CORSAIR HS70 wireless (With USB dongle / Wireless USB transmitter) mic suddenly stopped working

[tenz]

I was using my device as usual, mic was working just fine. It was working the previous day. But One day I plugged in the Detachable microphone boom and the mic just stopped working.

Things I tried.

• I tried it on windows
• i tried uninstall and reinstall the iCue with removing this device from device manager
• allowing mic in privary
• input audio to 100%
• reset the headphone

Nothing seems to be working. I have seen others are facing similar problem. The mic is fine. I tried it on my HS50 wired. it works fine. I tried to reset.  (while power ON , hold the mic button for 15+ sec. The headphone turns off, but does not cycle power. How to reset HS70 wireless ( not HS70 pro ) proper way?  )

 

On iCue software, I can head Mic on / off audio prompt.
