Volume control module

i was looking to the razer kraken pro, and i really love them, but there isn't any volume rocker on the cable, so i'm trying to find something like the external controller of the creative sound blaster zx. are there any solutions, or i must buy the whole card ?

you can make one or buy something like this if you dont want to spend much money 

Headphone VC

it doesn't resolve the problem :/

 

not sure i understand what you trying to do then

i want an external control module like the one with the creative soud blaster zx and the asus xonar phoebus, but without buying the whole video card

Its a glorified volume control with some hotkey sound preference settings so theoretically you could  program the same features on your keyboard I dont think there is going to be something thats cost effective for you If you have a gaming keyboard you could set up the custom keys to do the same thing and technically you would have less signal loss since there would be no hardware in between your cans and sound card. If I find something ill post it but try out what I mentioned first it may do what you need and be a pretty cool macro programming experience you could post a instructional article for us :)
