The M-001-A ANR Adapter is a product that will transform a current aviation headset into a high-tech active noise reduction unit. The ANR Adapter comes as a kit and includes a pair of inserts that fit more than 20 different headset models. Installation requires fitting the inserts, drilling a small hole in one earcup for the power receptacle, and soldering the original cable leads to the kit replacement parts. (uses one 9-volt battery).
It is mandatory that you use "silicone gel" type earseals. The original earseals (dry or liquid filled) are not as airtight as gel seals, and in addition do not dampen sound and vibration as effectively.
The result is that the ANR units will greatly underperform (20-50%) and will be more likely to malfunction. Several brands of gel earseals are compatible with the ANR modules. These include David Clark gel ear seals, AvComm gel ear seals, FlightCom gel-flo ear seals, and Sigtronics gel earseals.

Works very well
I installed this kit in my SPH-5 helo hemet. It was a bit tedious, but that was to be expected. This made a huge difference in the amount of noise in my PA-12 160. I used to have to use earplugs on anything other than local flights. As far as the installation goes, you need to be deft with your soldering or it isnt going to go well. It isnt electronics, but you need to be careful and follow the instructions, which I found well-written. I had one problem (my fault) because of reading the instructions wrong, so I called the manufacturer. The owner answered the phone. There you go.
Thanks to SCOTT J VALENTI I have ordered the AMP cable. I would have been pissed without it. Note to Spruce: you guys rock but you need to keep up with stuff like that. Quite a few times I ordered stuff that requires other items and its either not mentioned at all or its mentioned like: see below for XXX part and there is nothing below...
Purchased a kit last week for a 25 year old David Clark H10-30 headset. For the first time, I spent about an hour and a half on this installation. The results were remarkable. I am very pleased that I purchased this retrofit kit, the David Clark gel ear seals, new wide headband and a M7/DC retrofit microphone kit. Total cost of new parts is about half the cost of a new David Clark ANR headset.
A great alternative to the very expensive ANR headsets out there. A little work involved, but satisfying results. I would get the optional power cord if doing it again, as the way they have you combine the two cords is kind of cheesy. Be sure to read a step or two ahead of your operation, because at one point you start soldering, only to find out that there was another step you should have taken before having to undo everything you just did. This was my second set, so I believe in this product.
Instructions are adequate but must be carefully reviewed and followed. You have to decide which paragraphs to skip since instructions cover an optional power harness. I skipped too much at first. It would be very helpful if the power cable was stripped to the proper 3 inch length in the kit as this is a slightly difficult operation. The colored wiring diagrams were very helpful. Make the 3 wires for the electronic module plenty long and trim them to a suitable length just before soldering to the modules. I installed this kit on a 40 year old David Clark H10-30. Performance is good, making a significant improvement in low frequency noise from a 200 HP IO-360 with 2 blade propeller. A good seal to your ears is important and was possible wearing eye glasses using gel ear seals. I compared side by side to a Bose A20. The Bose A20 is significantly better but significantly more expensive. Overall, the upgrade is a very good value if you own a passive headset.
I just received my kit today. The parts are all there and packaged in a professional manner. The instruction booklet seems real good. However, I already have an issue. The instruction booklet mentions an optional AMP cable. Hmm, why didn't I get this? Oh, it's because I didn't know it existed! Why would someone spend $159 on the ANR kit, but not an extra $33 on the AMP cable? So, I ordered the AMP cable just a few minutes ago. Save yourself some hassle and order them at the same time, OK? Or maybe you're smarter than I am, and already noticed the AMP cable is listed on the ANR retrofit page, and you've already added it to your shopping cart. Good for you. There is a nice list of tools required, in the instruction booklet. They are: 1. Fine tip soldering tool ( 20w) 2. Small wire cutters 3. Small screwdriver set 4. Sponge to clean solder tip 5. Butane lighter to heat shrink wrap 6. Continuity tester (optional) Also, if you don't get the AMP cable, you'll need a drill with 1/8, 3/16 and 1/4 bits. (Another reason to get the AMP cable!) Just thought I'd list the tools here so you can make sure you have them, ahead of time. Thanks.
Yes, these kits are made by Headsets Inc.

Yes, this will work with your headset.
No,this is a retrofit kit and comes with a battery pack , cabling and all necessary installation materials.
That depends on the headset. It can be used with both stereo and mono headsets.
