My first ANR was a Headsets Inc. ANR module added to me David Clark headset.
The first takeoff with this headset resulted in an aborted takeoff. I
instinctively aborted the takeoff because the engine "did not sound right."
After checking all the gauges and thinking things through, I realized that the
problem was not in the engine but in my head. Once I have gotten used to the
ANR, I feel that I can hear the engine a lot better with the ANR than without
it. By reducing the noise, I can hear sounds which were previously masked out.
I now fly with a DRE ANR headset, which I find better than a David Clark with
the Headsets Inc. ANR mod. The passenger gets to use the DC. If you have a
headset already, adding the ANR kit makes sense. It does not make sense to buy
a headset and modify it. For what it will cost you to do that, you can buy a
DRE, or a Lightspeed or a number of other sets, at least some of which you will
find better.
If you already have a headset that you want to keep, the $100 kit will provide
a world of improvement. Just keep in mind that you need gel ear seals. If you
don't have them already, factor that in the price as well.
