Welcome to the forum! This is a topic that has been covered quite a bit in the past. I know the search function here is a little difficult to use so let me help you out a little. Howard Leight Sport are what Iuse and recommend. ESRice reviews another pair and I would trust his opinions as my own.
inexpensive - Howard Leight
medium - Peltor T7
better quality - Sordin
There are others to add to the list, but these are the ones I own and have experience with.
