Sharp isnt exactly a household name for smartphones in the US, but the company has been pumping out interesting high-end handsets in Japan for years. Today the company just announced two new phones under the Aquos Crystal brand for Japan, and it says that at least one of them is coming to the US at some point. Both phones have sound processing technology by Harmon Kardon, which was also featured in an exclusive HTC One M8 for Sprint earlier this year. Oddly enough, neither model is waterproof, which is a break from tradition for Japanese smartphones.
