I suggest trying a cheaper pair to begin with, then step up once you know how you'll like them. The cheaper set can always be held on to as a spare or loaner pair.
Howard Leight Impact Sport is my go to (~$50). They are fine for outdoor use behind the gun, but in an enclosed or covered space, or as a spotter off to the side of a braked or otherwise loud gun, they should be used along with some plugs. Sound is decent, with good stereo perception, wind noise is minimal, and they are plenty comfortable to wear for extended periods. I wear them even when hunting.
I've also used the Walker Razors, and though they are more comfortable and have better sound quality than the Howard Leights, the mics are omni-directional, so you can't tell the direction the sound comes from very well. They also have horrendous wind noise. Still great for the bench, but I can't stand them out in the fields.
There are better noise reducing muffs, but most are too bulky for a proper cheek weld, so I prefer adding ear plugs underneath the slimmer designs instead. As mentioned, all you need is a few more DBs of reduction, so you can put in a cheap and comfortable foam plug, then just turn up the volume on the muffs to still hear conversation and environmental noise better.
