I assume that if the electronics are not turned on, these act exactly like standard earmuff hearing protectors, correct ?

Correct, if they are turned on, they are active earmuffs meaning you hear around you. Off and they act as passive style meaning everything is cancelled out. So far these work fairly well, unless you are at a very busy range, where someone is shooting every second, they will cancel out all the shots basically making these passive even when on.

That is correct, they work fine as standard earmuffs without the electronics turned on

The turn knob on the rear of the right ear protector controls the on/off as well as the volume of the built-in microphones. When this in turned off, they will work as non-electric earmuffs which are rated at 23 NNR.

I am not sure if they are like standard earmuff hearing protectors. These are the first one's I have ever purchased. I can tell you they work very well. We wear them in our side by side and can hear each other well.

Definitely. Playing something is not necessary to make the electronic noise cancelling work. However, as I said in my review, the electronic noise cancelling on these headphones is minimal anyway - barely noticeable. But the padding/baffling on these over-the-ear phones is so effective that even without the electronic noise cancelling turned off, these phones are quieter than my on-the-ear Maxell NC III phones , which have pretty effective electronic noise cancelling.

No, but they do shut out at least a good two thirds of external noise, so it's wrong to use them when you need to be aware of outside sounds.

Yes, but must be powered on for them to work. There is no "pass -thru" use without noise cancelling. They work fairly well.

They seal quite well so they passively cancel. There are no active electronics. I fly frequently and they do a good job. I hope this helps.

Yes. Unless the hearing has an on-off switch (which most do not) batteries should be removed to avoid wasting batteries.

I would think yes. Cheap, so no worries if lost. If they don't mind piece in ear should be good. If they do mind, more ear muff like protection might be good

Yes, this meets OSHA standards. The big advantage is for burst noise. When noise is low, the amplifiers negate the damping of the muffs. They can even enhance hearing. Think hearing aide. But during a blast, they turn off electronics and are quiet. As I recal, about 26 db of noise reduction. Peltor has other models without electronics for areas of continuous noise which are cheaper. I saw a version with electronics at Lowes for $59. I really like these.

No, not electonically. Only by the nature of their being over the ear which muffles some outside noise.

They are sturdy as any hearing protection ear muffs. However, they do fit tightly (as they should to work properly). I start to want to take them off after four hours, so it is hard to imagine sleeping with them on.

If the batteries die or you leave them on and forget(as I have done) They will function as regular ear protection but they will lose the ability to amplify regular sounds. Basically the best part about these is the ability to hold normal or even whispered conversation and hear really quiet noises such as twigs breaking or footsteps in the snow. To restate my answer they would be great ear pro even if they were dead- Chris

Yes; I have to turn on both the base and the earphone. They don't come on automatically but no problem.

I'm not sure if noise isolation is the same as hearing protection, but I do use them when operating my riding lawnmower and my gas chainsaw, and that sound is minimized to where I can hear and enjoy music from my ipod. When the music is not playing the sound is lessened so much that many times I have to pull out 1 plug so I can tell when the chainsaw/mower starts so I can adjust the choke to complete the start.

Yes...my wife snores pretty bad and this is exactly why I bought them. They work well. What I like most about them is that I can still hear the alarm clock or a smoke detector or even a loud voice and such but everything is muffled to the point that it is not disturbing.

No, the headphones were completely dead when I received them. I plugged them in for a test and they worked. The headphones will work with the audio cable when the power is off. I just tried this out.

There is no electronic noise cancelling capability, no. They do fit the ear canal well, however, so they cancel noise the same way a pair of earplugs would.

I'm sure these would work for that particular purpose. However, you could probably achieve the same (if not better) results with some simple ear plugs. I use these when shooting as a second form of protection (I also use plugs). I say that to let you know I've never used just the earmuffs by themselves. In that regard, I'm a bit hesitant to say emphatically that these would work well for your proposed purpose.
