Looks like from very high quality but after normal walk to my girl first party I noticed most diamonds foll off, when she come back from party it was nearly nothing. Like most headphones they are adjustable for size. I would say since he is a 10. Fits my power beat pro perfectly. Im looking out for you. You can strengthen your grip with as much weight as you like. THE WOOD SHELVES NOT INCLUDED! Dont be a pansy, if you would rather have cheap flimsy plastic struggling to hold itsef together go get something else. I am using this mouse in a 32" 1440p 240hz screen at 400 dpi, yes 400 only. Im going to mail it back to you regardless, you can just keep it.
