amplification provided by the case, which will be available on Friday for $45, can double the volume of a phone’s speakers.”
