Gel pads seal around eyewear temples where foam gaps, the connectorized build hints at the comms platform it shares DNA with, and the 5X amplification ceiling out-hears most of the tier.

High gain is a tool, not a toy: run it at the minimum that restores awareness. Dead batteries fail safe to passive protection, but quiet muffs get pulled off — carry spares. Indoor ranges and magnum calibers push impulse peaks toward the top of the 140–165 dB band; run foam plugs underneath there.
