I think that's the point behind them. The low-profile muffs don't electronically reduce loud noises (over a certain dB rating) through witchcraft. They simply reduce noise like a set of regular earmuffs would. The battery power is used to drive the microphone to amplify faint noises like a rangemaster yelling at the guy next to you for shooting a hanger. Like I said, double-up with earplugs. Or, maybe, try a set of ProEars muffs and let the rest of us know if they're worth the extra money. I, for one, would like to know if they're a worthwhile investment.

Impact sports elctronic earmuff no good! (for me)[rant]

Respectfully I didn't ask you for the rating, I asked you if they reduce noise without the battery installed. I asked you that for a reason. To try to help you. How well do they reduce noise without batteries installed? If they cant do that they don't work as muffs, powered or not.
A blender is supposed to be louder when you amplify it that's how amplification works. All the electronic muffs allow noise below a threshold through, louder noises are louder than quiet noises that's normal. The noise reduction ONLY works above whatever threshold the factory sets.
Please understand I'm not trying to argue with you here, just help you to have a realistic expectation of how these work.

The NRR rating is OFF I believe, it says on the back of the box it goes up to 82dbs. Yes they do work without the batterys.
You have me completely confused now. "NRR" (Noise Reduction Rating) isn't a function its a rating for how much they reduce ambient noise. If I found the right info on your model it is 22dB I don't see how you can turn a rating OFF?
The 82dB you mention is probably the "clip point". What that means is the a the electronics don't cut off a sound unless it is higher than 82dB. I don't have noise ratings for blenders but I'll guess it is way below that point.
A quick search found this:http://www.howardleight.com/ear-muffs/impact-sport--2 model & it has slim line ear-cups, is this right? I had a problem with one model (not this one) where the interior of the cup contacted my earlobe & broke the seal, thus making them not work at all well. Can you feel the inside of the cups contacting your ear at all?

I'll throw in my 2 cents since I just got these as well. This is how I show them to others (and everyone is pretty impressed).
I put them on (someone else), turn it up, and show them how we can have a normal conversation and they can hear everything. Then I clap relatively near their ear. They are surprised how this ISN'T SUPER loud. No, it's not totally quiet, after all these are 22 NRR, not 31. But then they take them off and I clap the same distance and the same intensity. They're surprised how much louder it is.
So in this instance they worked perfectly, amplifying noise below a threshold. Once that threshold is met, they simply turn OFF amplification. If they're not turned on, the clap should = the same noise level with them turned on.
Edit: note at the range, I plan on doubling up with foam plugs since 22 NRR isn't going to cut it when the guy next to me is doing 44 mag (at an indoor range). For an outdoor range or hunting, i think these are awesome (plus they're easily compacted).

With mine turned up all the way, I can hear voices well, a plastic bag very good.
But when you turn something loud on like a blender, the thing makes them louder...copied from first page
Sounds like they workwell. sounds get LOUDER.
What happens when there is a loud bang (gunfire). Everything should shut down for a couple secs.
Changing batteries shouldnt make the shutdown (noise blocking) any better. That should work without batts.
