Hi, some information from the owners manual:
TECHNICAL INFORMATION
Microphone
(Electret)
Bias required: 8 to 16 VDC through 220 to
2200 ohms
Sensitivity: Varies depending upon bias and
radio AC input impedance. Typical output is
600 mV at 114 dB SPL. To assure proper
modulation of the radio, it is recommended
that an avionics technician adjust its input to
match the output of the microphone.
Microphone
(Dynamic)
Impedance: 5 ohms
Sensitivity: Equivalent to M-87/M-101
Cheers

rotorhead8, yes, the school owner could be correct, when you buy a Bose X you have a choice of two different microphones. The high impedance one is compatible with all R22s and most civilian helicopters. The low impedance one is used in military aircraft and some civilian versions of military helicopters.
Take the foam cover off the mic and have a look at the shape. The high impedance (electret) mic has a rounded, flattened shape, while the low impedance (dynamic) version is shaped like a light bulb.
If that is the problem then the solution is to purchase a high impedance microphone and replace the microphone, it's quite a straightforward operation. Or even better, take it back to where you bought it and ask for the correct mic!

KrisRamJ, that seems to be my problem! thanks for your help! i contacted the guy i got them from and he's gonna call bose for me tomorrow and see if they either have an adapter for it or if i can just exchange the electret mic for a dynamic.

The reason that the Zulu doesn't have a mic that swivels beyond 180 degrees is because
(a) it's a stereo headset with L & R cups
(b) the physical design is for the headset to be worn only one way
In which case, swiveling the mic beyond 180 would only be useful if you were talking out of your a**e.

who has tried the Nanocomm GA
I've been using a purtone nanocomm since last year fitted with a 'Helicopter' fitted jackplug. They have a web site "www.nanocommga/index.htm"
I got mine last year, and since I now wear specs I can't fault it. Good value.
I suggest you contact "Alistair at HearingHelp.eu" to answer any further questions. I'm sure he may be able to get you a better price too.

Lightspeed Mach 1 Headset
Hi all,
Sorry for yet another headset post, however I am thinking about buying one of these as a gift and would like to know if there are any issues with this headset. I have had a hunt around other threads and cannot find anything relevant.
The recipient is a S61 pilot who flies around 600+ hours a year and currently has a bog standard peltor as do the majority of the other pilots. How comfortable is it to wear with the custom ear seals? Does it interact well with the peltor (I know that some headset/intercom systems don't hit it off that well sometimes) and do I have to order a specific microphone impedence type?
Thanks in advance

Im sorry to sound rude but do you have any idea about aviation and headsets? Your option of a mach 1 Mach-1 Is totally inappropriate for a helicopter. You need to choose a headset with a fully enclosed ear on both sides, and prefferrably WITH ANR (Active Noise Reduction).
I am assuming its for a BIH pilot in penzance/Falklands, and as such you need to check their impedance as there is two types (low/High). I am fairly sure it's low impedance like our S61's.
I can highly recomend the Lightspeed Zulu as I use it now and have flown the S61 previously for 5 years and I would have loved to have used it then.
Si
P.S. I wish I had friends as generous as you.

The Mach 1 is entirely appropriate for a helicopter. I tried that model, and while I eventually bought a Clarity Aloft, it worked fine. I just didn't like the earplugs that come with it as much as the Comply tips on the Clarity Aloft, as well as the overall design. Lightweight in-the-ear headsets are perfect for helicopters, because they provide better noise suppression than conventional headsets, and are much more comfortable after hours in the cockpit. Of the models I know about, the Clarity Aloft and Quiet Technologies are pretty much comparable, although the Clarity Aloft has slightly better build quality along with a higher price. The Mach 1 is in third place, although not that far behind. This ranking is entirely subjective and entirely my own, and I've seen reviews that rate the Mach 1 highest. It's mostly a matter of personal preference. I'll certainly never buy another conventional headset, either passive or ANR.
Have both use Pilot PA17-79 DNC XL I find these good, tried Bose (did not like them, small ear cups big ears)
Also use the Mach 1 "with custom inserts" are the DBs for longer flights (could not get on with standard bits supplied) & if you can get use to the ear moulds, some people find them really uncomfortable.
Don't think they do single plug or low impedance Mach 1, make inquires.
Not tried Clarity or QT but GP really likes them
Also remember ANR does not protect the ear as well as inserts

