Corsair 2100 Wireless Headset crackling sound when multi tasking

Hello for couple of months I am having issues with quality of sound on my Corsair 2100 headset. When I am opening new tabs in the browser (Google Chrome) or opening new programs like Thunderbird I hear crackling sound in the headset for a second or two then it is back to normal. It happens especially when I open browser or new tabs while gaming (I use two monitors but I am gameing on only one).

I tried using different USB port, and uninstalling drivers but the problem persists. I tried to ignore it but I can't, it is very annoying, especially since I have been using this headset for over a year now and never had any problems before (except the quiet microphone but I fixed that by installing EqualiserAPO software).
