Handgun safety question

Did not know where to post this and since I’ll be shooting handguns thought I would ask here. If there is a better place please let me know.

Planning to buy reusable in ear protection to wear under my over ear protection but don’t know what to get. Thinking I want something that will protect my hearing from 9mm but when over ear protection is off I can hear someone talking (even if they are somewhat muffled).

I want it that the in ear will stay on at all time. Any suggestions on what I should consider? Wanted reusable ones instead of foam.
