Earmor Passive Hearing Protection M300L

Earmor M300L Passive Earmuffs (Black)

The Earmor M300L is a passive earmuff without electronics. Sound insulation is purely physical, achieved through a multi-layered construction and sound-absorbing foam – without batteries or active components.

With a noise reduction rating (NRR) of 27dB, the M300L is suitable for use at the shooting range, hunting, and training. Its foldable design and adjustable headband make it compact for transport in your range bag.

Multi-Layer Sound Insulation:

The M300L uses sound-absorbing foam with densely packed pores to effectively absorb noise energy. A centrally located damping ring reduces structural resonances within the earmuff, and the multi-layered construction progressively dampens noise across the frequency spectrum.

Comfort and Fit:

The soft foam cushions seal around the head, ensuring comfortable wear even during longer training sessions. The adjustable headband adapts to various head sizes.

Foldable Design:

The M300L can be folded compactly, fitting easily into a range bag, backpack, or shooting case.
