I tried the product reset (30s off, 5s plugged in, 60s off). This occurs in either the left ear or right ear reproducible. When it connects to the computer youtube plays fine. I have minecraft loaded and it also works fine until I do something specific in game. As soon as that happens one of the ears pops and the high frequency screech starts until I turn off the headphones. This has occurred before, but never in such a controlled/reproducible way.
Sorry to hear this @whitney, can I please ask if you have tried updating the headphones at all? Also, just to confirm, this only happens when you are gaming?

TL;DR; Disable microphone
I could hear the faint sound of my keyboard with the beep and screech, then I noticed the microphone icon was on at the bottom-right corner of the windows. Hovering over the icon I found out my game (Starcraft 2) was using the microphone by default even when I don't use the voice chat. (For this particular game though, "Disabling the Voice chat" isn't enough to fix. Refer to this video https://www.youtube.com/watch?v=SKlqMJyA4z0 for fix.) I hope other folks can find a similar solution to their problems.
By the way, the video above briefly mentions one solution that could work for other applications, which interestingly doesn't work for Starcraft 2.
If this helped you in any way, please 'Like' to help others find this solution!
