OPSMEN M30 Hearing Protectors Ear Muffs for Shooting and Hunting (NRR 22)

I have been using mine for a few weeks now and like them. They are lightweight, comfortable, simple to use (only one on/off volume rheostat control), easy to change batteries, and work well. Each side attenuates loud sound independently which is a really nice feature. I usually wear mine over a cap and still get a decent seal. They hold in place with sufficient side pressure to maintain the seal without being so tight as to put too much pressure against the head. Sound quality is decent. Maximum sound volume appears to be equivalent or slightly louder than ambient sound levels without the muffs. Each muff has its own microphone and so sound is stereophonic, and as noted, each muff attenuates loud noise individually. I use my muffs while hunting and while at the gun range.
