Assuming these are the white-stemmed versions in the render and not the clear-stemmed ones that usually have the name "Hush" instead of "Deep Sea", these might be the best silent switches Kailh have made to date. The clear-stemmed ones are also great, but slightly less smooth.

Not the most quiet silent linear out there, but easily has one of the most pleasant sounds. I'd say the same about how the dampeners feel, too - these are very satisfying to use, if maybe a little light for me.
