tells me there is no history of this kind of trouble, and if there is a

Time to replace my 20+ year old Telex headsets. Been looking
around and am interested in the Nav Data headset (
www.navdatakneeboard.com/index.html ). ANR is not necessary, as
I'll modify my headset to ANR if I feel I need it (Headsets Inc.).
So these seem like a pretty good choice. The price is right, and
judging by the information, they are a US company (Florida).
They are being sold at ACS, Tropicaero, The Pilot shop and
several other pilot supply stores.
But I can't find any reviews on them. Has anyone any experience
with them? Or know anyone who has?
Or opinions?

Harley,
At that price, I would be shocked if they were American made or of good
quality. All of the headsets in that price range seem to fall apart in
a few years with moderate use.
I'd recommend a David Clark 13.4. You can add ANR later, and those
headsets are absurdly sturdy. Of the five headsets I have, two are
David Clarks, they have more use than the other three headsets I have
but the DCs are the only ones that have never broken. My Lightspeed 15K
has been sent to Lightspeed several times and now they no longer make
several of the replacement parts, so next time it breaks I guess it goes
in the trash. If a David Clark headset does break you can send it to
them and they'll often fix it free of charge. On Ebay, nearly new 13.4s
go for less than $200. New they are less than $300.
My guess is that the NavData headset is just a re-badged cheap headset
from a foreign manufacturer. It looks identical to the "SHS880C", the
weight and noise reduction are identical to the 10th of an ounce. I
think the SHS is Korean made.
http://www.sadoun.com/Sat/Products/Aviation/SHS880C-Aviation-HeadSet.htm
My opinion...the cheap headset will cost you more than a sturdy David
Clark...and you have to deal with the inconvenience of it breaking when
you need it.

I find headsets to be the biggest marketing gimmick since spark plugs and sneakers.
Do you folks remember when we used the Mic? Ok, yes, they are comfy, cut
off important engine noises you should hear and sell lots of magazine advertising,
but for the poor sap that fly's 35 hours/year, one doesn't need a $300-$1000.00
set of ear muffs.
If it works, suits the mission and your ears don't look like cherries when you
get home, it's probably worth saving a few bucks or at least carrying as a spare.

I wonder if we took a survey, how many of those people now have hearing
loss?
$300 spent so that I can still hear when I get to retirement age seems
like a pretty good investment to me.
I can wear the $100 headset I have for about a half an hour before I
start getting a headache. I have worn my Bose headset for over 8 hours
in a day (two 4 hour flights, back to back with a small break in
between), and at the end of the day I still barely noticed it was there.
I consider the $950 Bose headset one of the best values I've made in
aviation purchases. I've been using them for about 8 years now, so
that's roughly $118 per year at present, with the cost decreasing and
the value received increasing every day.

Good Afternoon Dj,
I am afraid I am one of those who flew for well over fifty years without
using any ear protection.
I DO now have a considerable hearing loss.
About fifteen years ago, I bought Bose Headsets for my airplane. Just wish
I had started sooner!
Not only are my ears protected, I now comfortably communicate with my
passengers. Something that could only be done by shouting in years past.
A good set of noise canceling headsets is the cheapest, lightest, and most
efficient way to get a comfortable environment in any airplane. It beats
thick windshields and massive insulation. As you said. The noise canceling
headsets are not expensive, they are cheap when compared to other methods of
sound attenuation.
Happy Skies,
Old Bob

You've got that a little turned around. If you order the Rigol from
tequipment.net, it will ship directly from China, like mine did. Rigol
is a Chinese company, and makes decent products for people on a tight
budget. The only issue I had was the foreign power plug that came with
it. I substituted a spare US IEC cable (a computer power cord) and was
up and going quickly.
The DSO (which I've never used) may be made in China, but Sparkfun is
in Boulder, CO -- to the best of my knowledge everything they sell
ships from there.
Both sparkfun and tequipment.net are companies I've bought from in the past.

I belong to an Aviation club where the average membership age is 68.
Most of the members over 50 begin pursuit of hearing aids from the
flights back in the 60's & 70's.

Yes, but many of us lost our high frequency hearing courtesy of that
little distraction we had occupying the lives of high school graduates,
brought to us by Ike, JFK, LBJ and Tricky Dick. Flying was one of the
few pleasurable things we could do while waiting for the next set of
orders to proceed to the nearest flight across the Pacific. Only benefit
is VA providing the hearing aids gratis.
