Have you used silicone ear putty before? Was it effective at blocking out noise?

I just bought some “silicone ear putty”. They are like drops of silicone putty that you mold to the external ear to keep water out of the ear canal and block out noise. I am really looking to just block out noise. I followed the instructions the best I can and they aren’t really blocking out much. I had some foam ear plugs earlier and they were crap. I’ve had better foam ear plugs in the past… Have you tried both? Is there a way to make the ear putty work well or am I better off with good (3M) foam plugs?
