Overview

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).

IMPORTANT:
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.

Reviews

Like many pilots I have had several headsets. I had a Bose X which worked well when I had my Mooney 201 but did only a fair job with my Europa homebuilt with a Rotax 914 as it did not suppress the high frequency noise from the Rotax. I purchased a Senheiser ANR headset as it had better high frequency noise attenuation but my old David Clark H10-13 was still better at the high frequency noise control when behind a Rotax but the low frequency propeller rumble was a problem. I was about to purchase a DC One X but saw a video review of this kit and thought I would give it a try ,having built electronic kits in the past it was, I felt, fairly straightforward and is now the best headset for flying behind a Rotax 914 I have ever had and is far superior in this case to my Senheiser ANR. The incoming voice communications are ok but you would not use it to listen to music as the lower frequencies are absent. I would highly recommend this for someone with an old DC headset and a Rotax powered aircraft. I converted my other DC headset for passenger use as well. ACS service was great as always but the first kit included the AMP accessory cord so I returned the extra one I purchased. The second kit did not include it so I had to purchase the AMP wiring set, which I highly recommend as it is neater. Could ACS explain why what kit had the AMP cord included and one did not?

Excellent product and really enjoying having the benefit of ANR at a much lower cost than buying a new headset. The install took 2 hours and the instructions are very thorough. Would highly recommend.

Works great in my RV4. First flight yesterday with the ANR mod installed in my DC10-13.4. Get the connector cable and save drilling a hole in your headset. Installation steps in instructions are sometimes out of order.

I have had the Headsets Incorporated (HI) ANR kit installed in my David Clark (DC) H10-13.4 for two years now. I installed the kit myself. I will comment on the individual phases of ownership below. Purchase: Made a phone call to be sure of any options available. This was pleasant, quick and easy. Installation: I am an experienced electronic engineer with thousands of build projects and repairs to my experience. I am also an audio engineer so I have a clue. The HI written instructions were just ok, but the color wiring diagram made it easy to complete the installation. I ended up reusing the DC foam from over their speakers in addition to everything HI furnished. It filled the small remaining void between the speaker and my ear. I also made some small deviations in construction that in no way effect the final product, like using shrink wrap in the connections. Its just me, Im fussy. Even though the HI speakers are held in assembly with the DC earcups with the finest double-sided tape I know, I wish another type of fastening was used but they have held up to frequent use for two years. Early use: At first I was getting squeals and other oscillations and was not happy with my purchase. It always seemed to happen about an hour into my wearing them. This happened multiple times in flight and I had to turn off the ANC power to stop the very loud squeal. Phone call to HI customer service: Got right thru to the main engineer at HI. Knowledgeable and helpful, we discussed possible solutions. In the end he offered to take them in to adjust them at no charge. Very positive experience. But I never sent them in. Read on please. Recent experience: The squeal and other sounds were caused by my unfamiliarity with how to wear the modified headset. Simply making sure the soft earcup was centered over my ears with my entire ear comfortably tucked into the open area (and not squished against my head by the gel pad) solved any and all issues. I have worn them for up to five hours in a day. Most people put these DC type of headsets on and squish their earlobe between the cup and their neck and call it good. Even PNR headsets will eventually cause your ear lobes to ache due to reduced blood flow. Just tuck your entire ear in the open area and these HI ANRs work wonderfully. Final thoughts: Simply knowing how to wear the headsets solved all issues. I have used these HI ANRs for hundreds of hours. I tow gliders, and in 24 months have about eight hundred tows in my log book (all with the HI kit) so you know I have put in some hours while benefiting from HI ANR. Installation was easy for me. Customer service was willing to help. The kits are reliable. I just had to learn how to place the headset on my noggin. John

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.

In the end, this kit met all my expectations. However, the instructions were confusing and in some areas contradictory. As an example in the last pages you are instructed to insert foam insulation under the wiring before making the connections. Another instruction required a butt splice of four wires that later had to be cut and soldered differently. Most of the confusion comes from the inclusion of the AMP cable in the kit. A good thing. Best to simply follow the color wiring diagram on the supplemental sheet for mono or stereo installation..
