Are my Beats by Dre real..?

okay so i recently bought Beats by Dre Tours. they look legit, well, at least the back of the box does, the back of the box were Dr. Dre's face is, has a little bit of his neck showing, its not that darkish, and such. but in the front,the image of the tours, you know the white circle where the red B is? yea, it is VERY white, i opened the box, everything was in there, the beats look legit, but again, the circles where the B is on the headphones, are like silver-ish, and has very very very faded streaks running through it, but its barely noticeable, they sound amazing, and i noticed on the serial number, it says this exactly: "A..F10A" i noticed on a youtube video, he had the same serial number as me, so are my beats seriously fake? and another question, is it like REALLY easy to tell fake beats apart from legit beats? like just by the headphones. (mostly referring to the Tours) thank you.
