1 minor flaw - changing batteries - 3M Peltor 6S Tactical Hearing Protection Ear Muffs

I've had mine for almost a year. I've used them for Pistol, rifle & shotgun.
1st the Pro's -> 1. These do not "amplify" the sound like others will, just enough for normal conversation, therefore you don't get that constant pinging echo you get with the others at indoor ranges, or at a Booth Type pistol/rifle range. I've had it do that once and just turned it down some. Others I've had to turn off & I added inner ear protection.
2. Behind the head/neck band works great. I really prefer this type now that I've used it.
3. individual volume control - best part of this is-IF they get turned on in the bag, 50/50 you'll still have one ear with a mic.

Now the CON -> 1. minor, but some like the "Amplified" earmuffs for hunting due to the increased volume to hear little critters far away - These will not do that (at least mine won't)
2. It seems to me the "Slim side" of the muff, should be the down side for rifle or shotgun - they bother me when they hit the stock, so I flip them upside down -band behind my head, not the neck. U-Tube Video tells how to fix that - same video on how to change the batteries !
3. What a Pain in the fingers to change batteries ! You feel like your trying to Break Them apart! No directions came with mine - luckily a fellow range worker had a pair just like these. Easy way -Per a You Tube Video - Use a Screwdriver to Pry them apart ! & to pop the batteries out.
4. - These take up a lot of room in the range bag - they do not snap together and collapse like several over-the- head band type do, and movement can cause one side to turn on > spare batteries and screwdriver!

All this said - I still like these better than over the head band types, especially in the summer - to a point. IF conversation is not necessary, I still prefer inner ear protection, especially with a long gun.
