Recently got my F805. Before I had doubts that the blue might look a bit feminine, but once I got it in my hands, I really do think its a beauty.
Sound quality wise I wouldn't say its much better than X1060, but rather different approach.
X1060 is more organic and lush, great for long listening sessions, but at the cost of more confined soundstage.
F805 is more neutral, greater soundstage, but sometimes i miss the dynamics of X1060.
I insisted on buying the Japanese version is because of the noise cancelling and of course the color choices. Noise cancelling works quite well for school environment as it effectively drowns out most of the humming and buzzing from computers yet I can still hear people when they talk to me.
To my surprise, the noise cancelling headphones that comes with F805 also works on the X1060 (which isn't listed on the Sony jp website). And to be honest, I don't think the stock headphones are half bad, it sounds fine for on the go, maybe just a little crowded soundstage thats all.
