This will work with a variety of military headsets including, but not limited to, the popular David Clark H10-76, H10-76XL, and the Bose A20 military headset model 324843-W130. If you are planning on using this to convert the DC H10-76 for use exclusively in civilian fixed wing aircraft, we recommend using the David Clark H10-76 conversion kit instead. The conversion kit will swap out low impedance mic with a high impedance mic. However, if you will be switching back and forth between military and civilian, we recommend using this impedance adapter instead.
If you find a better price elsewhere on this product we will Match that price and beat it by 10% of the difference. See Details.
Purchase today and you can return it in the original condition through Tuesday, July 7, 2026! See our return policy.

Verified PurchaseQ: I was told this will work from military helicopter single point plug to civilian helicopter. Is this accurate?
A: For converting from a low impedance military headset to a general aviation helicopter you would want to use the Low to High Impedance Adapter (Helicopter)
Q: Will this match speaker impedance on a DC H10-76xl or just mic impedance? Can I expect good speaker volume in GA?
A: Yes, this works well for to convert the David Clark H10-76XL to civilian airplane use. It''s a very common use of this adapter.
Q: Hi I’m looking for some adapter from GA to MILITARY comms, Do you have it?
A: If you want to go from GA to Military, you would need the opposite adapter. For that scenario, you would want to get the High to Low Impedance adapter.
Q: Will this work with my Bose A20 that I used on a KC-135 to a GA DA-20?
A: Yes, this will convert your military headset to be used in a general aviation system.
Q: Would I be able to use a bluetooth cable assembly with this?
A: Theoretically, yes. But, if you are talking about a Bose A20, then almost all of the Low Impedance (military) headsets are non-Bluetooth. The only Bluetooth military headset that Bose made was a High Impedance headset. Can you reply with more details about what you have right now?
Q: I have military Bose a20 for military C17 aircraft, does this work to convert to civilian airframe (embraer 190) ?
A: No, it will not. The Bose A20 for C17 headset is a unique product and different from most military headsets. The only way of converting that particular headset to civilian use is to get a new Bose A20 Cable Assembly for your application (i.e. if you need dual plugs, get the Bose A20 Cable Assembly Straight Cord, Twin Plugs)
Q: Will this work with Bose A20 military helicopter headset?
A: Yes, this will convert your U174 Military plug to general aviation dual plugs.
Q: Will this work with my David-Clarke H10-46 headset?
A: No. The David Clark H10-46 was a civilian helicopter headset. Instead, you would want the helicopter to fixed wing adapter.
Q: Will this work with a Flightcom E13 military headset ?
A: Yes, this should work to convert the Flightcom E-13 Military headset.
Q: Will this work with my David Clark H10-76 Military Headset?
A: Yes, it will.
Q: Hi there, I have just purchased a David Clark One - XM (military low impedance) headset and need it for GA use. Will this adapter work to convert it? Or do I need a different adapter?
A: Yes, this will convert the David Clark One-XM to GA use.
Q: Will this work with the U-174/U plug?
A: If you have a military U-174/U plug, this is the correct adapter. If you have a civilian helicopter headset with a U-174/U plug that you are trying to adapt, then you would want the Helicopter to Fixed Wing adapter instead.
Q: Does this adapter can connect with Bose A20 U174 military single plug headset into Boeing aircraft(dual GA plug) ? TKS!
A: If you are using a military headset, then yes. This will convert a military headset for use in a civilian aircraft using the dual plugs.
Q: It works for Bose Aviation X military headsets?
A: Yes it will work for that headset.
Q: I have a military A20 and am looking for an adapter to a Boeing and McDonald Douglas airliners. Will this work? Ive heard mixed reviews. Also, what is your return policy in case it doesn't work. Thanks
A: Yes, this will convert your military A20 to use in civilian aircraft. You can return it in new condition within 30 days.
The other route would be to get a new cable assembly either without Bluetooth or with Bluetooth.
Q: Hi, I have a mil Bose X helicopter headset with U174 plug. Do you have one that does not split in to the 2 pins for fixed wing aircraft, but just extend to a U174? In other words a female plug for U174 and a male 174 ? Lastly will this work on this headset.
A: Yes, we have the 5 foot Helicopter Extension Cable that will do exactly what you need. This will extend the length of a civilian helicopter headset or a military headset since they both use the same U-174/U plug.
Q: Does this part work without issue on a Flightcom E-13 ANR low impedance headset?
A: You will need the David Clark H10-76 Conversion kit. That should convert the Flightcom E-13 as well since it's the exact same technology as the David Clark H10-76. Both the E-13 and the David Clark H10-76 have the M-87 microphone and the E-13 was built as a "copy-cat" of the H10-76.
Q: Hello. I have a military Helicopter helmet. I want to use it for civilian Helicopter use. Your low to high impediance adapter goes to a two prong civilian fixed wing. Do you have a low to high single prong or do I have to use a combination of adapters. Thanks
A: Hey Kris! You're in luck, as we do carry the Low to High Impedance Adaptor (Helicopter)! This will convert a low impedance military headset with a single U92A jack for use in high impedance general aviation helicopters.
Q: hi i have a helmet with u-174 plug.is this will fit for general aviation? and how long is it. thanks.
A: If your helmet has a low impedance connection/headset and is not the David Clark H10-76 then this will work. The adapter is 3' in length.
Q: I have a military helmet with a u93a/u plug that I want to adapt to general aviation radios. What adapter do I need? Thanks roger
A: Which headset model do you have? If you have the David Clark H10-76 you will need the David Clark H10-76 Conversion Kit. Otherwise, you should be able to use this adapter for the conversion.
Q: Hi. I have a mil-spec version of the Bose X headset that I'd like to use in commercial aircraft (BE-400). Will this adaptor work with the Bose X headset? Thanks.
A: We have not specifically tested this adapter with the Bose Military headset, but it should work. If not, we have a 30-day return policy.
Q: Hello, why will this adapter not work with the H10-76? Would it work if I use another low impedance mic with the H10-76, or is there another reason? Many thanks, Christoph Zimmermann
A: No, this will not work for a David Clark H10-76. Instead, you will need the 1142-22 Electret Mic found here: https://www.mypilotstore.com/mypilotstore/sep/2162 and the JB-08 adapter that is linked from that page.
