OPSMEN Earmor M31 Review

with No Comments

Retailing at around $49, these headsets are about the same price as Walker Razors and Howard Leight Impact Sports. They have been supplied for this review by Opsman and Evike.com and I found them to have the best features of both the Razors and Leights; the directional stereo sound of the Howard Leights and the superior AUX audio sound or Razors (actually a bit better audio than Razor).

One sore point (literally) was that the extra-soft earpads didn’t provide sufficient spacing for my ears. They would pinch against the inside of the earcups and became uncomfortable after about 30 minutes of wearing. I replaced the foam pads with supplied gel pads which relieves the issue slightly. I suggested a larger plastic frame spacer to the OPSMEN, or simply thicker pads. I hope they offer this as an option soon.

These low profile Electronic Hearing Protectors feature a noise reduction rating of 22 decibels. 2 x AAA batteries power the unit for up to 350hrs. And if you forget to turn off the unit before putting them away, it has an auto-shutoff after 4hrs. 

They’re reminiscent of MSA Sordins combat headsets but with an unusual asymmetrical slant. They’re designed with this angle so that the earcup rests against your rifle stock. It’s an effective design solution to the problem of noise leak due to a pushed earcup when you’re using iron sights.

Walker’s Razor vs Howard Leight Impact Sport

with No Comments

I can’t stress enough how important ear-pro is. Use any legitimate hearing protection when firing your firearms. Electronic ear protection is a leap in functionality from simple ear plugs and standard earmuffs.

Bear in mind, electronic earmuffs but they can sometimes be advertised as electronic noise-canceling earmuffs. This should not be confused with Active Noise Canceling headphones used to listen to music (Bose, Sony, Beats, etc.) Those work by creating mirror sounds that cancel the offending background droning sounds like an air conditioner or jet engine. Those music headphones can NOT be used for gun sports.

Electronic Earmuffs work by passive noise reduction like non-electronic earmuffs; by simply blocking loud noises with the sound-deadening insulation. The electronics instead pipe in ambient sounds from outside the earmuffs, until a noise exceeds 82dB; they electronically shut-off the mics in an instant. Both reduce loud noises, reducing gunshot sounds (approx 155db) by about 22 decibels (dB) to approximately 133dB. Their Noise Reduction Rating (NRR) is the amount of decibel noise reduction they offer.
