I've got several brands--the most comfortable, thus the most used, are a pair of AOSafety folding ear muffs. I try to always keep a set of muffs on the jointer, planer and table saw and near the router table as well. Emphasize the tools with universal motors, which are the noisiest. Wearing hearing protection all the time any power tool is in use is probably a good idea.
I've got several types of the "in your ear" kind, and find they do generally work a little better, but are something of a nuisance to get in and sometimes to keep in. They are also sometimes harder to FIND, so for two reasons, they're less likely to be used.
Wish I'd started wearing hearing protection 40 years or so ago. Now, any of the protectors are a stopgap to try to retain what hearing is left for as long as possible.
