Well, you have your opinion, I have mine, we'll just leave it at that. By the way, I DO get it. I understand that the Bose has no passive capabilities. But the others on the market, like Telex, Lightspeed, and the DC ENC's do have passive reduction in addition to the ANR. The last two seasons I was flying ag, I was using an HGU-33 helmet with an ANR conversion kit that came from Flightsuits, Ltd. in El Cajon, CA. Best investment I ever made sitting behind a 1340 radial all day. I guess you've just had a bad experience, but ANR DOES work. My experience has proven that to me, and that's all the proof I need.
