Today I have received my new headset, and connect to the PC these worked without problems, for some reason decided to update the drivers and firmware for the headphones, and after doing that, now it does not work, turn on, but no sound. Any solution? There a way to return to the previous firmware? Please help me to solve this problem I try to find about this on internet but not able to find appropriate solution on this. Please share your knowledge with me thank you.
