Produkt-Highlights

  • Electronic hearing protection with 22 dB noise reduction
  • Up to 60 hours of battery life with auto-shutdown
  • Lightweight, foldable design weighing only 295 g

The Earmor M300A is a slim, lightweight, and powerful electronic hearing protector that offers reliable protection in noisy environments. With a Noise Reduction Rating (NRR) of 22 dB, it effectively protects your hearing from harmful continuous and impulse noise. Digital signal processing (DSP) reduces disruptive noise while clearly amplifying ambient sounds and ensuring voices remain easily audible.

The compact headset weighs only 295 g , making it significantly lighter than many comparable models. The multi-layered headband construction , made of foam, breathable mesh, and leather, ensures a high level of comfort, even over extended periods. Its foldable design makes the M300A easy to transport and store.

Operation is intuitive via a rotary dial that combines on/off and volume control. The hearing protection reacts to noise peaks above 82 dB in less than 1 millisecond, reliably protecting your hearing while maintaining clear acoustic perception. With a battery life of up to 60 hours and automatic shut-off after 4 hours of inactivity, the M300A is a durable companion for shooting sports, hunting, crafts, or professional use.
