Overview
The EARMOR M300L is a passive folding earmuff from EARMOR, a brand known for electronic and passive hearing protection for shooters, hunters and professionals. It has no electronics and no batteries to fail, so it works the moment you put it on. The cups are black with a grey panel and yellow trim, which makes it easy to spot on a bench or in a range bag.
The headband is padded and covered in soft black fabric, and the cups are fitted to a folding wire frame. When folded, the muffs collapse into a compact block that slips into a pouch, range bag or glove box. That makes them a practical spare pair for a second shooter, a guest at the range or a range officer.
This is the passive model in the lineup. It is simpler and cheaper than the electronic EARMOR muffs, which amplify quiet sounds and cut off loud ones. Here you get steady, constant attenuation. The Noise Reduction Rating is listed as 27 dB for this listing.
Key Features
- Passive design with no batteries, so there is nothing to charge, replace or switch on before you shoot.
- Folding frame that collapses the muffs into a compact shape for a bag or pocket.
- Padded fabric headband that spreads the weight over the crown and stays comfortable over a long session.
- Adjustable headband arms slide to match different head sizes.
- Foam-lined cups with soft ear seals that close around the ear and reduce the gap noise can leak through.
- High-visibility black, grey and yellow styling that is easy to find on a crowded firing line.

Fit & Sizing
The headband arms slide in and out of the cups, so you can set the cup height to sit squarely over your ears. Adjust them until the seals sit flat against the head with no gaps. Hair, glasses arms and hats under the seal all let sound through, so shooters who wear glasses should check the seal after fitting. The padded band spreads the clamping force, which makes the muffs more comfortable over a long day at the range.
Who It's For
These muffs suit range visitors, new shooters, hunters who want a spare pair, and anyone mowing, drilling or using power tools. They are a good back-up in the safe or vehicle, and a sensible way to equip guests. For the best protection on a firing line, many shooters wear foam plugs under passive muffs. Shooters who want to hear range commands clearly in between shots may prefer an electronic model.
Care & Maintenance
Wipe the shells and ear seals with a damp cloth and mild soap, and let them dry before folding. Keep the muffs out of a hot vehicle, because heat can harden the seals. Replace the seals or the whole set if they crack, compress or go stiff, since a damaged seal lets sound in and cuts the protection you get.
