Yesterday my headset working fine,
Cannot pair it today, so i unpair it. Cannot find the device using bluetooth after i turn it on now.

Download the App, and it can connect.

The gaming mode and ANC mode voice still activated when i press the button or from the App.

After i connect the device and the app, it will show 

Can’t Communicate with Razer Opus X

Here is the screenshot of the error: Error in app
What can i do to fix this?
