Britain’s Daily Mail took a look at one of your smartphone’s favorite new accessories, and showed off what over 2x louder means:

“No matter how hard the likes of Apple, HTC and Samsung try to boost the quality of their handsets’ sound, they are still lacking. The CandyShell Amped case offers a solution by promising to double the volume on the iPhone 5 and 5S without the use of cables, batteries or speakers.”
