Pilot USA PA 88 Military To Dual GA Impedance Adapter

This is my second adapter I bought to use with one of several military headsets I have and it works phenomenal!!! This works great with my military Bose A 20s I use for flying that is single plug. I was hesitant at first because people kept saying the impedance adapter didnt work for them but I went ahead and decided to try it anyways and Im glad I did. These are a huge cost saving over buying a new nose that is almost a grand. My guess is the people that complained bought the dual plug adapter and not the dual plug impedance adapter.

Pilot USA PA 88 Military To Dual GA Impedance Adapter

Worked great with a Bose X military headset in a C-182.

Works great with my Mil surplus acft headset and the headset adapter for my Yaesu FTA750L HT.

Tested it on the ground and it seems to work just fine. Thank you! I appreciate the speedy delivery as well.

Works great with my military David and Clark headset. Would highly recommend.

Currently using my military Bose A20 on GA aircraft and this adapter is making it happen. Works great!

I flew with this yesterday. It works exactly as advertised. My MILSPEC H10-76 sounded and performed just like my civilian headset in the airplane. Good deal for the money.

This adapter works perfectly with my Bose A-20 headset. Good quality, fast shipping.

Bought two for old USAF HGU-55/P helmets with military boom microphones. Worked flawlessly in civilian Varga 2150A aircraft (light GA single engine, common intercom and radio components). Really great, easily reversible way to make use of your military helmets and headphones!

This works perfectly with my older Bose X military headset.

Great quality adapter that does what it says. I have military headsets (fixed wing) and I need them to work on GA aircraft. I got 2 of these and problem solved.

Used it on my bose A20 (non-Bluetooth) military headset and it worked exactly as advertised in a C-182, I heard everyone inside and outside the plane and they heard me too. Its a little expensive but if you need a mil-to-civilian converter( single plug to dual) this is what you need.

It worked perfectly the first time out of the pack. Great product.

This unit allowed me to use a military David Clark headset in a GA system. I cant tell the difference between this system and a stock GA system. I have not used it for a long period yet, so dont know if heating up will change performance. This sometimes happens in headsets.

Great quality adapter. It worked flawlessly with my flightcom e-13 military headset. It is somewhat bulky and is different than the picture though.

Works great! Bought it to convert an HGU-55p helmet with MBU-12 mask into civilian impedance for use in L-29 and de Havilland Vampire jets. I had heard that sometimes these adapters can be finicky, but this one has been working flawlessly on multiple different helmets in both jets!

So far it has worked as advertised, completed 3 flights in a piper pacer. Only issue I have had is I didnt push the helicopter plug all the way in one time and could barely hear until I realised my mistake. Could be a bit cheaper but then again what is in aviation.

The product is fine. But i was told it would work with my military headsets. It doesn’t!! I spoke with Customer service and they were to get with the manufacturer and reply back with a phone call almost 2 weeks ago. I’ve not heard anything further!!

Pilot USA PA 88 Military To Dual GA Impedance Adapter

Works with my military Bose A20 but there’s noticeable feedback when talking outside or on hot mic. Will be returning.

Very disappointed. I bought this to use with my SPH4 helmet. I chose the PA88 because it was supposed to be compatible with the DC 10/76 headset, which uses the same microphone as the SPH4, and because of customers reviews of excellent support from Pilot USA. It works fine on intercom, but when when the transmit button is pushed, there is a very rapid clicking sound. I emailed Pilot about the problem. No response. After 5 days I called Pilot and was assured that the responsible manager would call be in the next hour. It is three days later and no return call. I gave it two stars instead of one because Aircraft Spruce is great and has always been my first stop for shopping. Pilot USA seems to be something else.

Doesn’t work when you try and convert a military Bose A20 into a 737. On hot mic a constant buzz can be heard ....

Does not work and has to return.

Not happy with it. Tried adapting a very nice military headset to my PS intercom. Much static popping noise, then annoying constant white noise. Did not work. Very dissapointing.

The equipment was the exact same as a friend of mine uses on a Super Cub. I have borrowed his adapter several times, witout any problems. I ordered the exact same product - even the PA-88 labels matched and was identical. When I connected my helmet with the adapters purchased from you, the transmission was garbled, and ATC was not able to read my transmission. This happened with both sets. So - bottom line, I wasted approx 250 USD (187+tax&customs) on a useless product.
