For those that fly with helmets, do you know of a good ANR upgrade kit for the ear shells? I do have the Oregon Aero passive hush kit but am thinking about upgrading the shells to ANR.
I upgrades my helmet to ANR when I was using it all the time in flight testing - it is still very comfortable and quiet (not as comfortable as a Halo, but sometimes, you want a helmet).
I installed the Headsets Inc version about 8 years ago in a set of Peltors.
I think they are great. The instructions were clear and it was fun to do.
I had no idea how loud cars are until I tried them on the way out to the airport for the first flight!
Anyway, I can vouch for the quality of mine, and I don't even work for them or anything!
I have a set of headsets I modified with a Headsets Inc kit in 1996 & they still work great. Their helmet kit is slightly different than the headset kit, but the electronics should be similar.
