The click remains the same, only the noise when it hits the bottom is dampened. So with the brown ones, the O-rings probably have a clearer influence. I have the brown ones in the office and the blue ones in the home office, where I don't annoy anyone, and after a short experiment I decided not to use damping because otherwise I would miss something in terms of feel. However, I have never tested two whole keyboards with and without damping directly next to each other, but only on individual keys with O-rings from the diving equipment ;-)
