Shooting Ear Muffs

Planning on getting my dad some for Christmas, I use a set of impact sport electronic ones but do find they really pick up Cicadas and feel they could be better.
I use mine mainly for range shooting and a bit of hunting but he will really only use them for duck shooting.
Am leaning towards the peltor protac hunters but after any experience or recommendations before I push the button.

I think they might be the flasher model, are they Bluetooth?
They seem like they have a bit more of a scallop towards the bottom of the shell which could help cheek weld a bit

I have a pair only issue I have is creeks and streams that without muffs you cant hear so pretty loud.
Otherwise good
