Description
Product Details

Bionic Hearing and Lightning-Fast Protection:
At the heart of the Earmor M300A beats a high-precision environmental detection system. The integrated microphones capture the surrounding sound spectrum at 360 degrees, allowing you to maintain perfect "Situational Awareness": you will hear the range officer's instructions or the movements of opponents in the woods with crystal clarity. But as soon as a shot occurs (or a harmful noise above 82 Decibels), the electronic circuit intervenes in less than a millisecond, cutting off the sound and protecting your eardrums flawlessly.

Operational Ergonomics (Single Knob):
In stressful situations or when wearing heavy tactical gloves, searching for microscopic buttons is frustrating. Earmor has revolutionized the user interface of the M300A by equipping them with a single continuously variable knob. With a single fluid and intuitive movement, you can turn on the device and adjust the volume of the ambient amplification. The foldable and adjustable headband adapts to any operator, making them very comfortable to carry in your bag and ready to use in a fraction of a second.

Main Advantages

Superior Isolation: NRR value of 23 dB for excellent passive protection.

All-Weather (IPX5): Certified to withstand water jets and heavy rain.

Pro Tips

Model A or Model T? Let's clarify! The Earmor 300 series exists in two versions. This is the M300A (Active) model, and it is a pure electronic headset, WITHOUT Bluetooth. It is perfect for shooting purists who want to isolate themselves from the digital world, save battery and have a slightly higher level of passive protection (23 dB). If you are looking for the model to connect your phone and listen to music, look for the "M300T" in our catalog!

The salvation of Auto-off: How many times have you returned tired from a game or from the shooting range, thrown your headphones in your bag forgetting to turn them on, and the following Sunday you found yourself with completely discharged batteries? With the M300A this nightmare is over. The intelligent system will detect inactivity and completely turn off the headphones after 4 hours, saving you battery (and the next game day!).

Comfort in the rain: Unlike many competing models that fear humidity, the IPX5 certification of these headphones allows you to continue your outdoor training even in a sudden downpour. The internal circuits and microphones are sealed: you no longer have to run away to hide your equipment from the first drops of water!
