My Razer kraken ultimate headphones don't work

First of all, I don't speak English, I'm using the google translator, but, following the topic, 8 months ago I bought the razer kraken headphones on the recommendation of a friend, and within those 8 months in which I have used them, it has not happened nothing, but lately, suddenly only the audio from the headphones and not the microphone is disconnected, I tried to see posts on the razer forum but everyone tells me to reinstall synapse 3, which I already did several times and that just didn't work for me, ¿ what should i do now?
