Earplugs are fussy things. But usually as long as they're not 'corks'(the old yellow foam cylinders)you should be fine.
Least with Howard Light it's Greens<Pinks<Oranges. Greens should be more than enough and are 'softer' if you've got a smaller ear canal. All of them work well.
You have to ensure you're putting them in correctly. Read the box. Roll the plug in your fingers, reach your other arm over you head to grab the top of the opposite ear, gently pull on the top of your ear, and insert the plug. You should feel & hear it expand forming a seal.
You can reuse foam ones a couple of times(can even get them corded), but be very, very wary of infections. And always put the same earplug back in the same ear(thus you don't spread anything).
