I wouldn't recommend for indoor range use - Pro Ears Pro Tac Slim Gold NRR 28 Hearing Protectors

Sturdily built and comfortable to wear but very crude industrial design. The intra ear cup foam sliver that covers the battery and electronics are flimsy and not confidence-inspiring. The "+ -" markings inside the battery cradles are frustratingly difficult to see and installing the batteries lack a definitive "click." Volume knobs seem unnecessarily proud of ear cup surface for bare hands and have overly generous travel from min-max. Subtle detents would help user intuitively adjust both ears to same level quickly.

These hearing protectors seem adept at conveying speech clearly while reducing gunshot noise - just not enough for indoor ranges.
