Craig,
I have the Lightspeed 20 XL's as well as the DC anr's (cant recall the
number). I used to like the Lightspeeds untill I installed a new intercom in
my CJ. I have to turn the radio full up to hear anything as opposed to the
DC's. The construction of the Lightspeeds are flimsy and the factory support
wasnt the greatest. I thought something had gone wrong with the headsets
since I couldnt hear very well in them, so I sent them in, they said they
couldnt find anything wrong so they just sent them back, they did put on new
ear cushons at no charge, but the werent glued on very well. Another problem
I had with them was before I changed intercoms in my CJ, I had single plug
military jack for the headsets, so I bought a 2-1 plug adapter. The
lightspeeds use cheap steel jacks that wouldnt work with the adapters, any
other headsets worked fine with the adapters.
When I spoke with the intercom people, thingking there may be a
compatibility problem they told me that, their high noise intercom requires
a good headset, theres no point in a headset if you have to turn the volume
up to shock volume to hear anything. The poor passive attenuation of the
headsets still creates a high noise envionment in your ears, minus the low
frequencies canceled by the ANR. As soon as I switched to the DC's I was
able to turn the volume down 25%. The new intercom was designed with low
gain in order to avoid people substituting 102DB's of engine noise with 102
DB's of Com Noise. My helmet works really bad now in the CJ, since I
installed the new intercom. I bought the Oregon Aero kit and it made matters
worse.
Most people rave about the lightspeeds as I did, when used in a low noise
environment like the cockpit of a spam can. But their poor passive
attenuation renders them useless in a high noise environment. And you'll
never know it untill you install a good intercom that doesnt let you mask
out cabin noise with high radio noise.

I have no experience of ANR whatsoever, but am a prospective buyer. There
was an IAC offer recently for the Stratus, which I almost bought, but keep
being dazzled by the input jack on the lightspeeds, that one can connect a
phone and /or audio player to. This I really fancy, for use in long trips
in spam cans as well. So ultimately I want the lightspeed 30g, but am
reticent to purchase in case it doesn't work well. So Aubrey, you have not
had any of the problems in the Yak52 that the other guys mention? OK with
someone in the rear as well?

This is a re-edit and repost of a message I sent to the Yak List on August
7, 2003:
Lightspeeds:
Earlier LightSPEED headsets had some design
details that led to cracking of the stirrups and headbands. However,
any headset from the XL series forward has had those items improved to
stop the cracking. If you've ever talked to LightSPEED on the phone you
will see that they are more than willing to repair or replace most any
headset for you at no cost, despite the age or warranty status of the
unit. Outstanding customer support. They will also give you the option
of sending your unit in for them to do the repairs or if you so desire
they will send you the improved parts so that you can do the repair in
the field (I did this on the stirrups due to an upcoming trip timing).
One irritating item on the Lightspeeds are their mic booms. They tend to
twist the microphone from optimum alignment and take some getting used to.
The reason I found not to use the LightSPEEDs in the CJ were due to
their noise canceling circuitry. Especially the higher-dollar 25XL or
30. They try so hard to actively suppress the noise that you can start
to get choppy feedback due to their sensitivity. The more you pay the worse
it gets with Lightspeeds. To their credit Lightspeed admited to the problem
in very noisy conditions.
I found this not to be
the case with Denali ANRs, Telex Echelon ANR's, and Bose X. I also
found that switching my CJ intercom out for a PM1000 high-noise version
helped the problem.
However, I do use LightSPEEDs exclusively for the Piper
Comanche because they really seem to be in their element there with
unsurpassed comfort and stereo fidelity.
Based on the different headsets I own I would rate them as follows (in
order of preference):
LightSPEEDs - I own 3. Best all-around headset but only seem to work in
a CJ with high-noise ICS like PM1000 or Sigtronics. Uses two AA
batteries (most common). LightSPEEDs have a very thick headband and are not
good if canopy clearance is an issue.
Bose X - I have access to 1. Wonderful all-around headsets that cost too
damn
much (their only real negative). The one I have access to is not mine
so I don't use it much. These are something you would never leave in
the cockpit and would always take home with you at night.
Telex Echelon 150 ANR - I own 1. Great headset with ponderous separate
battery box. Not as comfortable or quiet as the Lightspeeds but very
functional in a CJ right out of the box. Awesome microphone and boom
effortlessly adjusts. Rugged metal construction and
seemingly high-quality components. Uses 9v transistor battery. I
always use this one in the CJ. Based on this unit were I to buy a new
headset of any kind it would probably be the Telex Stratus (although it
seems to be as thick on top as a LightSPEEED).
Flightcom Denali ANR - I own 2. The least amount of noise passive
protection and a little floppy on the head and sometimes "unport" their seal
when moving your head. Seem adequate with
electronics turned on. They also use a 9v transistor battery. Very light.
Flightcom Denali Passive - I own 1. One step up from using a cabin
speaker. No meaningful passive protection. Good to give away to
somebody you don't like.
I suppose if I needed a unit to install into a traditional helmet (i.e.
traditional
construction with metal stirrups) I might investigate a Flightcom 5DX
ANR or one of the David Clark models.
As mentioned before, my new target as a hands-down winner would be the Telex
Stratus 50-D.

