They’re pretty good noise wise, but if you want them to be quieter you definitely need to lube the stems a bit. When you get to the tactile part of the switch they’re pretty scratchy and loud, but still quieter than the zealios.
There is a lot to like about this switch. It is very tactile but also quiet. It doesn't feel too mushy on bottoming out. It is also a good candidate for spring swaps (55-57g springs work great).
My favorite switches so far. Very satisfying tactile sensation, and very quiet bottoming out. Great if you are more about the physical sensation of a switch, and not so much about the sound.
They offered the lowest price plus shipping for these switches, and shipped and delivered quickly.
Honestly live the tactile switch while being silent. Keeps my wife happy when I lurk at night.
