Ear Plugs vs Muffs

Anybody have a brand of electronic ear muffs that are USB rechargeable or just rechargeable? Mine uses AAA and they don’t last long.

I usually use both. Habit from my NRA high power days. Want max hearing protection when on a firing line, but I used electronic muffs so that I could hear the commands from the range officer.

Why not just get rechargeable AAA batteries?
