Apparently none of you have heard Style talk...He's high pitched, squeaky, and dare I say, sounds like a homosexual. His voice is farthest from masculine.
All of these factors: looks, voice, haircut, body shape etc. can be overcome by solid game. That is the point of this site, and it's been proven over and over and over again. So what if some study says that "voice" is the most important factor in attraction. Whatever...Our game should trump it. And it can trump it if it's good enough.
Now granted it helps to have all factors on your side, but sorry, it's just not true that if you don't have an attractive voice, you're screwed. You're not if you're a DJ or PUA.
