Earmor M‑300A headset delivers professional-grade electronic hearing protection, built to suppress harmful sound impulses like gunshots while amplifying softer ambient noise for maximum situational awareness. Thanks to advanced DSP (digital signal processing), it can reduce impulsive sounds above 82 dB in under 1 millisecond, all while keeping communications and environmental cues clear.
With a lightweight design at around 295 g, the headset is tuned for long hours of use without straining the head. The soft earcups and adjustable metal headband offer durable comfort, and its foldable structure makes it easy to transport or store. The intuitive rotary control knob combines on/off and volume settings in one, ensuring rapid adjustment even with gloves on.
Powered by two AAA batteries, the M‑300A can deliver up to ~60 hours of operation, making it reliable for extended sessions. Its rugged build includes IPX5 water resistance and a robust structure ideal for shooting ranges, tactical training or industrial environments.
