Didn't work for me
If these work for you, then they're actually a pretty good value because you get 4 different types of earplugs for around $11. You get 3 pairs of moldable silicone earplugs that you can squish into a shape that will fit into your ear, and then 3 other pairs of earplugs - blue ones that are supposed to be for sleeping, gray ones for work, and then the red ones that are shown on the ad, which I guess are all-purpose ones. Unfortunately, none of the 4 types of earplugs worked for me. Sound level was basically the same with them in my ear. The moldable silicone ones worked the best, but if I'm going to use those, I might as well just use the soft foam earplugs that I get free from the airlines when I travel. The other earplugs would only reduce the noise level if I really jammed it into my ear so deep that I had trouble getting them back out.  It would be better if there was a chain or string attached to the ends of the earplugs so that you can easily pull them out.
