Digital model produces crisp, clear sound and a faster “attack” time. Sound-Activated Compression shuts off amplification for sounds above 85db, and the muffs deliver an NRR of 24db. Fine-tune the sound to a wide variety of situations like the hunting woods or the shooting range using the Adjustable Frequency Tuning and independent volume control. Ergonomic headband and rubber ear seal ensure a comfortable fit. Requires two 1.5V N-cell batteries (included). Accoustically designed low-profile cup. Available: Analog, Digital. Colors: Green, Camo.
