The device works as advertised. Having to unplug the headset to eliminate battery drain is annoying and sometimes forgotten. Regardless, I am getting about 100 hours per 9V battery. One problem I have had is that the output is too high for the audio panel in the aircraft. There is no way to adjust the gain so some microphones cause break-up and distortion, especially when picking up high background noise, which is common in military aircraft. Add a power switch and adjustable mic gain and this would be a 5-star device.

It works but only intermittently. Can’t really rely on a product that intermittently cuts out. The vox worked semi decently for a couple hours, then wouldn’t activate when I spoke. I’d have to play with it to get the vox to activate again.

Q: I have a David Clark H10-13X ANR headset. Will this adaptor allow me to plug into a military helicopter?

Yes, this will let you plug in a dual GA headset for use in a military aircraft using a single U/174 plug.

Q: What is meant by Battery Power 9V? and does it work with a Bose Noise Reduction Headset X as well?

Yes, the ANR on the Bose X will be powered by the batteries in the Bose battery pack. The 9V battery in this adapter is to change from high to low impedance.

Q: I have a General Aviation (2 prong) Bose A20 Headset. Will this work to convert my headset from high impedance to low and let me use my headset in a Blackhawk and Lakota? One is a true Military helicopter and the other is a civilian piece of junk. However they use the same size prong just diffrent impedances.

This will not do both conversions. This adapter, Part # 11-06529, will convert your Bose A20 Dual GA to military low impedance single plug for use in the Blackhawk. To convert from Dual GA to single plug high impedance for GA helicopters like the Lakota, you will also need part # 11-10630.

Q: I have a Lightspeed Sierra headset. I need to plug into a military fixed wing. (C-130H) if that makes a difference. What adapter do I need?

This is the right one, Dual GA to Military U-174 low impedance adapter.

Q: I have a Bose A20 dual plug GA headset. Which part will convert this to civilian helicopter single plug?

No, you will need Part# 11-14138.

Q: How long time operation hour by alkaline battery? And if the battery dead in flight, can I talk continuously ?

40-45 hours continuous usage. But it is important to disconnect the headset from the adapter after you are done with the flight. Yes, if the battery died the headset would stop working.
