This adapter converts a low impedance microphone and phone military headset into higher impedance for use in general aviation aircraft. It also converts the U-174/U plug on the military headset into .206" and .25" plugs used in general aviation; 25 inches in length.

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.

Lowest Price Guaranteed!

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.

Doesn’t integrate perfectly with my Bose headphones I used in the AWACS

  • By Stef from Pittsburgh PA USA on Wednesday, June 15, 2022
  • Pros: It does work, and I haven’t had the chance to use them with another pair of David Clark’s to see if it’s the headset or the connector. It works well enough for my passenger, but not a co-pilot.
  • Review: I use this connector to connect my Bose headset I used on an AWACS to my DA40 GA aircraft audio panel. It may be my headset and not the connector, but whenever I speak into the headset a light clicking follows for the next several seconds and then dies out. Not ideal, but works well enough for a passenger.

Adapter with a hum

  • By James from Cincinnati OH USA on Monday, April 25, 2022
  • Pros: Makes my single prong headset useable
  • Review: I use this product as an adapter/converter for my military Bose A20 headset for a B-737. While it successfully takes my one prong headset and turns it into two, there is a loud hum of feedback that is associated with it. Not sure if I got a bad product or if this is normal with these adapters. Either way it’s a bit frustrating. I’d possibly look at another adapter without the humming feedback.

17 QUESTIONS & ANSWERS

  • Previously Asked Questions

  • Wednesday, January 31, 2024

    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)

  • Sunday, October 22, 2023

    Q: Will this work with Bose A20 military helicopter headset?

    A: Yes, this will convert your U174 Military plug to general aviation dual plugs. 

  • Sunday, October 23, 2022

    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.

  • Tuesday, August 16, 2022

    Q: Will this work with a Flightcom E13 military headset ?

    A: Yes, this should work to convert the Flightcom E-13 Military headset.

  • Friday, March 25, 2022

    Q: Will this work with my David Clark H10-76 Military Headset?

    A: Yes, it will.

  • Friday, January 28, 2022

    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.

  • Saturday, July 10, 2021

    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.

  • Thursday, November 16, 2017

    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. 

  • Sunday, January 22, 2017

    Q: It works for Bose Aviation X military headsets?

    A: Yes it will work for that headset. 

  • Tuesday, January 03, 2017

    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.

  • Wednesday, February 25, 2015

    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.

  • Wednesday, July 02, 2014

    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.

  • Thursday, August 09, 2012

    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.

  • Tuesday, August 31, 2010

    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.

  • Wednesday, April 02, 2008

    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.

  • Monday, September 10, 2007

    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.

  • Wednesday, September 05, 2007

    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.
