call problem

I have a razzer barracuda headset, a few hours ago I am trying to make a call from my mobile device with the headphones connected by Bluetooth and as soon as I start the call the headphones turn off, like this all the time and from several mobile phones, I need help It can't be a problem with my mobile because it happens in several, and for spotify, games, YouTube etc. if it works... they only turn off on calls
