Type of ear plug doesn't work at all for me

I don't notice any difference with these in. But others that are similar with the 3 rings don't seem to do anything either. And problem with this type of plug is you have to insert it entirely in your ear, which is too far to put something in your ear. With the foam plugs I can put them in as far I need to for the situation and they are effective even halfway in. These are not and they just fall out a lot. But it's not anything wrong with this brand, juts the type of ear plug.
