So what is the difference between razer kraken and razer kraken pro? I have limited budget and i dunno which one should i get http/www.gaminggear.bg/razer-kraken-black or https/www.ozone.bg/gaming-aksesoari/slushalki-s-mikrofon/razer-electra-black-edition or https/www.ozone.bg/product/razer-kraken-usb/? the last one looks like kraken pro so yeah. Or all of them aren't that good and i should save for kraken pro?