You won't find a low-impedance model, nor a U174 plug. You can get an adapter, or convert the plugs, either way works. Low-impedance headsets are rare in the US, only the military uses them very much. If you need an in-the-ear low-impedance headset, contact Quiet Technologies. The owner was very helpful in getting mine set up properly. He may be able to provide a low-impedance model.

Headset / mic impedance conversion...
So, this old chestnut again...
I have a standard high-impedance GA helicopter headset with ANR. I'm shortly due to be flying an aircraft with (what I believe is) a low-impedance system; the stock headsets it comes with are nasty passives. I'd like to use my whizzy ANR set (complete with all my own drool on the mic sock), so I'm exploring options.
My headset is a Lightspeed Zulu, in the standard helicopter fit (U/174 plug, ANR, battery box - Zulu:C configuration). The mic spec is a 'noise-cancelling electret' with an impedance of 220-2200 ohm (according to the manual). Lightspeed's suggestion is that I convert it to a low-impedance mic (which they will do for me), then use an adaptor to get it up to high-impedance for when I'm in a high-impedance aircraft, such as this one: Buy Pilot Products JB-23H Low to High Impedance Adapter for use in Rotor Wing applications- Sky Geek, Skygeek Pilot, Pilot Supplies, Military Headset Adapters, .
I've had a look around, and I've come across a converter from high to low (e.g. High to Low Impedance Adapter (Helicopter) - MyPilotStore.com ). It seems to me that this might be a simpler solution, since it doesn't involve me posting my headset to the USA for conversion. Is there some disadvantage to this route that I'm not seeing?
The main drawbacks of converting a high-Z headset to low-Z, instead of a low-Z headset to high-Z, appear to be that I need batteries in the converter (the low-Z mic to high-Z system cable doesn't seem to need them). Also, since I guess there are a load more military headsets floating around which are low-Z, which need converting to high-Z for use in civvy helicopters, this conversion is better understood and supported.
Has anyone used a high-Z headset to low-Z aircraft converter? Did it work? Can anyone point out any advantages of low-Z mic --> high-Z aircraft over high-Z mic --> low-Z aircraft?
Any info / pointers appreciated
Edited to add: I'm aware of this thread: http://www.pprune.org/rotorheads/431...-matching.html which didn't really answer the same question. I am also aware of the DC headset which includes switchable impedance, and I'm not mad keen to be buying another headset right now. I've contacted Headset Services at Shoreham, and their response was "no idea, we don't deal with Lightspeed".

Lightspeed Zulus
So I just picked up a set at heli-expo. So far I love them they seem to have the same sound quality as the Bose without the extra price. However, I can't say much about them for I just got them. My question do any of you guys use then? And if so what are there short falls if any? Just want to hear for someone that's not a salesman

HEADSET MISERY
I purchased a "helicopter" NC headset from LIGHTSPEED. It was a ZULU 2.
DONT BUY ANY PRODUCTS FROM THIS COMPANY. I sent the headset in 2 times, once to get the mic changed as the "helicopter" headset I purchased did not work on the helicopter I am flying. (low impedance). Had them change the mic from high to low and it still did not work. Sent it back again since the mic boom fell apart with out the wind cover. I hoped to sell the thing so I had them replace it with the high impedance mic. The damned thing still doesn't work. So I have a very expensive headset that I can only use for listening to music. There is nothing they can do.
DONT BUY A ZULU HEADSET PERIOD.
