Query: Blocks out most sounds

I got this September because I had just moved into my dorm and suite mates, fridge and ac were really loud and annoying. (paper thin walls) I've gotten more used to such sounds but these ear plugs block out most sounds such as keyboard / mouse clicking and fridge humming. You can still hear people talking if you occasionally, ac blowing and constant white noise similar to a sea shell because of the way it fits in the ear. I also got used to the white noise but still these are pretty good.
