I have used different Peltors models in the past.
When using at a range, you can put your soft ear plugs in to double protect your ears.
This is especially true if people are shooting around you with muzzle brakes.
They are comfortable to wear. I like over the top of the head and not behind the neck models.
The Peltor models, I do like that don't cost much, comfortable, compact, and they work for me for hunting use:

Tactical 6 Electronic Hearing Protector
Mfr Part: 97044

They are simple and work without all the big dials, etc.
I have tried others $$$ brands made specifically for hunting.
The Peltors were better in my opinion for comfort, hearing amplification, and hearing protection value.
YMMV
