Crackling and static noise of Wireless Headphone
 

I have a SteelSeries arctis 7 and I'm fed up with it due to its Crackling and static noise. I'm also using also wireless keyboard and mouse.But no issue. Does any body know what's the cause for this issue? The headphone isn't too old be troublesome

It sounds like the transmitted signals from wireless keyboard and mouse might be interfering with the headphones. I've had also similar problem lately, with trying out quite old wireless headphones I've bought years ago. The connection between the headphones themselves, and the receiving / transmitting station, simply terminated and resulted in constant static, nothing helped despite fully charged batteries, and switching between three available channels.
I'm also using a wireless mouse so not knowing any better I'm guessing that might be the culprit. Connecting wired headphones there is no problem at all however, so it's certainly not the headphone jack on the computer.

According to versus comparison, If you're using wireless headphones and experiencing a crackling sound, the issue may very well be because of some connection problems. The most common problem is something called Bluetooth interference. This happens when something gets in the way of the wireless signal from the audio source to your headphones.
