I have no idea if they are any good, but this Friday CompUSA has a sale on
them.

They are $55 on sale for $20. They look like Aiwa brand but I can't be sure.
I'm going to try a pair and see how they are if they don't only have 3 per
store and sell out. You know how these loss leaders go.

They cancel audio room noise, not received input noise, in case anybody is
unclear on this.

Say leaf-blower noise from the neighbor, or the dishwasher running, or
computer fans.

Mostly they cancel some of it, not all of it.

I use a pair of Bose noise-cancelling headphones, less cord just the phones,
mowing the lawn; or used to before I went to a scythe, which is more
entertaining.

http://scythesupply.com if anybody's interested in that possible hobby.
Every nice day, take a break from inside the house and cut a couple of
12' wide swaths down the lawn. In a few days, the lawn is done, and it's
time to start over.

(Noise-cancelling headphones can't deal with _really_ loud noise, like
gunshots, because they'd overload; unlike say earplugs)

Hmmm...I will admit I thought they did both.
Keep noise out and filter the input somewhat.
Thanks for the heads up Ron. I may not look at them now unless I get bored.

Yes, I was the original poster on this because I KNEW that they only read
outside sound and cancel it and are specifically designed NOT to interfere
with input sound but Iwas astounded when I trued them with shortwave radios
and found that they do somehow block out some of the background noise which
comes in through the ether??

It's a bit scary if they DO do this because it implies that they will
interfere with some frequencies in an audio signal which their manufacturers
(except Bose) strenuously deny that they do. I suppose it is all a matter
of experimentaion with different manufacturers. (Bose emphasises technical
proficiency, build quality and above all, marketing, over sound).

I remember when they started to be produced (initially for airplane use)
there was a heated discussion on some group or other about whether you need
LOW or HIGH freq blocking to get rid of jet noise.

This was supposed to be the difference between the original NC headphone
made by the company in Hauppauge LI which invented them in the commercial
marketing sense: I seem to remember they blocked low freq roar. For High
freq blocking you went to the Sony NCs, I think it was. The other course was
to fool the ear into thinking that you are geting blocking by expanding
dynamic range at certain freqs while selectively blocking certain
frequencies and increasing volume on others (this is what the Bose ones do).

Why am I getting visions of a 'Father Time' sort trimming the lawn?
The weirdest I've seen in real life was over a friends house some
years ago. They lived on a steeply sloped lot, making mowing very
difficult. In a moment of enlightenment, they bought a GOAT to graze
the grass. Everything went well until the poor creature got very sick
and started leaving obnoxious smelling droppings/sprayings all over.

That ended the experiment very quickly. The goat was returned to the
farm, where it lived out it's it's normal and happy goatish life.

You're not exactly harvesting the lawn, just cutting it back. There's no
question a full scythe looks cool.

The 3' grass blade is my favorite, but only works on a straight snath, and when
the grass it not too dry; the 26" is better all around, with a bent snath. Once
you're into it, you get them all. The pleasure is in looking for the perfect
stand of grass, that falls over completely when just touched by the razor-sharp
blade.

There are at various times and conditions approaches to this, which is what you
watch for.

I'm not sure father time was much into that.

Part of the ritual is wheting the blade every five minutes or so, and peening the
edge every few days, to get it paper thin again.

Otherwise you don't get your fix of stretches of perfect grass cutting.

It's nice to see such care, attention and learning being put into an
activity most of us don't know much about. Well..I have the 'aversion'
part sorta figured out and I *usually* cut away from the electric
cord. Now, due partly to that, I know greatness when I see it.

No, I dont know what they a I do know that I have the original ones
(called Noisebuster Extreme) which seem to have this effect for SW and are
generally OK for aircrsft use and some Sony ones which are even better for
aircraft use and have absolutley no SW effect at all. (Haven't tried the
Bose ones on SW or aircraft)