I have tried three brands DC, DRE 6000, and Bose. The Bose are nice but priced
totally out of line. The DRE 6000 is a good unit and reasonably priced. The
DC 13.4 ENC (with 9 V battery) work great really do drop the noise level with
the electronics on.
When I was looking at head sets in the store I tried the Lightspeed 25XL and noticed
that I could hear the background music in the store, not good passive attenuation.
I have also noticed that the Sigtronics SP 400N intercom is sensitive to the quality
of headset used and also does not like different headsets at the same time.

OK Yakkers,
You really need to look into DRE 6000 headsets. ANR headsets for under $280
each. They have the best attenuation (-29dB) of any headset. I use them when
not using my HGU-68 helmet. Oregon Aero has ear seals for them also if you
wish for additional comfort. They can be found on the web:
http://www.drecomm.com/prodsvs.htm
or direct: sales@drecomm.com
They have just designed a new military version DRE-6000m and DRE-6500M. Both
are Consumer Avionics "best buy" of 2003. Look them up. The owners name is
Rod De Reyes. His stereo intercoms are standard equipment in the new YAK
52TW if stereo is requested. He knows YAKs and the noise environment.
Good luck

I use the Bose headsets but the down side is the battery replacement with
the higher noise level in the 52.
Pricy but I have seen a few on ebay at half the cost!!

I have two Lightspeed 25XL headsets. I have used them in the CJ and in my
spam cans. I would like to reitterate some of Ernie's findings.
1. These headsets have less passive attenuation and are probably not the
best for a high-noise environment.
2. The mics that Lightspeed provides do not do a good job of canceling
out cockpit noise. The Intercom then pipes the noise back into the
headset and out on the comm radio. You are better off looking for a
headset that has a really good noise-canceling mic or retrofitting a good
noise-canceling mic.
3. My first 25XL has suffered three physical failures, i.e. two yoke
failures and one headband failure, and one electrical failure, i.e. the
battery box. Support from Lightspeed was good and they never charged me
for any replacment parts.
4. Both headsets have now developed problems which will require that they
be returned to the manufacturer.
Alternatively, their low-cost headset with the passive attenuation only is
very good and very quiet. This has become my preferred headset in my
Comanche in spite of having to resolder a wire in the volume control
module.
Bottom line: I will not buy Lightspeed ANR headsets again.
As for Ernie's comment on the helmet, my HGU-33 with the Oregon Areo
fit-kit provides excellent passive noise attenuation and comfort.

If you "civilianized" a military helmet without changing the earspeakers
you might get low audio level. Most people know to change the mic (US
military uses a high-impedance dynamic mic while civilian headsets use a
low-impedance carbon, amplified dynamic, or electret mic) but not
everyone knows that the military earspeakers are low-impedance (8 ohm)
while civil earspeakers are high-impedance (600 ohm). The result is
that the military earspeakers will overload many radios or intercoms
resulting in low audio. You can fix the problem with a small 600 ohm to
8 ohm matching transformer.
> Experiences?
Flight Suits Ltd. has an ANR kit for most helmets. They are probably
OEM-ing it from someone else but from where I don't know.

I have the headsets,inc ANR kit in a Dave Clark, and also a LightSpeed 15XL
and HGU-55. Headsets has a kit for the HGU which, basedd on my experience
with the DC should work quite well. (and cost $169)...

Theres an ANR kit for helmets from a company called Headsets inc. I
think it costs about $169.00 and I heard it works rather well.

If you "civilianized" a military helmet without changing the earspeakers
you might get low audio level. Most people know to change the mic (US
military uses a high-impedance dynamic mic while civilian headsets use a
low-impedance carbon, amplified dynamic, or electret mic) but not
everyone knows that the military earspeakers are low-impedance (8 ohm)
while civil earspeakers are high-impedance (600 ohm). The result is
that the military earspeakers will overload many radios or intercoms
resulting in low audio. You can fix the problem with a small 600 ohm to
8 ohm matching transformer.

Flight Suits Ltd. has an ANR kit for most helmets. They are probably
OEM-ing it from someone else but from where I don't know.

Folks,
If you have broadband (works with 56K as well), a flash artist has put up some
art on the public web pages of the site under aircraft, events, news etc. Maybe
too many moving aircraft, but it's temporary (nice looking work though!!).
We are working through the new database issues, we are working in the stone age
as we have to update you folks manually - e-mail me off list if you have renewed
(are current) and are having difficulties loggin in, it only takes a few seconds
to update your information. And for now, just use your last name for login
fields
A member from Florida is setting up a database that will update automatically -
what a guy!

Just looked at www.headsetsinc.com
Rhe helmet upgrade kit (M-03-A) cost is $179 with foam earseals, $199 with
gel. it appears to have everythinh needed to civilianise your helmet,
except perhaps a mic.

Get the Oregon Aero ear-seal kit if it will fit. It will be much more
comfortable. (Heck, get their whole helmet fit-kit.) You probably want
the Sigtronics noise-canceling mic. I think Doug can get that for you.

Here's a dumb Newbie question for the pros.
What's the SOP on an oil change on a stock CJ? There appears to be a tube
that prevents the entire contents of the oil tank to drain out?
Thanks,
Jay

There is a valve in the inlet oil screen housing that allows removal and
inspection of the screen without draining the oil from the tank.
To drain the oil just open the tap, when it is finished draining remove the
screen assy.
Cheers
