HTC has released not one, but three ads titled "Battle of the smartphones", showing off some of the One M9 superior capabilities and features, including the flagship's front-facing UltraPixel camera, BoomSound with Dolby Audio front-facing speakers, and the Snapdragon 810 64-bit Octa core processor (4 x 2.0GHz + 4 x 1.5GHz), all while making fun of the iPhone 6 as well as the Galaxy S6 for the lack of those features.
According to HTC "In a blind test that pits smartphone against smartphone to see which is better when it comes to CPU speed, Sound, Selfies, without the logos getting in the way. The jury is composed of everyday passersby. The results are surprising".
