(My wife has a Steelcase Leap, which I can say similar things about.)
The real problem is cheap headsets with poor mics and people not knowing how to turn the fracking gain down.
Though at home id just swap out my laptop and stick my works one in and plugin my Claret Pre 2 for the mic and the Shitt Audio stack I use for heaphones.
Also higher quality boards with nice heavy plates lower the pitch of the sound so it's less intrusive (in my experience).
I have neighbors with mechanicals that bother me so bad I’ve had to pack up and go home for the day. This is over music on noise canceling headphones.
Different people actually have different amounts of trouble with this, with some having lots of problems. Just lucky I guess?
To install them, find the cheapest kind of ballpoint and pull out the tip and ink tube. The body tube is just the right size to press the spacers onto the key stems. It's miles easier than anything else I've ever tried.
Before spacers, the helpdesk complained about my keyboard noise. The helpdesk! After, no one did.
But hey, I see 80 col Vim developers, too, so everyone’s needs are different.
