My husband doesn't find them loud. Especially since he plays with a headset. It depends on what you perceive as loud. I, for example, can hear them very clearly (wife) unfortunately he had the razor before ... ??? I can't tell you anything more specific. However, he really likes it and says it's like the old Logitech mouse from the old days, only better. He is grateful that I got it for him. The only thing is the price. The mouse has a lot of good features, but if you have very large hands I would honestly advise you not to use it as it is really a delicate model.
