Mike, Mark; and all you going deaf with noisy Rotary engines:
I have 2 sets of Halo Tubephones from Quiet Technologies, that provide about 30 dB of quieting at 125 Hz, and up to 45 dB at 4,000 Hz and higher. They sell for $360 each at www.quiettechnologies.com, or their booth at OSH.
Not connected in any way to them. Just a satisfied customer, especially after flying with my brother who was using his $1,000 Bose headset. We swapped, and both of us found the light Tubephones to be quieter and more comfortable.

Good report Mike. I know what you mean about a quieter muffler. My ANR headset does a good job of killing the low frequencies, but a poor job on the higher frequencies. The rotary has both. So take your pick, turn the ANR on and listen to the high frequencies, or turn it off and listen to the low rumble. If I could only find an ANR that can do both I would be a happy camper. Mark

I added another 1.3 hours to my total flight time today. And for
the first time I landed and was completely satisfied with the
flight. I'd still like to quiet it down a little, but this was the
first flight where I didnt feel like there was anything that had
to be fixed before the next flight. Even the landing was pretty
decent.
I've got just over 9 hours of flight time and about 40 hours of
engine run time now. So far all of my flight time has been
directly over the airport because to venture away requires flying
over about 50 miles of mostly unlandable mountainous terrain. But
I'm starting to think seriously about stretching the legs a little...

Mark,
Which ANR do you use?
Best Regards,
