When I worked hospitality, a Karen was someone who automatically assumed that anything not exactly how they wanted it was a personal slight, that you as an employee are not important enough to fix it for them, and that anything short of grovelling is grounds for being fired.
If they listened to you explain why something occurred or why it was the way it was, not a Karen. If they didn’t threaten to escalate because you weren’t offering enough compensation, not a Karen. If they didn’t blame you personally, not a Karen.
And, funny enough, most Karen’s I’ve encountered were men in their mid 40s
I literally got the Acrtic Nova 7 a month ago, and I daily drive OpenSUSE. There were no issues getting it set up for normal use, but Sonar doesn’t have a Linux version and as far as I could find there are no instructions to get it working so all of those creature comforts will not work.
One thing to note is that if you connect to Windows via Bluetooth and not the dongle, make sure to unpair the headset before wiping Windows. I ran into this because I had it connected to my old phone and had to unpair it to connect it to my new one (the headset will not pair to a new device unless intentionally unpaired from the old one)
