Keyboards

Hello! So I've recently bought a BlackWidow Chroma V2 and I absolutely love it. But I wonder what the headphone jack is for. ~Tim

Yeah i bought this keyboard and i cant use. FN 1-2-3-4-5-6-7-8-9 for changing the light. What can i do?

Hi All, Apologies if this is the incorrect forum....... I got the keypad for xmas and want to know if there is a blank template I can put my saved profiles to or print out a blank one and manually write in my keys?? Cheers
