The earcup is 1.1 inches thick at the cushion, with an angled cut-out at the front edge that follows a standard AR stock. Most shooters get a clean cheek weld without lifting their head. Bolt-action combs need no adjustment.

HushCore is rated NRR 22, realistic for any slim electronic muff at this price. Indoor ranges with high-pressure pistol calibers benefit from doubling up with foam plugs — that's standard practice with any electronic muff in the slim category.

The chip detects sound above 82 dB and attenuates the speakers in 0.01 seconds — about 10 milliseconds. Fast enough to catch a centerfire rifle report before the impulse hits your eardrum, while keeping the gate open between strings.

Two AAA alkalines power the electronics for roughly 350 hours of active use. For a shooter who hits the range once a week for 3 hours, that's about two years per battery change. Pull the batteries during long-term storage to prevent corrosion.

The foam ear cushions conform around the temple arms of standard prescription and shooting glasses without breaking the seal. Replaceable gel-foam upgrade pads are sold separately for shooters who need maximum sealing around thick eyewear frames.

Yes. The 3.5mm AUX input on the left earcup accepts any standard headphone cable. Plug in a phone for music between targets, a shot timer for dry-fire drills, or a two-way radio for hunting comms. The active mic system stays on at the same time.

The active gate triggers on any sound above 82 dB, so HushCore covers hunting (amplifies game footsteps, kills the muzzle blast), construction, lawn care, motorsports, and chainsaw work. Slim profile and AUX jack are bonuses outside shooting.

Yes. With dead batteries the electronics shut off and the earmuff falls back to passive NRR 22 from the foam-filled cup and gel pad. You lose ambient amplification and the active gate, but keep solid hearing protection until you swap in fresh AAAs.
