Thanks for that link to Skygeek, but the description of part # USA PA-87H is confusing.
In the title is says will convert a high impedance mic (Lightspeed Zulu for example) to use in a low impedance aircraft. But when you click on "view details" it says:
Allows military low impedance headsets equipped with U174/U plug to be used in high impedance GA helicopter (Battery powered)
Completely opposite.......

Buy Pilot USA PA-87H Converts Hi-Impedance Helicopter Headsets to Low-Impedance Military configuration
This is the type I use. Converts my DC's from a GA aircraft to the low impedance. I use it in the 412.

We have a Zulu and 2 Bose X in our R44. We bought the Zulu because of the Bluetooth function - it can be really helpful to be able to talk to people on the ground. It works great.
As for the noise cancelling - the noise level in a R44 is no different to the Bose as far as I can tell. Both have great clear audio and are very quiet.
The Lightspeed however seems to have some problems with doors off operation. It tends to start to oscillate sometimes, which creates a low frequency sound, like blade slapping.
This is affected by how well it sits on my head at the time.
Has anyone had this experience with the Zulu?
It doesn't really bother me, I still prefer it because of the BT, and the fact that it has volume sliders instead of the wheels on the Bose.
Both are really comfortable, even after wearing them all day.

Does anyone out there use a lightspeed zulu for commercial operations, oil rigs etc?
Hope that helps.

Could you elaborate a bit more please.
Thanks in advance

Oops my bad, it was the Bose that hed the interchangeable headset. I asked the supplier if the Zulu would work in the S92 and he said that it would. There are different plug/cord arrangements though. Sorry.

DOH oh well thanks anyway SARBlade, on a good note Lightspeed now sell a low impedance version of the Zulu, I just got a confirmation email from them today.

I have had eight Bose Series X in several acft over the last 10 years and have had no failures of any kind including ear cushions. I have a Zulu because of the BT feature, I cant tell much difference in audio quality. I have a slight preference forthe Bose as it seems ligher and less bulky.
Although I havent tested this, I would guess that the Zulu has better passive noise attentation, but with acft powered headsets, I have never needed to deal with a power (battery) failure for the headsets.

I got mine here. They shipped it to my door in two days. Good lads! Ask them about the low imped mic version. Calgary Pilot Shop

My Bose X is 2 months past the warranty period and they refuse to repair it. This is the 3rd time it has failed in the 5 years I've had it.
That's the last Bose I will ever buy.
Lightspeed have been very good good in replying to emails. I can confirm they do offer the Zulu with either the low or high impedance mic. They quoted $900 dollars for either choice.

beyer dynamics or lightspeed?????
i am about to buy a lightspeed or beyer dynamics... any one has a feedback on the beyer????
bose x was discarded for all people saying haow many times it broke !!!!
the deal with the beyer is the DANR Digital noise reduction microship....
the dealer say it does "auto adjust" to the helicopter's frequency.....
right now i am flying R44/b206's but maybe will go for ec 130 soon,
if any one has a feedback on that would be nice!!!
fly safe for all!!!

Be sure to check the impedance of the a/c you are flying and order the correct mic.
I may be wrong, but the a/c you have listed are probably all high impedance, but double check as they are not interchangeable.

Interesting to hear the bad reports about Bose X from some members. I've owned a pair for over 5 years and have given them a serious work out with no problems. All the other pilots i fly with (7 of them) all have Bose X and none of them have had one single problem.
I did a test with a students brand new Zulu and my 5 year old Bose X in a Hughes 300 yesterday and found that the Bose has fair better sound quality. I think the difference with ANR was negligible.
My opinion is to pay the extra money and buy the better quality unit, The Bose X.

Not sure what environment you are flying in, but I'm using mine offshore in the tropics (mostly). Estimate that in the last 5 years I have put about 2500 hrs on them. As I said failed 3 times. Once was a buzzing in one ear cup, the other two were failed cords (broken wires).
I too liked the noise cancellation, however when the batteries go dead there is zero protection.
Mostly I'm not impressed with Bose not standing behind something that is clearly a weakness (cords), this last mic assembly only lasted 2 years.

hey all, new here to the forums! i just got a new bose aviation x and went to try it out in my school's R22 today and i could hear through the earphones, but could not transmit. the owner of the school says it could be something with the impedance of the mic. i dont know how to tell the impedance just by looking at it. please let me know what other info i can give so i can get an accurate answer. thanks in advance for the help!
